Thin-Profile Crossed-Roller Bearings
For a more compact machine, these bearings have thinner inner and outer rings than high-load crossed-roller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

High-Load Dry-Running Thrust Bearings
A steel backing adds strength to these slippery PTFE 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.

Lubrication-Free Swivel Joints
A slippery PTFE liner reduces friction without the oily mess. Also known as spherical bearings, they support angular misalignment. Press them into a hole or housing where a ball joint rod end won’t fit.
