High Light NJ211E.M1 cylindrical roller bearing brass cage55x100x21mm cylindrical roller bearing solid cagesingle row roller bearing one-way axial shafts
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
  1. NJ single rib outer ring design realizes reliable one-way axial positioning, avoids shaft single-direction movement
  2. E-type optimized roller surface improves contact uniformity, stronger shock resistance and higher load capacity
  3. M1 solid brass cage owns high rigidity and heat resistance, not easy to deform under low-speed heavy load
  4. Separable inner and outer ring allows separate installation, convenient disassembly and parts replacement
  5. Low friction rolling design supports stable medium-high speed running with low noise
  6. Standard ISO metric size, fully interchangeable with same-spec cylindrical roller bearings
  7. 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. Appliion 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
