51264 F Bearing Product Overview & Core Advantages
The 51264 F is a metric thrust ball bearing engineered for applications demanding high axial load capacity and precision. Its design is optimized to accommodate heavy thrust loads in a single direction while maintaining stable operation. Manufactured from high-grade 52100 Chrome Steel for both rings and balls, and featuring a Stainless Steel cage, this bearing offers exceptional durability and corrosion resistance. Its open seal type allows for easy re-lubrication, making it suitable for high-reliability industrial environments where robust axial dynamic load rating and axial static load rating are critical.
51264 F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 51264 | Basic model number denoting a thrust ball bearing with a 320 mm bore and 440 mm outside diameter. |
| F | Suffix indicating a machined brass cage (in this context, the provided specification lists a Stainless Steel cage, confirming a high-strength, precision-machined retainer). |
| (Implied: Open) | The open seal type signifies no integral seals or shields, allowing for high-speed capability and custom lubrication schemes. |
51264 F Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: Engineered with a 52100 Chrome Steel construction, this bearing is designed to withstand extreme axial dynamic load ratings of 128,700 lbf and axial static load ratings of 675,000 lbf, making it ideal for heavy-duty thrust applications.
- Precision & Stability: Features tight dimensional tolerances on the bore diameter and outside diameter, ensuring precise fit and stable operation under load. The stainless steel cage provides superior guidance for the balls, reducing friction and wear.
- Robust Construction: The use of hardened Chrome Steel for all rolling components ensures long service life and resistance to deformation under high stress.
- Operational Versatility: With a temperature range of -30°C to 110°C and compliance with ROHS and REACH standards, it is suitable for a wide array of industrial environments.
51264 F Bearing Typical Application Areas
This thrust ball bearing is specifically designed for machinery and systems that require management of substantial axial forces. Key applications include:
- Heavy-Duty Thrust Applications: Such as large vertical pumps, industrial gearboxes, and crane hooks.
- Power Transmission Systems: Including screw down systems in metal rolling mills and large worm gear reducers.
- Industrial Machinery: Found in applications like hydraulic presses, injection molding machines, and large valves where high unidirectional thrust loads are present.
