Product Description
1. Product Overview
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.
