NJ211E.M1 cylindrical roller bearing brass cage

55x100x21mm cylindrical roller bearing solid cage

single row roller bearing one-way axial shafts

Product Description

1. Product Overview

NJ211E.M1 is single row separable cylindrical roller bearing with E optimized reinforced rollers and M1 solid machined brass cage. It features single ribs on outer ring, enabling one-way axial positioning to limit shaft single-side displacement. Separable inner and outer ring simplifies assembly and maintenance; line contact roller structure provides outstanding radial load capacity, widely used for heavy-load transmission shafts requiring unidirectional axial fixation.

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

3. Core Advantages

NJ single rib outer ring design realizes reliable one-way axial positioning, avoids shaft single-direction movement
E-type optimized roller surface improves contact uniformity, stronger shock resistance and higher load capacity
M1 solid brass cage owns high rigidity and heat resistance, not easy to deform under low-speed heavy load
Separable inner and outer ring allows separate installation, convenient disassembly and parts replacement
Low friction rolling design supports stable medium-high speed running with low noise
Standard ISO metric size, fully interchangeable with same-spec cylindrical roller bearings
Customizable options: special clearance grades, OEM laser marking, high-temperature grease, dust shields
Effectively reduce roller abrasion, restrict single-side axial drift and extend service life of transmission equipment.

4. Application Scenarios

Industrial gearboxes, reducers and heavy transmission housings
Driving motors, generator shafts and pump rotary assemblies
Metallurgical, mining conveying and vibratory machinery
Machine tool spindles, textile printing roller transmission parts
Construction and agricultural machinery power output shafts
General industrial equipment needing heavy radial load and one-way axial location
