Set Screw Collar Ball Bearings
Slip these bearings onto a shaft and secure with the included set screws, no special tools required. All have an extended inner ring for additional shaft support.
Sealed bearings block out dust and other contaminants better than shielded bearings.
Bearings with a retaining ring have a removable retaining ring that holds the bearing inside a housing.

One-Piece Thrust Ball Bearings
In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

Thrust Ball Bearings for Shaft Ends
Use these bearings as miniature high-precision turntables. They have a unique design that allows your shaft to sit on top of the bearing rather than being inserted through it. Bearings can be bonded to a mounting plate or press-fit into a hole.

Oil-Embedded Sleeve Bearings
Startup friction causes these 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 Dry-Running Sleeve Bearings
Bearings with 17-4
PH Stainless Steel Shell
A metal shell adds strength.
PTFE bearings with 17-4 PH stainless steel shell are for use in oscillating rotation and have the highest load capacity of any sleeve bearing we offer. They handle shock loads and are chemical resistant.
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-Temperature Dry-Running Sleeve Bearings
Graphite provides a layer of dry lubrication that operates in high-temperature environments.
Graphalloy bearings perform at extreme temperatures and under water. They are electrically conductive and wear resistant.

High-Load Ultra-Low-Friction Oil-Embedded Thrust Bearings
Handle heavy loads that frequently start and stop along shafts—these bearings contain extra iron and slippery PTFE lubricant. Startup friction causes a thin layer of PTFE to release onto the surface. Thanks to their high iron content, they also resist failing if their load suddenly and drastically increases, but they won’t run as fast as standard bearings. They’re thrust bearings, which means they support loads parallel to the shaft.

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.

Quick-Disconnect (QD) Bushings
The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
