Before each RIGIA crossed roller bearing leaves the factory, its surface(inside & outside) and raceway will be coated with anti-rust and lubricative grease, then covered with one layer of plastic film and one layer of woven belt. For precision bearings, polyethylene foamed plastic belt need to be added between two layers mentioned above, in order to protect bearings during transportation. The outer packing is customized plywood case or carton box.
RIGIA "BRSZC" crossed roller bearings have been through rust-proof treatment before shippment. Under normal maintaining conditions, RIGIA bearing provide a 12 months' guarantee against rust. If bearings storage time exceed 12 months, we suggest customer to re-clean and do anti-rust treatment.
Bearings should be placed at dry, ventilated, and flat sites, while stored in isolation from chemicals or other corrosive goods.
