Deep groove, or single row radial, ball bearings are the most widely used bearings in all general industries. They utilize an uninterrupted raceway that makes them optimal for radial loads. NTN radial ball bearings typically come with pressed steel cages, but also offer machined brass or molded nylon material. NTN also offers bearings with locating snap rings on the outside diameter.
PRE-LUBRICATED BEARINGS
Pre-lubricated bearings have integral seals, or shields, and are packed with long-life grease. In many applications, these bearings can be used without supplementary seals, closures, or protective devices.
Shielded ball bearings are protected on one or both sides by metal shields that are fastened to the outer ring. This close clearance shield retains the lubricant and helps prevent the entrance of large, foreign matter.
Sealed ball bearings incorporate steel-reinforced rubber seals that are securely fastened to a groove on the outer ring. Contact with the inner ring provides positive sealing at all times. We also offer a variety of contact, light-contact, and non-contact seals to help you to dial in your protection while balancing your speed and torque requirements.
THERMAL MECHANICAL BALL BEARINGS (TMB): 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, 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.
- A wide range of sizes.
NTN TMB Bearings are available with all the features of a standard bearing—seals, shields, and clearances—so be sure to ask for them when looking for replacement parts.
