Outdoor as well as mild chemical environments are no problem for these bearings. They have stainless steel balls for corrosion resistance. Mount them on a support rail shaft for applications requiring maximum rigidity. They are self-aligning to compensate for shaft misalignment.

Virtually maintenance free, these bearings have slippery, chemical-resistant liners that don't require added lubrication. Mount them on a support rail shaft for applications requiring maximum rigidity.

Bearings with 0.0005" shaft clearance are best for precision applications. Bearings with 0.001" or 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.

Self Aligning—Bearings compensate for shaft misalignment.

Frelon liners are stronger and more wear resistant than PTFE liners.

Keep your ball screw spinning without the ball nut damaging your system—a clutch-like collar inside the ball nut prevents it from travelling past the stop pins. Install the included stop pins anywhere along the length of the ball screw by drilling a hole in the valley of the threads (also known as the root) and pressing in the stop pin. When the collar meets the stop pin, the ball nut disengages from the threads and begins to idle. To start the ball nut travelling again, spin the ball screw in the opposite direction. All components are black-oxide steel and have mild corrosion resistance. To ensure compatibility, select components that have the same thread size. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.

Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.

A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end. Also known as diamond lead screws, they're sometimes used to guide cable and wire as it's spooled on a reel.

Replace worn or damaged wheel bearings to keep your equipment rolling. Use flanged bearings and ball bearings in pairs. Change the axle diameter with wheel reducer bushings (sold separately).

Note: Not for use in towing applications.

For impact-resistant tapered roller bearings, as well as other bearing materials and sizes, please see Ball and Roller Bearings and Sleeve Bearings. Roller bearings provide smooth rolling.

Retaining washers hold roller bearings in place.

Reduce the inside diameter of a bearing to fit a particular axle size. Also known as spanner bushings, they also reduce wear on the axle when used in plain bores and with straight roller bearings. All have a hole for lubrication.

Washers slide over the bushing and add 3/32" to the hub length of your wheel. Multiple washers can be used to match the length of the bushing.
