GQZ NJ2315E.M1 Single Row Cylindrical Roller Bearing 75×160×55mm With Machined Brass Cage For Heavy Machinery Gearbox

NJ2315E.M1 is single row cylindrical roller bearing with NJ construction. E stands for enhanced optimized internal geometry for higher load rating; M1 represents solid machined brass cage. It can withstand heavy radial load and limited one-way axial load. The inner ring roller & cage assembly is separable from outer ring, simplifying mounting, disassembly and maintenance. Widely used for heavy-duty reducers, mining machinery and metallurgical transmission systems.

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

Complete dimension drawings and load data available on request.

1. E-type optimized roller arrangement, increased load capacity and outstanding anti-fatigue performance
2. NJ structure supports heavy radial load together with unidirectional axial positioning load
3. M1 machined brass cage delivers stable performance under high temperature, heavy vibration and high speed
4. Separable inner roller assembly, convenient for installation, inspection and replacement
5. Low friction, less heat generation during continuous heavy-load operation
6. Customizable options: OEM laser marking, special clearance, surface strengthening treatment
   Effectively extend service life of heavy industrial transmission assemblies.
