Core Official Features (NSK Global Catalog)
- 4-Row Gothic Arch Grooves: 4-point contact structure provides equal load capacity in radial, reverse-radial, and lateral directions, with strong resistance to moment loads.
- 50° Optimized Contact Angle: Enhances vertical load capacity and rigidity, suitable for medium-duty applications requiring stable precision.
- High Impact Resistance: The bottom groove is offset; top two rows handle normal loads, while the bottom rows engage under high impact, ensuring reliable performance under shock.
- Self-Aligning Capability: Absorbs minor installation surface errors, reducing assembly effort and maintaining consistent accuracy.
- K1™ Maintenance-Free Lubrication: Compatible with NSK K1 lubrication units for long-term, low-maintenance operation.
- Interchangeable Dimensions: Conforms to global dimensional standards, enabling easy replacement and system integration with legacy series.
- Wide Option Range: Available in multiple accuracy and preload grades to suit diverse application needs.
