About Linear Bearings

About Plain Bearings

About Ball and Roller Bearings

About Shaft Collars

Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

High-Load Oil-Embedded Sleeve Bearings

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron. These bearings are also magnetic due to the high iron content.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

High-Load Food Industry Oil-Embedded Sleeve Bearings

Embedded with oil that is safe for incidental contact with food, these bearings are suitable for use in high-load applications such as bottling and filling lines in food processing plants. They are also known as Super Oilite® bearings. Startup friction releases the embedded oil onto their surface in a thin layer. Bearings are made of 863 iron-copper, which makes these bearings strong and resistant to shock loads.

Bearings with NSF H1 registered lubrication comply with NSF standards for incidental contact with food.

High-Load Ultra-Low-Friction Oil-Embedded Sleeve Bearings

Use these bearings for frequent starts and stops in high-load applications. Startup friction causes these bearings to release a thin layer of oil that contains PTFE to lubricate the bearing’s surface. All have more iron content than standard oil-embedded bearings to handle heavier loads and higher shock loads, but operate at lower speeds.

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.

Open bearings dissipate heat more efficiently than sealed bearings.

Linear Ball Bearings

Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).

Bearings with end seals keep lubricant in and dust out.

Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Fixed-alignment bearings are for use where shaft misalignment is unlikely.

Linear Bearings for Spline Shafts

With a grooved inner diameter, these bearings are designed to work with splined shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. All are for use where shaft misalignment is unlikely.

Also known as ball splines, ball bearings run with less friction than plain bearings, so they're smoother and more precise, even at high speeds. However, they don't transmit as much torque as plain bearings. They're commonly used for robotic systems and other automated applications that require complex, fast movements. Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Frictionless-Motion Mounted Linear Air Bearings

Bearing in Housing

Float bearings on air for precise, frictionless movement. Unlike traditional bearings that can wear your shaft down, these bearings are suspended using pressurized air for linear and rotary motion. Since there’s no friction, they glide smoothly and silently without wearing over time. These are self-aligning bearings, so they compensate for some shaft misalignment. They must be connected to a compressed air system.

Mounted Linear Bearings for Spline Shafts

A flanged housing with mounting holes connects these bearings directly to your system. They have a grooved inner diameter that's designed to work with spline shafts. Together, they transmit rotary power while allowing the bearing to move freely along the length of the shaft. Wide and flat, the flange is especially useful for lifting and lowering loads on vertical shafts. All are for use where shaft misalignment is unlikely.

Washdown Clamping Shaft Collars

Suitable for use in washdown applications, these plastic collars also offer good chemical resistance. They clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screw to secure.

Acetal collars have a naturally slippery surface and resist swelling when exposed to moisture.
