| Suffix Code | Technical Meaning |
|---|---|
| CEGA | Enhanced internal geometry and optimized contact angle for superior high-speed performance and load capacity. |
| P4A | Indicates a super-precision tolerance class with extremely tight dimensional and running accuracy tolerances. |
| Sealed | Integrated seals to retain lubrication and protect against contamination, enhancing service life. |
S7010 CEGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row design, combined with P4A tolerance class and a 15° contact angle, provides excellent dimensional stability and high rigidity for precise shaft positioning.
- Superior Load Capacity: Engineered to handle combined radial and axial loads efficiently. The dynamic load rating of 3510 lbf and static load rating of 2385 lbf ensure reliable performance under demanding conditions.
- Optimized High-Speed Performance: The phenolic resin cage offers low friction and high strength, contributing to the high limiting speed of 34,000 rpm. The pre-filled high-performance grease ensures stable lubrication at high rotational speeds.
- Long Service Life & Reliability: Constructed from chrome steel for rings and balls, providing high wear resistance. The sealed design and quality grease offer protection across a wide temperature range from -30°C to 110°C.
