1PCS NJ2210EM 50X90X23 42510 NJ2210ECML NJ2210EM1 NJ2210 P6 ABEC3 Cylindrical roller bearings Single row This listing describes a singlerow cylindrical roller bearing with a 50 mm bore, 90 mm outer diameter, and 23 mm overall width. The bearing is part of the NJ2210E family and is offered in multiple variant codes for different mounting or lubrication configurations, including NJ2210EM, NJ2210ECML, and NJ2210EM1. It is specified as ABEC3 (P6) precision, and is also catalogued as 42510 and as NJ2210. Key benefits radial load capacity: Cylindrical roller bearings are designed to support substantial radial loads in a compact, singlerow form. Precision tolerance: ABEC3 (P6) precision class provides reliable, consistent rotation and performance suitable for precision machinery. Compact, standardized size: With a bore of 50 mm, outer diameter of 90 mm, and width of 23 mm, this bearing fits many standard housings and shaft arrangements. Variant options for mounting and lubrication needs: The variants NJ2210EM, NJ2210ECML, and NJ2210EM1 indicate different cage designs or configurations to suit specific installation requirements. Broad compatibility: Suitable for machinery and equipment that require a 50x90x23 bearing and the corresponding radial support. Key attributes Bearing type: Cylindrical roller bearing, single row Models/variants: NJ2210EM, NJ2210ECML, NJ2210EM1, NJ2210 (also listed as 42510) Dimensions: bore 50 mm, outer diameter 90 mm, width 23 mm Precision: ABEC3 (P6) Configuration: Singlerow cylindrical roller bearing Applications: General industrial machinery requiring robust radial support Applications and use cases Machine tool spindles: Provide stable radial support for precision spindle assemblies in milling or grinding equipment. Gearboxes and drive shafts: Serve as the main radial support within reducers or conveyor drive systems, where rigid mounting and load handling are essential. Industrial machinery and equipment: Suitable for pumps, fans, and other heavyduty machines requiring reliable radial bearing performance in a compact form. Notes Variants listed (EM, ECML, EM1) reflect different design configurations within the NJ2210 family; select according to mounting, cage, or lubrication requirements as applicable to your equipment. Ensure proper installation with compatible housings and shafts designed for 50x90x23 bearings, and verify tolerance, clearance, and lubrication considerations per equipment specifications.
