NTN-SNR
Here at TFL-Bearing, we offer the full range of NTN-SNR products including ball, self-aligning, angular contact, cylindrical, needle, and spherical bearings at highly competitive prices which are available for same or next day delivery
NTN was founded in 1918 when investor Noboru Niwa, his sales company Tomoe Trading Co. and engineer Jiro Nishizono jointly designed and manufactured the first NTN ball bearing.
By 1939, NTN had built the Kuwana Factory, which would later become its global manufacturing center. In 1954, NTN became the first Japanese industrial manufacturer to receive the prestigious Deming Award for Statistical Quality Control. As more factories were established and NTN sales expanded to Europe, NTN continued to grow in the 1950s and 1960s.
The company now has the ability to produce ball bearings, spherical bearings, tapered bearings, cylindrical bearings, needle roller bearings, and automobile constant velocity universal joints. By the mid-1980s, NTN acquired the Bower™ brand from Federal-Mogul, which expanded the company’s tapered and cylindrical roller bearing catalog. Ten years later, NTN acquired BCA™ from Federal-Mogul again to complete its product line of automotive clutch release bearings and special agricultural bearing components.
The success of Qixin’s North American factory continues into the new millennium. A two-year phased investment in French bearing manufacturer SNR was completed in 2008, and NTN acquired a controlling stake in the company. As the fifth-largest bearing manufacturer in Europe, SNR’s involvement in the aerospace industry and its excellent spherical roller bearing products are a key factor in NTN’s continued growth.

NTN-SNR BALL BEARINGS
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. Our ball bearings are available to you off-the-shelf, in sizes ranging from 10 mm to 320 mm outside diameters. And with a virtually limitless variety of configurations of seals, shields, lubricants, internal clearances, and cage designs, there’s no reason to go anywhere else for your ball-bearing needs.
Deep Groove Ball Bearings
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.
Angular Contact Ball Bearings
SINGLE ROW ANGULAR CONTACT
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 can preload the bearings at the factory so that the correct load will develop once the bearing is put into service. The bearings in this series are assembled with a specific internal clearance so that they will have a specified contact angle under load. The standard contact angle used by NTN is 30° but, in many cases, a 40° contact angle can also be specified. We also offer special high-speed bearings with phenolic resin cages and a 15° contact angle.
DOUBLE ROW ANGULAR CONTACT
Double row angular contact ball bearings have an inner and outer ring with a double raceway. The two rows are oriented so the contact angle is similar to a pair of back-to-back single row bearings. NTN’s 5200 and 5300 series offer a one-piece inner ring double row raceway that can carry thrust loads in either direction. The 3200 and 3300 series have filling slots, so it is necessary to mount them with the thrust load acting against the un-notched face of the rings.
Insulated Ball Bearings
Electrical pitting often occurs in bearings used in electrical equipment, such as motors and power generators, as a result of current leakage. An electrical current present near a bearing can flow through the bearing, causing the current to arc between the rolling elements and the rolling surface. The arc created will elevate the temperature of the steel at the arc point and change the material structure of the steel, ultimately leading to bearing failure. This electrical pitting can be prevented with coated bearings or ceramic hybrid bearings.
CERAMIC HYBRID 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.
The unique properties of ceramic rolling elements can also extend service life and extend grease intervals.
Ceramic hybrid bearings are gaining popularity in the wind energy industry, where service access is difficult and conditions especially harsh.
Speciality Ball Bearings
Double-row, self-aligning bearings 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 boundary dimensions of self-aligning bearings can be the same as standard ball bearings.
ULTAGE® SPHERICAL ROLLER BEARINGS
The first spherical roller bearings with metallic shields are proposed in the KIZEI® bearing range. This innovative solution created by NTN-SNR is easy to use and offers production output and equipment reliability optimization while reducing maintenance costs.
Advantages offered by KIZEI®
