Linear bushing bearings and linear way products incorporate several rows of recirculating balls or rollers for low friction and precise linear motion. Linear bushing bearings use a round shaft and linear way bearings have a rectangular shaped track. Both the inch and metric types are available as standard, adjustable and open, both with and without selas, depending on the requirements of the applications. The linear way series offers standard, wide, carbon steel and stainless steel variations.

We offers the world’s largest selection of state-of-the-art linear bearings. Choose from several families of inch or metric linear bearings and accessories to meet your specific design needs, including our Super Smart Ball Bushings, which offer load capacities up to 7760 lb. When used with RoundRail linear guides, the inherent self-aligning-in-all-directions design of these linear bearings allows for ultra-smooth travel when mounted to wider-toleranced prepared surfaces. When used with shafting, our linear bearings last up to 50% longer than conventional bearings.

RoHS Compliance

The Restriction of the Use of Certain Hazardous Substances (RoHS) in Electrical and Electronic Equipment (EEE) Directive (2011/65/EU) bans the placing on the EU market of new EEE containing more than the agreed levels of lead, cadmium, mercury, hexavalent, chromium, polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) flame retardants and some phthalates.

We confirm that all are RoHS compliant.

  1. 1
    Linear Motion Ball Bearings

    Angular Contact Ball Bearings carry combined loads, both radial and axial, designed, much like the super precision bearings, for high-speed and high-precision applications.

  2. 2
    Compact Ball Bearing KH Series

    Automotive AC ball bearings and Air Conditioner bearings, are suitable for the high-speed applications Automotive A/C compressors require. They are typically double-row ball bearings, rubber sealed on both sides, and pre-lubricated with high-speed grease.

  3. 3
    Flange Linear Bearings

    Ceramic ball bearings are made entirely of ceramic material and are superior to common steel bearings in many ways.Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction and heat. Ceramic balls require less lubricant and have a greater hardness than steel balls which will contribute to increased bearing life.

  4. 4
    Linear Bearings with Steel Cage

    Deep Groove Ball Bearings are incredibly versatile and the most widely used. Due to their low friction, they are capable of high rotational speeds, supporting both radial and axial loads. Bearings Direct offers both in metric and inch sizes , also we stock stainless steel made materials metric and inch sizes.

  5. 5
    Linear Motion Ball Bearing Slide Units

    Electric Motor Quality (EMQ) bearings are designed and and Noise Tested to a noise quality standard. All EMQ Bearings are available in C3 Fit (with limited sizes available in C4 fit). EMQ Bearings offer to include Ceramic Hybrid Balls. Ceramic balls have an even greater density and hardness than a standard ceramic ball.

  6. 6
    Flanged Motion Ball Bearings

    Stainless Steel and Ceramic Hybrid fishing reel bearings are available in ABEC5 & ABEC7 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 less friction because it is non-porous. A ceramic hybrid bearing has steel races with ceramic balls. The balls will never corrode or rust.

  7. 7
    Support Rail Units

    Miniature Ball Bearings are small bearings with bore sizes between 1 and 10 mm or up to half an inch. A number of miniature ball bearings are in both metric and inch sizes that meet ABEC1, ABEC3, ABEC5 and ABEC7 precision class. Bearings in this series are designed for moderate radial and thrust loads at a low operating torques.

  8. 8
    Linear Shaft Support Blocks

    Self-Aligning Ball Bearings are double-row balls and one concave spherical raceway in the outer ring, that can adapt to both static and dynamic angular misalignment. As a result the bearing is self-aligning and insensitive to misalignments of the shaft in relation to the housing.

  9. 9
    Linear Slide Shafts

    Stainless Steel Ball Bearings are manufactured in AISI-440C rings made from the more corrosion resistant. The stainless steel shields and retainers are usually made from AISI-304 stainless steel but some sizes are available with a reinforced polyamide retainer. All sizes can be supplied with stainless steel shields or rubber contact seals.

  10. 10
    Compact Linear Bearings

    Deep Groove & Super Precision Radial Ball Bearings consists of super precision ABEC7/p4 bearings with a phenolic retainer. These bearings are perfect for high-speed and precision applications.

  11. 11
    Linear Bearing Belt Lubrication Device Series

    Thrust Ball Bearings are ball bearings that can carry axial loads alone. Bearings Direct supplies thrust ball bearings that are single row, in both miniature and regular three-piece configurations.

  12. 12
    Super Linear Ball Bushings

    Wire guide bearings are available in inch and metric styles. They are available with extra thick cross sections for increased life. They are distinguished by a groove that, while typically 90 degrees, can be produced in various angles and contours. Grooves can be provided on most Ball Bearings, Cam Followers and Yoke Rollers per customer specification.

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.

ProfessionalHow to Mount & Dismount Bearing

Successful mounting is critical to the life cycle of your bearing. Proper bearing dismounting can safeguard other machine components and maintenance workers. The rolling bearings mounting and dismounting web application provides step-by-step instructions

PerfectionBearing Failure & How to Prevent

The bearing is at the heart of all rotating equipment, and the condition of the bearing often reflects how well a machine is running. Sometimes, however, bearings fail. In these cases, what’s the first thing you should do? Learn more about bearing damage and bearing failure – and how to prevent it.
