Spindle Bearings

1. Double Contact Seals (2RSD)

2RSD indicates double-lip rubber seals that effectively prevent contaminant ingress, extending bearing life in harsh operating conditions.

2. High Load Capacity

Basic dynamic load rating (Cr): 26.5 kN, static load rating (Cor): 20 kN, suitable for high-load precision applications.

3.Special Cage (T-Type Phenolic Resin)

T-type cage (laminated textile phenolic resin) features high-temperature resistance (100°C) and low friction characteristics, suitable for high-speed operation.

4.Optimized Contact Angle Design (25°)

25° contact angle (suffix E) provides higher axial stiffness and radial load capacity, suitable for combined cutting and high-speed machining.

5. Light Preload (UL)

UL suffix indicates bearings with light preload, reducing clearance and increasing rigidity, suitable for precision matched mounting (O or X arrangements).

6.  Ultra-High Precision (P4S Grade)

Compliant with ISO P4S standard (P4 dimensional accuracy, P2 running accuracy), ensuring stability and low vibration during high-speed operation.

Ideal for high-speed, high-rigidity applications such as CNC machining center spindles.

7. High-Speed Performance

Grease lubrication limit speed: 17,000 r/min, oil lubrication can achieve higher speeds (some data indicates maximum speed up to 28,000 r/min).
