NTN ball bearings are available in sizes ranging from 10 mm to 320 mm outside diameters and in a wide variety of configurations of seals, shields, lubricants, internal clearances, and cage designs. With more than ninety years of manufacturing expertise in ball bearings, NTN offers one of the industry’s widest arrays of products to fit your application.

NTN Deep Groove Ball Bearings

NTN 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.

NTN Deep Groove Ball BearingsNTN Prelubricated Deep Groove Ball 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.

NTN TMB Deep Groove Ball Bearings

NTN TMB Bearings feature a lighter Weight and longer Life— Thermal Mechanical Ball Bearing (TMB) features: 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.

NTN Angular Contact Ball Bearings

NTN Angular Contact Ball BearingsNTN Single Row Angular Contact Ball Bearings

Single row angular contact ball bearings feature raceways with high and low shoulders. These opposing raceways are designed to carry thrust load in one direction.

NTN Double Row Angular Contact Ball Bearings

Double row angular contact ball bearings have an inner and outer ring with a double raceway. The two rows are so related that the contact angle is similar to a pair of back-to-back single row bearings.

NTN Insulated Ball Bearings

NTN Insulated Ball Bearings offer two options to prevent electrical pitting damage. Double row angular contact ball bearings have an inner and outer ring with a double raceway. The two rows are so related that the contact angle is similar to a pair of back-to-back single row bearings.

NTN Coated Insulated Ball Bearings

NTN Insulated Ball BearingsNTN’s MEGAOHM™ Series of insulated bearings has been specifically designed to counteract electrical pitting. These bearings are available in both ceramic and resin versions that are suited to a variety of applications. Coating the outer ring of the bearing provides a barrier (capable of resisting at least 100 M) at 500 VDC) against any stray currents that would pass through the bearing.

NTN Ceramic Hybrid Insulated Ball Bearings

For especially problematic applications, NTN offers ceramic hybrid bearings. Using conventional steel inner and outer rings, silicon nitride rolling elements provide excellent electrical insulation while reducing rotating mass and improving heat dissipation.

NTN Speciality Ball Bearings

NTN Specialty Ball BearingsDouble-row, self-aligning bearings from NTN utilize an inner ring with a single spherical raceway. In this configuration, the inner and outer rings can be misaligned relative to each other. The resulting effect is a comparatively large single angle that imposes moment loads upon the balls. The boundary dimensions of self-aligning bearings can be the same as standard ball bearings.
