52315 Bearing Product Overview & Core Advantages
The 52315 metric thrust ball bearing is engineered for high-precision axial load applications requiring exceptional reliability. Designed exclusively for thrust load direction, this bearing delivers superior performance in demanding environments. Its open seal type allows for optimal lubrication access while maintaining structural integrity. Manufactured with chrome steel rings and balls combined with a stainless steel cage, this bearing offers excellent durability and corrosion resistance. The precise dimensional tolerances ensure consistent performance in critical applications where axial load capacity and positional accuracy are paramount.
52315 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Impact |
|---|---|---|
| 52 | Thrust Ball Bearing Series | Standard design for pure axial loads |
| 315 | Size designation (60mm bore × 135mm OD) | Determines bearing dimensions and load capacity |
| Open Seal | No integrated seals | Allows custom lubrication solutions and higher speed capability |
52315 Bearing Structural Features & Performance Benefits
Enhanced Load Capacity: With an axial dynamic load rating of 36,675 lbf and axial static load rating of 87,750 lbf, this bearing is optimized for heavy thrust applications. The precision-ground raceways and high-quality chrome steel construction ensure reliable performance under significant axial forces.
High-Speed Capability: The stainless steel cage provides excellent strength and corrosion resistance, contributing to stable operation at limiting speeds up to 1,800 rpm. The open design facilitates efficient lubrication distribution for reduced friction and heat generation.
Precision Engineering: Tight dimensional tolerances on the bore diameter (-0.015mm to 0) and outside diameter (-0.025mm to 0) ensure precise fitment and alignment. The specific housing washer inner diameter of 77mm and carefully controlled chamfer sizes (1.5mm housing washer, 1mm shaft washer) prevent stress concentration and facilitate proper installation.
Temperature Stability: Operating temperature range of -30°C to 110°C ensures reliable performance across diverse environmental conditions, while the 4.8kg weight reflects the robust construction suitable for industrial applications.
