Bearing Information

BGA – A 52MM (6205) Bearing used in high-speed applications

BGAS – A 52MM (6205) Bearing used in low to moderate speed applications where high contamination is present

BGF – A 52MM Collar locking bearing used in low to moderate speed applications where moderate contamination is present (used only for 1” shaft mounts)

BGBS – A 40MM (6203) Bearing used in low to moderate speed applications where high contamination is present

BGB – A 40MM (6203) Bearing used in high-speed applications

NB21 – A Fixed Bearing used in underwater applications

Auxiliary Seal Information

NRT – An auxiliary bearing seal that provides excellent protection in high-contamination areas to greatly improve bearing life. The NRT seal has a low friction coefficient, providing low bearing drag.
