These rolling bearings with integral seals protect against contaminants and retain lubricant. Pre-lubricated “greased for life” versions offer additional performance and service benefits by avoiding problems with mixing greases. The family of integral seals includes low-friction and contact types manufactured from nitrile rubber and selected based on operating speed and friction requirements. All are engineered to promote lubricant retention and protect against potential external contaminant damage from incompatible mineral oil-based lubricants, fuels, other oils and greases, dust, and water.
