Spindle Bearings (Precision)
Bearings
We offer a comprehensive range of high-precision spindle bearings engineered for machine tools, CNC equipment, and other demanding industrial applications requiring exceptional accuracy and reliability. Our extensive selection includes single and double row angular contact bearings with bore sizes from 10mm to 160mm, available in various configurations including open designs, sealed versions, and ceramic hybrid options for high-speed operation. Featuring precision-ground raceways, premium steel construction, and advanced cage designs, our spindle bearings are manufactured by world-leading brands including SKF, FAG, NSK, NTN, Nachi, and UKF to meet strict P4/ABEC-7 and P2/ABEC-9 tolerance standards. Whether you need standard bearings with contact angles from 15-25 degrees, specially preloaded sets for optimal stiffness, or high-temperature variants with advanced lubrication, our technical team can help select the perfect bearing solution for your specific application requirements. All products are stocked in our UK warehouse for rapid delivery nationwide.
