Montesa 315 Main Bearing

TMB BEARINGS: LIGHTER WEIGHT AND LONGER LIFE With the heightened performance of today’s machinery, bearings are being used at higher loads and speeds. As a result, the industries using this machinery demand bearings with longer-lasting, compact designs, at lighter weights and lower costs. When manufacturing these bearings, however, stringent industry requirements must be met without changing the configuration of the related parts. At NTN, we’ve met these challenges by manufacturing the Thermal Mechanical Ball Bearing (TMB). NTN TMB Bearings feature: Clean, vacuum-degassed, high-carbon chromium steel that undergoes a proprietary heat treatment to reduce crack sensitivity. High-power density that allows a smaller bearing to support higher loads. Low-weight, compact designs. A wide range of sizes. CSXX: Special radial clearance; XX is mean value in 0.001 mm units PXn: Special tolerance, from 1 onward (PX1, PX2 . . .)
