NJ18/1320E 1600 mm 1320 mm 1385 mm 122 mm Frequently Asked Questions about NJ18/1320E Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each NJ18/1320E produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (1320 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing NJ18/1320E against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (1320 mm x 1600 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Yes, 100% of NJ18/1320E Single Row Cylindrical Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
To ensure optimum performance of CHG Bearing NJ18/1320E Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 1320 mm bore. For the 1600 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
