Deep groove, or single row radial, ball bearings are the most
widely used bearings. They utilize an uninterrupted raceway that makes them
optimal for radial loads .This design permits precision tolerance, even at
high-speed operation.
NTN ball bearings use standard cages of pressed steel, as well as machined,
brass cages for high-speed applications. NTN also offers bearings with locating
snap rings.
PRELUBRICATED
BEARINGS
Prelubricated bearings have integral seals, or shields, which are packed with
long-life grease. In many applications, these bearings can be used without
supplementary seals, closures, or protective devices. This design also offers
the lowest possible manufacturing costs to the end user.
Shielded ball bearings are protected on one or both sides by metal shields that
are fastened to the outer ring. This close clearance labyrinth seal retains the
lubricant and prevents the entrance of 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.
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.
