CR 51248 Single Direction Thrust Ball Bearing - 240x320x62mm - Extreme Axial Load Capacity
The CR 51248 Single Direction Thrust Ball Bearing is engineered for applications demanding superior performance under high-magnitude axial loads, particularly in heavy industrial machinery. Designed with separable components—the shaft washer, housing washer, and ball and cage assembly—this configuration facilitates easy mounting and maintenance. The bearing features precisely machined raceways and a robust brass or steel cage (depending on size and series variant) optimized to ensure smooth rolling kinematics, minimizing sliding friction and heat generation, thereby extending the operational lifespan even in severe, continuous duty cycles. This design is highly effective in supporting purely axial loads but must not be subjected to simultaneous radial loads.
Selecting the CR 51248 guarantees reliability and adherence to strict dimensional tolerances essential for high-precision installations like large crane hooks, vertical shafts in heavy gearboxes, and large lathe tailstocks. As a CR branded component, it is manufactured using high-quality, high-cleanliness steel to resist fatigue and deliver consistent performance. Its capacity for handling extremely heavy static and dynamic axial forces makes it an indispensable component for reducing downtime and total cost of ownership in critical operations where bearing failure is simply not an option. For optimal service life, ensure proper lubrication and alignment during installation.
Key Features
Separable Design: Shaft washer, housing washer, and ball assembly can be mounted independently, simplifying large-scale installation and replacement procedures.
Exceptional Axial Load Handling: Designed specifically to accommodate high axial forces in one direction, essential for vertical shaft support.
Precision Ground Raceways: Optimized raceway curvature ensures smooth running and minimizes friction, enhancing energy efficiency and reducing heat buildup.
CR Quality Construction: Manufactured from high-purity, vacuum-degassed steel for maximum fatigue resistance and extended operational life.
Robust Cage Material: Utilizes high-strength pressed steel or machined brass cage for reliable ball retention under high speeds and heavy industrial shock loads.
