51200 Bearing Product Overview & Core Advantages
The 51200 is a metric thrust ball bearing engineered for applications requiring high-precision axial load support. Its design is optimized to accommodate thrust loads in a single direction, making it an ideal component for compact assemblies where space is at a premium. Manufactured from 52100 Chrome Steel for both rings and balls, it delivers excellent durability and wear resistance. The bearing features an open seal type, facilitating easy re-lubrication if required in specific service conditions. Its primary advantages include a high axial dynamic load rating of 2858 lbf, a compact cross-section, and compliance with RoHS and REACH environmental standards, ensuring suitability for modern industrial applications.
51200 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51200 | Basic model number indicating a metric, single-direction thrust ball bearing with a 10mm bore. |
| Open (Seal Type) | No integral seals or shields. This allows for higher limiting speeds and custom lubrication schemes but requires a clean operating environment. |
51200 Bearing Structural Features & Performance Benefits
- High Load Capacity: The bearing is designed specifically to handle significant axial thrust loads, with a static load rating of 4185 lbf, providing robust performance in demanding applications.
- Precision Engineering: Tight dimensional tolerances on the bore diameter and outside diameter ensure precise fit and reliable operation, contributing to the overall system's accuracy.
- High-Speed Capability: The use of a stainless steel cage and the open design contribute to a high limiting speed of 11,000 rpm, making it suitable for high-rotation equipment.
- Material Integrity: Components made from 52100 Chrome Steel offer high hardness and resistance to fatigue, while the stainless steel cage provides excellent corrosion resistance and strength.
- Compact and Lightweight: With a width of only 11mm and a weight of just 0.03 kg, it is an excellent choice for applications where minimizing size and mass is critical.
