Timken 395-90036 Precision Taper Bearing Assembly

Timken 395-90036 is a matched precision tapered roller bearing assembly engineered for high-accuracy spindle applications in CNC machines and other precision machine tools. This single-row matched set provides controlled preload and excellent radial and axial stiffness, making it ideal for CNC milling machines, precision grinders, lathes, and spindle assemblies where low runout and rigid shaft positioning are critical. The assembly combines cone part 395 with assembly number 90036, and is a precision matched design from Timken, with factory preset preload to maintain consistent performance. Construction features include through-hardened bearing steel and a precision steel cage, designed for lubrication with oil or grease. Mounting is a precision matched assembly configured for controlled preload, ensuring reliable performance in high-speed, high-precision spindle environments. Common replacements include SKF 395-90036, NTN 395-90036, and KOYO 395-90036, reflecting its role in spares and retrofits for machine tool upgrades. This bearing assembly is used in precision spindle and machine tool systems that require high rigidity, accurate shaft positioning, and extended bearing life, supporting operations in CNC machining centers, precision lathes, milling and grinding machines, and other high-precision industrial equipment.
