Product Overview: The 51256M Thrust Ball Bearing
The 51256M is a high-capacity, single-direction thrust ball bearing engineered to manage substantial axial loads in one direction. As a key component in our 51200 Series of Thrust Ball Bearings, it is designed with standard dimensions of 280mm Bore Diameter, 380mm Outer Diameter, and 85mm Thickness. This bearing's separable design, consisting of a shaft washer, a housing washer, and a ball and cage assembly, simplifies mounting and maintenance procedures. The 'M' suffix signifies a machined brass cage, which provides superior strength and durability, making it suitable for demanding industrial applications requiring high precision and reliability.
Key Features of the 51256M Bearing
- Single-Direction Axial Load: Specifically designed to accommodate heavy axial loads and locate a shaft axially in one direction.
- Separable Components: The shaft washer, housing washer, and ball/cage assembly can be mounted separately, facilitating easy installation and inspection.
- Machined Brass Cage (M): Offers high strength, excellent wear resistance, and stability at higher speeds and temperatures compared to standard steel cages.
- High-Quality Materials: Manufactured from premium-grade bearing steel to ensure a long service life and consistent performance under rigorous conditions.
- Precision Engineering: Produced to strict tolerances, ensuring smooth and efficient operation with minimal friction.
- Flat Seat Housing Washer: Features a flat seating surface, requiring a simple, flat support surface for mounting.
Common Applications
- Vertical Shafts: Ideal for supporting vertical rotating shafts in equipment like pumps, turbines, and generators.
- Industrial Gearboxes: Used to manage axial forces generated by helical and bevel gears.
- Crane Hooks and Swivels: Provides reliable support for heavy rotating loads in lifting and material handling equipment.
- Machine Tool Spindles: Ensures precision and rigidity in applications such as lathes, milling machines, and drilling presses.
- Rotating and Indexing Tables: Delivers smooth rotational support for high-precision positioning systems.
- Screw Jacks: Essential for converting rotational motion into linear motion while supporting heavy axial loads.
- Extruders and Injection Molding Machines: Withstands the high thrust forces generated during material processing.
