Linear bearings and linear rails products are designed to provide smooth and precise linear motion by incorporating multiple rows of recirculating balls or rollers. Precision linear bearings are designed for use with a round shaft, while linear rails bearings have a rectangular-shaped track. Both the inch and metric types are available as standard, adjustable and open, both with and without seals, depending on the requirements of the applications. The linear guides series offers standard, wide, carbon steel, and stainless steel options. This allows for flexibility in selecting the most suitable linear rail product for the desired application. Whether you need linear bushing bearings or linear rail and bearings, our inventory provides a comprehensive selection to meet your specific requirements. Choose the right product to achieve low friction and precise linear motion bearings for your applications.

At NPBS Bearings, we offer a diverse range of linear bearings (linear slides bearings) that are suitable for various applications. Our linear sliding bearings are readily available in our inventory for online purchase. You can explore our inventory below or request more information by contacting us here.

Supplying Linear Bearings Of Virtually Every Type

NPBS Bearings Co., Ltd. offer a wide variety of round shaft linear bearings, housings, shaft supports & linear shafts.

The ball bushing range includes open and closed, compact, super and stainless steel linear bearings. The housings are available in aluminium, cast iron and stainless steel in open and closed versions as well as tandem length and quad blocks. The linear bearing shafts can be hardened and ground (Cf53), chromed or stainless steel (X90CrMoV). In addition to the linear shaft range, we also offer spline shafts & nuts where torque resistance is required.

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.

QualityWhat Are Linear Bearings?

Linear bearings, also known as linear slides bearings, are different from typical bearings that facilitate circular motion. Linear slide bearings are designed to facilitate movement in a straight line and consist of two main components: a movable part and a guide rail. Linear roller bearings or linear ball bearings are commonly used and loaded onto a track that supports a surface, such as a table, enabling it to move back and forth.

ProfessionalSelect & Types of Linear Bearings?

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.

PerfectionHow Do Linear Bearings Work?

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.
