HJ Series Heavy Duty Caged Needle Bearings

These bearings meet Military Standard MS 51961. Use a loose fit for the outer ring when the housing is stationary and a tight fit when the housing rotates. For low radial clearance in oscillating applications, consult Rainbow engineering for mounting dimensions. We offer open and sealed HJ Heavy Duty Needle Roller Bearings; sealed types have a -2RS suffix. See the Heavy Duty Needle Bearing Inner Ring Section for the appropriate inner ring.
