NU2334 (old model 32634) single row cylindrical roller bearing with separable outer ring structure. The outer ring without ribs can be freely separated from roller and inner ring assembly, convenient for installation, disassembly and maintenance. Equipped with solid brass machined cage, evenly guide each roller to reduce friction and heat generation. High density roller arrangement brings outstanding radial bearing capacity, no axial load bearing capacity. Precision ground raceway and rollers ensure low noise and stable high-speed operation. Widely matched with mining crushers, metallurgical rolling mills, heavy construction machinery, large gearboxes, cement rotary kiln transmission equipment.

• Separable outer ring design: Inner ring, roller cage assembly and outer ring can be split separately, greatly simplify shaft assembly and disassembly procedures.
• Large number of cylindrical rollers, ultra-high pure radial load bearing capacity, suitable for heavy impact working conditions.
• Machined solid brass cage, high strength and wear resistance, resistant to high temperature and impact deformation, long service life.
• Ultra-precision grinding process for raceway and roller surface, small friction coefficient, low running temperature, stable rotation.
• Can bear large radial impact load, not suitable for bearing axial force, fit unidirectional axial positioning design.
• Full GCr15 bearing steel overall quenching heat treatment, uniform hardness, good wear resistance and fatigue resistance.
• Standard interchangeable size, can directly replace same specification brand bearings without structural modification of equipment.

Q1: What is the difference between NU2334 and NJ2334?

NU2334 outer ring has no ribs, fully separable, cannot bear axial load; NJ2334 outer ring single rib, can limit single direction axial displacement.

Q2: What lubrication method is suitable for NU2334 heavy load working condition?

For long-hour heavy-load continuous operation, circulating oil lubrication is recommended; intermittent light load can adopt high-temperature lithium base grease.

Q3: Can NU2334 replace other brand same model bearings directly?

Yes, inner diameter, outer diameter and width dimensions fully unified international standard, direct interchange without
