Trend B35GRS Bearing rubber shielded 15mm bore
Bearings are shielded for an improved protection. Shielded to prevent penetration of dust & grease. They?re packed for life.
Bearings should not be cleaned with solvent or lubricated because this will dissolve the grease causing premature bearing failure.
To clean simply scrape off any resin build-up.
Always check the tension of the fixing screw before using cutter.
