Benefits of Blue Rubber Seals

Compared with metal-shielded types, the blue rubber seals keep grit out and make routine servicing simpler. This sealing helps the bearing races stay cleaner so parts last longer between overhauls.

Care and Service Notes

Inspect bearings after heavy impacts or rough runs and top up lubrication with a low-viscosity oil to preserve free spin. Small periodic checks and light lubrication will maintain smooth rolling and reliable performance.
