While they can rotate at extremely high speeds, they cannot support substantial loads. The following are some key considerations and benefits of ball or spherical bearings.

  • Provide low friction rotation
  • Optimal for high speed applications
  • Good wear resistance
  • Essential to ultra-precision applications
  • Have limited load-carrying capacity
  • Support axial and radial loads with specific configurations
  • Standardized to permit easy replacement and interchangeability
  • Available in different roller shapes and in single– or multiple–row configurations

solutions for a wide number of industriesBall Bearings Types

Angular Contact Ball Bearings

Angular contact ball bearings bear radial and axial loads through asymmetric raceways. These raceways position the spherical rolling elements (also known as bearing balls) within the bearing at a certain angle. The smaller the angle between the bearing and the axis, the greater the axial load that the bearing can withstand. We offer three different series, 7000, 7200, and 7300.

Deep Groove Ball Bearings

Deep groove ball bearings are a type of ball bearing that has a “deep groove,” or radial raceway. One of the special features of these bearings is their ability to support radial and axial loads in both directions. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They are easy to mount, and require less maintenance than other bearing types.

Double Row Angular Contact

Double Row Angular Contact ball bearings have two rows of balls arranged back-to-back. The lines of action of the load at the contact between balls and raceways (load lines) diverge at the bearing axis and form an angle of 30° to the radial plane. In essence, they work similarly to having a matched pair of Single Row Angular Contact ball bearings either face-to-face or back-to-back.

Double Row Angular Contact

Miniature Ball Bearings

Miniature ball bearings are often referred to as instrument bearings or micro bearings that reflect their small size. Despite their compact dimensions, these bearings are engineered to provide dependable, high performance within small envelope dimensions for moderate thrust and radial load at low operating torque speeds. Precision tolerances from ABEC-1 through ABEC-9…

Miniature Ball Bearings

Self Aligning Ball Bearings

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles. They are available open or sealed. Self-Aligning Ball Bearings are designed to work in applications…

Stainless Steel Ball Bearings

Stainless steel balll bearings are manufactured in AISI-440C, that is the most common material used for stainless steel bearings due to its high hardness, corrosion resistance, and low magnetic permeability. The stainless steel shields and retainers are usually made from AISI-304 stainless steel but some sizes are available with a reinforced polyamide retainer. Rubber contact seals…

Stainless Steel Ball Bearings

Thin Section Ball Bearings

Thin section ball bearings are precision-engineered components designed for high performance in applications where space, weight and noise levels are critical considerations. As the name implies, the difference between the inside and outside diameters of the rings has been minimized or thinned out. They offer high load capacity, low noise and exceptional rotational accuracy.

Thin Section Ball Bearings

Thrust Ball Bearings (Single-acting)

Thrust ball bearings are designed for axial loads only, and cannot handle much radial load at all. The thrust ball bearing consists of a shaft washer, a housing washer, and a ball set with cage. It can be a valuable solution for applications requiring pure axial loads. Therefore, they are not suitable for applications involving radial and axial loads simultaneously.

Thrust Ball Bearings

Mast Guide Bearings (Guide Rollers)

Mast guide bearings are bearings found on heavy-duty equipment such as forklifts. Typically used as guide rollers in high radial or thrust load applications, mast guide bearings have a thick cross-section on the outer ring that performs as a tire or wheel. Mast guide bearings are mounted on the fork carriage and facilitate smooth movement as the forks are lowered or raised.

Mast Guide Bearings

Ceramic Ball Bearings

Ceramic ball bearings are specialized bearings that feature ceramic balls encased by either ceramic or steel rings. The balls within the assembly of a ceramic ball bearing are made from ceramic materials such as silicon nitride or zirconia. The hardness of ceramic materials ensures superior resistance to wear and deformation, even under heavy loads and high-speed rotations

Ceramic Ball Bearings

Electric Motor Quality Bearings

Electric Motor Quality (EMQ) Bearings require bearings and fabricated components that can support long-term performance. EMQ Bearings are designed and Noise Tested (NT) to meet a noise quality standard. All EMQ Bearings are available in C3 Fit. Metal Shields for higher speed applications, contact rubber seals for dirty environments or where moisture is present, and 2VS Viton Seals…

Stainless Steel Fishing Reel Bearings

Standard & Ceramic Hybrid, Stainless Steel fishing reel bearings are available in ABEC 5 & ABEC 7 for all of the popular fishing reels. Ceramic by its nature is lighter than steel by about 2/3 the weight, it is harder than steel when it is in ball form and it is virtually frictionless because it is non-porous. Ceramic hybrid bearing has steel races with ceramic balls. The balls will never corrode or rust.

Stainless Steel Fishing Reel Bearings

Flanged Miniature Ball Bearings

Flanged ball bearings are equipped with a flange on the outer ring. This flange serves multiple purposes, including facilitating easier location of the bearing within a housing and preventing axial movement in the event of a thrust load. Particularly in applications with significant vibration, maintaining the position of a flanged bearing in the housing becomes easier.

Flanged Ball Bearings

Slewing Ring Bearings

Slewing ring bearings, or turntable bearings, are ball or roller-style bearings composed of two concentric rings, either of which may include a gear. This type of bearing enhances load support and power transmission in all directions, and they are typically employed to support heavy loads for slow applications and large equipment such as earth excavators and construction cranes.

Slewing Ring Bearings

Super Precision ABEC7/P4 Bearings

Super Precision Bearings are parts made to help machines work super fast and super accurately. They’re built with advanced materials and are very precise, so they can deal with tough tasks smoothly. When high speed and accuracy are necessary, super precision bearings — also known as extra- or high-precision bearings — are typically employed.

How Are Ball Bearings Made?

The material used and the overall design features of a ball bearing can vary drastically depending on the application requirements. Commonly used materials include:

  • Chrome Steel
  • Stainless Steel
  • Ceramic

Millions of ball bearings are produced annually, with chrome steel being the most commonly used material. Chrome steel bearing balls are almost perfectly rounded and offer a polished, mirror-like finish to provide precision rotary motion in hundreds of industrial applications. The production process of ball bearings involves:

  1. 1
    Heading

    The manufacturing of steel balls includes a steel rod or wire, which gets cut into small pieces (slugs) during the first step of the process. The slug is then fed into a header machine, where the metal balls undergo a cold-forming process (heading).

  2. 2
    Flashing

    Excess material, known as burrs or flash, must be filed away from the metal ball. The flashing process (filing) occurs while the metal is still soft and not yet perfectly rounded. While there are two machining variations commonly used by manufacturers, both involve rolling the balls between two metal plates.

  3. 3
    Heat Treating

    Once the excess material has been removed and the balls are relatively round, they undergo a heat-treating process to strengthen and harden the material.
    The steps include:

    • Heating the balls to 1,500ºF
    • Quenching the balls in an oil bath
    • Re-heating the balls at 325ºF to ensure thorough hardening
  4. 4
    Descaling

    Heat treatment causes discoloration and oxide deposits to develop on the balls. The balls undergo a descaling process to remove these spots. An acidic compound, or another chemical agent, is used during descaling to remove any build-up from the metal balls.

  5. 5
    Grinding

    Once the balls are relatively round and hardened, the next phase involves grinding the balls to achieve proper size and improve the roundness geometry. Similar to soft grinding, the balls get rolled between a fine-grit grinding wheel and a steel plate.

  6. 6
    Lapping

    The final step in the manufacturing process is lapping. This super-finishing process improves the geometry or surface finish, removing trace amounts of material so the ball achieves tight tolerance requirements.

  7. 7
    Washing

    Once manufacturing is complete, the balls are washed to remove leftover residue. The clean metal balls are then inspected for size and signs of scratches or other defects.

QualityPrecision Vs. High Precision

Generally speaking, precision ball bearings comply to ABEC-1 and ABEC-3 tolerances while high-precision ball bearings comply to ABEC-5, ABEC-7, or ABEC-9 tolerances. Some general purpose ball bearings intentionally do not comply to the ABEC precision tolerance specifications and are not graded nor rated as such.
