51236 M Bearing Product Overview & Core Advantages
The 51236 M is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity and precision. This open-type bearing is designed to accommodate thrust loads in a single direction, offering a robust solution where space constraints and high load requirements converge. Manufactured from high-grade 52100 Chrome Steel for both rings and balls, it ensures exceptional durability and wear resistance. Its primary advantages include a high axial dynamic load rating of 66,600 lbf, a substantial axial static load rating of 243,000 lbf, and compliance with RoHS and REACH standards, making it a reliable and environmentally conscious choice for industrial machinery.
51236 M Bearing Model Code Explained, Specifications & Naming Convention
The model number 51236 M can be broken down to understand its technical specifications:
- 51236: Denotes the standard thrust ball bearing series with a 180 mm bore diameter.
- M: Signifies that the bearing's cage material is Stainless Steel. This offers superior strength and corrosion resistance compared to other cage materials, contributing to the bearing's overall reliability and longevity.
- Seal Type: Open (No seal or shield, allowing for higher speed capability and custom lubrication schemes).
- Load Direction: Thrust (Specifically designed to handle axial loads).
51236 M Bearing Structural Features & Performance Benefits
The design of the 51236 M thrust ball bearing translates directly into significant performance benefits:
- High Axial Load Capacity: The bearing's geometry and use of hardened 52100 Chrome Steel components enable it to support exceptionally high axial dynamic (66,600 lbf) and static (243,000 lbf) loads, making it suitable for heavy-duty applications.
- Precision and Rigidity: Manufactured with tight tolerances on the bore diameter and outside diameter, it ensures precise shaft and housing fits, leading to stable operation and minimal runout.
- Durability and Corrosion Resistance: The stainless steel cage provides excellent resistance to corrosion and can withstand higher operational stresses, enhancing the bearing's service life in challenging environments.
- High-Temperature Suitability: With an operational temperature range of -30°C to 110°C, it performs reliably in a wide array of industrial conditions.
51236 M Bearing Typical Application Areas
The 51236 M is ideally suited for machinery and equipment that experiences significant axial forces. Common application areas include:
- Heavy-Duty Industrial Gearboxes
- Vertical Pumps and Compressors
- Cranes and Hoisting Equipment
- Machine Tool Tables and other precision engineering applications
- Marine Propulsion Systems
