Overview
This high-performance thrust angular contact ball bearing is engineered specifically to support precision ball screw assemblies in demanding industrial environments. Constructed from premium-grade steel, the unit delivers exceptional rigidity and maintains accurate alignment under significant axial loads. With a bore diameter of 1.18 inches, an outside diameter of 2.44 inches, and a compact width of 0.59 inches, this component is optimized for space-constrained applications that require robust motion control. The design minimizes deflection during operation, ensuring consistent rotational accuracy and extended service life for critical machinery. Each package contains two units to facilitate simultaneous replacement or dual-support configurations.
Key Features
Precision-ground raceways ensure smooth rotation with minimal friction High axial load capacity supports heavy-duty machining operations Superior steel construction provides excellent resistance to deformation Optimized contact angle maximizes stiffness for ball screw support Compact profile fits easily into tight mechanical housings Sold in pairs to ensure balanced performance across support ends Low maintenance requirements reduce operational downtime

Applications
CNC machine tool spindle drives Industrial robotics joint actuators Precision injection molding machines Semiconductor manufacturing equipment Automated assembly line conveyors Aerospace testing rigs requiring high rigidity Medical imaging scanner positioning systems This bearing series represents a critical upgrade for facilities seeking to enhance the reliability of their linear motion systems. By utilizing advanced metallurgy and precise geometric tolerances, the component effectively handles the complex stress profiles generated by high-speed reciprocating movements. The steel material offers inherent durability against wear, while the angular contact design efficiently transfers axial forces away from the screw shaft. Engineers specifying this part can expect improved surface finish on machined parts due to reduced vibration and chatter. The inclusion of two bearings per package supports standard mounting arrangements where paired pre-loading is necessary to eliminate backlash. Whether retrofitting existing equipment or designing new automated cells, this bearing provides the structural integrity needed for long-term operational stability in harsh factory conditions.
