Product Overview: The 51318M Thrust Ball Bearing
The 51318M is a high-performance, single-direction thrust ball bearing, a key component in our 51300 Series of Thrust Ball Bearings. Engineered with precision dimensions of 90mm Bore Diameter, 155mm Outer Diameter, and 50mm Thickness, this bearing is specifically designed to manage high axial (thrust) loads in a single direction. A standout feature is its machined brass cage, indicated by the 'M' suffix, which provides superior strength and durability, making it suitable for applications with higher speeds and operating temperatures. The bearing's components—shaft washer, housing washer, and the ball and cage assembly—are separable, which greatly simplifies mounting and maintenance procedures.
Key Features of the 51318M Bearing
- High Axial Load Capacity: Exclusively designed to support heavy thrust loads in one direction, ensuring stability for rotating shafts.
- Machined Brass Cage: The 'M' suffix denotes a robust brass cage that offers low friction, high wear resistance, and excellent performance at high speeds.
- Separable Design: Consists of a shaft washer, a housing washer, and a ball and cage assembly that can be mounted independently for easy installation and inspection.
- Precision Manufacturing: Produced to strict industry standards to ensure dimensional accuracy and consistent, reliable operation.
- Single-Direction Operation: Optimized to handle axial forces from a single direction, making it ideal for specific load applications.
- High-Quality Materials: Constructed from premium-grade bearing steel for maximum durability and an extended service life under demanding conditions.
Common Applications
- Vertical Shafts: Essential for supporting vertical shafts in equipment such as vertical pumps, motors, and agitators.
- Machine Tool Spindles: Provides the necessary axial rigidity and precision for lathes, milling machines, and drilling equipment.
- Crane Hooks & Lifting Gear: Used in the swiveling mechanisms of crane hooks to manage heavy suspended loads.
- Industrial Gearboxes: Effectively supports the axial forces generated by helical and bevel gears.
- Rotary and Indexing Tables: Ensures smooth and precise rotation for turntables and indexing machinery under significant vertical weight.
- Extruders and Injection Molding Machines: Manages the high axial pressure generated during the manufacturing process.
Benefits of Using the 51318M Bearing
