GQZ NJ220 EM1 C3 Cylindrical Roller Bearing 100×180×34mm With Machined Brass Cage For Heavy Gear Units

NJ220 EM1 C3 is single row cylindrical roller bearing of NJ type structure. NJ means inner ring with single rib, outer ring without ribs; EM1 represents robust solid machined brass cage. C3 stands for increased radial internal clearance. This bearing can withstand heavy radial load and limited one-way axial load. The roller assembly can be separated from inner ring for convenient installation, inspection and maintenance. Widely used for heavy-duty gearboxes, mining conveyors, metallurgical equipment and construction machinery transmission assemblies.

Formal quotation will be sent within 24 hours upon your inquiry.

Complete dimension drawings and load data available on request.

1. NJ structural design, supports heavy radial load and limited unidirectional axial positioning load
2. EM1 machined brass cage offers high temperature resistance, stable performance under sustained heavy loads
3. C3 extra clearance provides thermal expansion allowance for continuously operating equipment
4. Separable roller assembly simplifies disassembly and on-site maintenance work
5. High rigidity and strong impact resistance, suitable for alternating heavy load industrial conditions
6. Customizable options: OEM laser marking, special clearance grades, surface strengthening treatment

Effectively reduce failure risk for heavy load power transmission systems.

• Large heavy-duty industrial gearboxes and speed reducers
• Mining belt conveyor drive assemblies
• Metallurgical plant roller supporting shafts
• Water pump, compressor heavy load bearing positions
• Construction machinery and heavy vehicle transmission parts
• Medium speed equipment requiring high radial rigidity and one-way axial location
