GQZ NJ324E.M1 Single Row Cylindrical Roller Bearing 120×260×55mm With Solid Brass Cage For Heavy Load Reducers

NJ324E.M1 is single row cylindrical roller bearing of NJ design. E stands for enhanced optimized internal geometry to achieve higher dynamic load rating; M1 refers to solid machined brass cage. It can withstand heavy radial load and limited one-way axial load. The inner ring assembly including rollers and cage is separable from outer ring, bringing great convenience for installation, disassembly and maintenance. Widely used in heavy-duty reducers, mining equipment, metallurgical machinery and large industrial transmission systems.

1. E-type optimized roller layout, larger load rating and excellent fatigue resistance under continuous heavy load
2. NJ structural design: carries heavy radial load and realizes unidirectional axial positioning
3. M1 machined brass cage runs stably under high temperature, vibration and medium-high speed working conditions
4. Separable inner roller assembly, easy for independent mounting, inspection and component replacement
5. Optimized surface finish reduces friction heat and prolong service life under long-time operation
6. Customizable options: OEM laser marking, special clearance, anti-rust strengthening treatment
   Greatly reduce failure risk for heavy industrial transmission assemblies.
