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.

Set Screw Shaft Collars
Keep these shaft collars in place by tightening their set screw into the shaft. The tip of the screw digs in for a secure hold, but will mar the shaft’s surface. For maximum holding power, make sure the set screw material is harder than your shaft material. Use these shaft collars to position and retain power transmission components such as sprockets, pulleys, and bearings. You can also use them to limit the movement of a shaft.
Carbon steel collars are strong and wear resistant. Collars with a black-oxide finish have some corrosion resistance, but only in dry environments. Their dark color can be useful for matching other parts in your system. Collars that are blue make it easy to identify metric collars at a glance. They’re tinted to match other blue metric fasteners.
303 stainless steel collars are corrosion resistant and highly machinable.
DIN 705 collars meet an international standard for shaft collar dimensions.

Clamping Vibration-Damping Precision Flexible Shaft Couplings
Designed to grip evenly around your shaft, these couplings provide more holding power than set screw couplings without marring the shaft. Tighten the clamping screws to secure. Good for precision motor and pump applications, the spider-shaped cushion reduces shock and compensates for minor shaft misalignment. Couplings allow zero backlash (no play).
A complete coupling consists of two hubs and one spider (each component sold separately). Hubs are lightweight, corrosion-resistant aluminum. Spiders are polyurethane for fair vibration damping and good chemical resistance.
