NTN Bearing TMB306 Single Row Thermal Mechanical Radial Ball Bearing, Normal Clearance, Steel Cage, 30 mm Bore, 72 mm OD, 19 mm Width, Open

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. NTN has met these challenges by manufacturing the Thermal Mechanical Ball Bearing (TMB). NTN TMB Bearings feature: (1) Clean, vacuum-degassed, high-carbon chromium steel that undergoes a proprietary heat treatment to reduce crack sensitivity, (2) High-power density that allows a smaller bearing to support higher loads, and (3) Low-weight compact designs.NTN is one of the three largest bearing companies in the world with more than ninety years of manufacturing expertise in ball bearings.

• Lighter weight and longer lasting compact design
• Heat treated high-carbon chromium steel to reduce crack sensitivity
• High-power density allows higher loads
• Open bearing for lubrication applied in place
• CN (normal) radial internal clearance for applications that do not involve thermal expansion or atypical precision
