- Bore Diameter (d): 100 mm
- Outer Diameter (D): 180 mm
- Width (B): 46 mm
- 정격 부하:
- 동적 정격 하중 (Cr): Approximately 490 kN (exact value depends on manufacturer standards). This high rating signifies its ability to handle severe dynamic radial loads over long service life.
- 정적 정격 하중 (코르): Approximately 550 kN, indicating excellent resistance to heavy static or slow-oscillation loads.
- Speed Ratings: Suitable for moderate to high rotational speeds.
- Material & Construction: Rings and rollers are manufactured from vacuum-degassed, high-carbon chromium bearing steel (SAE 52100), through-hardened for uniform hardness and deep stress resistance. Precision grinding ensures optimal spherical raceway and roller profiles.
