 Products  description

SKF Explorer class QJ 308 N2MA Four-point contact ball bearings are made from extremely clean steel that has undergone a unique SKF heat treatment to provide outstanding strength, stiffness and wear-resistance. An improved brass cage is lighter, to reduce inertia forces. It also provides better ball guidance. A PEEK cage, which combines the advantages of light-weight plastic with the durability and performance of a brass cage is also available. A shoulder recess on the inner ring provides additional lubrication improvements, and a redesigned raceway shoulder transition makes the bearings capable of carrying increased thrust loads.
