Slider Shielded Ball Brg

The Slider Shielded Ball Brg from Winters is a precision lower shaft bearing engineered for quick-change tooling systems. This steel bearing assembly is designed for operators and machinists who require reliable, repeatable performance in high-rotation applications where shaft alignment and durability are critical. Whether integrated into lathe chucks, spindle systems, or production machinery, this bearing delivers the precision fit that professional-grade quick-change platforms demand.

The shielded design protects internal ball races from contamination and debris, extending bearing life in shop environments where coolant, chips, and dust are present. Steel construction ensures high load capacity and resistance to thermal stress, making it suitable for sustained spindle speeds and intermittent heavy loads. The slider mechanism allows smooth engagement and disengagement with mating quick-change components, reducing wear on indexing surfaces and maintaining concentricity across multiple tool changes. Compact dimensions (3.4 x 0.95 x 4.5 inches) allow integration into tight spindle or chuck assemblies without sacrificing rigidity.

This bearing is ideal for machinists, tool-and-die professionals, and production shops operating Winters quick-change systems or compatible spindle platforms. Replacement or upgrade applications benefit from the OEM-matched fit and performance specifications. Installation requires alignment with the lower shaft housing; refer to your equipment's manual for torque and positioning guidelines. Weighing 0.98 lbs, it integrates seamlessly into existing Winters quick-change assemblies, ensuring minimal downtime during changeover.
