The ball-bushing
alternative that
doesn't need grease.

Simplicity® self-lubricating linear bearings are a true drop-in replacement for recirculating ball bushings — same envelope, same shaft, none of the lubrication. Run cleaner, quieter, and longer in the environments where ball bushings fail first.

Why engineers spec Simplicity

Self-lubricating polymer riding on hardened linear shaft — engineered for the duty cycles, environments, and maintenance budgets where ball technology breaks down.

/ 01

Zero lubrication

No grease fittings, no relube schedule. Eliminate a recurring line item from your service plan.

/ 02

Drop-in replacement

Same OD, same length, same mounting as standard ball bushings. Swap without redesigning the carriage.

/ 03

Wash-down + clean-room

FDA-compliant material options handle food-grade cleaning protocols and clean-room particle limits.

/ 04

Quiet running

Polymer-on-steel contact eliminates the recirculating-ball noise signature. Friendly to medical and lab environments.
