💡How do you extend service life for linear motion wheel assemblies?

Prevent early playouts by matching your mounting geometry and choosing low friction plastics.

- Swap scuffed plastic idlers for coated nylon tracks to cut drag and noise levels.

- Torque down the steel rod shafts securely so lateral shifts never damage the frame.

- Grease the stem threads lightly so pulling old hardware out stays a handy job.
