51113 Bearing Product Overview & Core Advantages
The 51113 thrust ball bearing is a metric single-direction thrust bearing engineered for applications requiring high axial load capacity in one direction. Manufactured from 52100 Chrome Steel for both rings and balls, it delivers exceptional durability and wear resistance. Its compact design, featuring a 18 mm width, makes it ideal for space-constrained assemblies where reliable thrust load handling is paramount. This bearing is characterized by its high axial static load rating and is compliant with RoHS and REACH environmental standards.
51113 Bearing Model Code Explained, Specifications & Naming Convention
The model number 51113 is decoded as follows:
- 51113: Indicates a metric thrust ball bearing series with a 65 mm bore diameter and 90 mm outside diameter.
- Open (Seal type): The bearing is supplied without seals or shields, allowing for higher limiting speeds and facilitating custom lubrication schemes.
51113 Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The robust construction, utilizing 52100 Chrome Steel components, enables a high axial static load rating of 24,300 lbf and a dynamic rating of 8,482 lbf, making it suitable for demanding thrust applications.
- Precision & Stability: Tight dimensional tolerances on the bore diameter and outside diameter ensure precise fit and stable operation under load.
- High-Speed Capability: The open design and stainless steel cage contribute to a limiting speed of 4,800 rpm, suitable for various high-speed machinery.
- Corrosion Resistant Cage: The stainless steel cage provides excellent corrosion resistance and ensures cage integrity at high rotational speeds.
