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.
Bearings with a black-oxide steel ring have some corrosion resistance.
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.

Ultra-Thin Ball Bearings
These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.
Open bearings dissipate heat more efficiently than shielded bearings.

Oil-Embedded Sleeve Bearings
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.

Swivel Joints
Also known as spherical bearings, swivel joints support angular misalignment. Press them into a hole or housing where a ball joint rod end won’t fit. They need to be lubricated when first installed and periodically after that. Apply any type of bearing grease to the ball, and rotate it to work it into the races.
Sealed joints keep grease in and contaminants out.
For technical drawings and 3-D models, click on a part number.
Extended-Life Swivel Joints
Specially designed lubrication channels and integral seals allow these joints to last up to three times longer than other swivel joints. Also known as spherical bearings, they support angular misalignment. Press into a hole or housing where a ball joint rod end won’t fit. All have seals to keep grease in and contaminants out. Joints come greased and can be lubricated through a hole in the housing without removing the load.

Self-Adjusting Spring Bushings
A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit. Made of spring steel, they flex under stress and shock and can handle oscillating or slow rotational motion.

Taper-Lock Bushings
Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

Wide-Rim Ring Shims
Also known as machinery bushings, these shims have an oversized OD to create a larger bearing surface for reduced wear between moving parts. Use them to precisely align, level, and adjust spacing on shafts and machinery.
Stainless steel shims are more corrosion resistant than carbon steel shims.
Carbon steel shims have excellent strength and can be welded.
A zinc-plated finish adds a layer of corrosion resistance.
