211/C3 Bearing Product Overview & Core Advantages
The 211/C3 is a single row deep groove ball bearing engineered for high-performance radial load applications. Designed with open construction and manufactured to ABEC 1 | ISO P0 precision standards, it delivers reliable operation in demanding industrial environments. Its chrome steel construction provides excellent durability and wear resistance. The bearing features a liberal C3 radial internal clearance, making it particularly suitable for applications with thermal expansion, heavy loads, or where interference fits are used, ensuring stable performance under varying operational conditions.
211/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 211 | Standard bearing series designation with 55mm bore, 100mm OD, 21mm width |
| C3 | Radial internal clearance greater than normal group, suitable for applications with thermal expansion or heavy interference fits |
| Open | No seals or shields, allowing for higher speed capability and custom lubrication options |
211/C3 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient handling of radial loads while accommodating moderate axial loads in both directions, providing versatile load capacity.
Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with tight dimensional control (bore/OD tolerance: -0.015mm to 0), ensuring consistent performance and easy installation.
Enhanced Thermal Performance: The C3 clearance accommodates thermal expansion during operation, preventing binding and maintaining smooth rotation under temperature variations from -30°C to 120°C.
High-Speed Capability: With a limiting speed of 7,000 rpm and open design, this bearing offers excellent high-speed performance while allowing for optimal lubrication management.
Robust Load Capacity: Features dynamic load rating of 10,881 lbf and static load rating of 9,892 lbf, providing reliable operation under significant radial stresses.
