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 BEARINGSPrelubricated 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.

Regardless of your industry type, NTN offer a diverse series of mounted bearing units to fit your application. Whether for mining, construction, or food processing, NTN has the solution for your industry.NTN's Sentinel Series is a premium line of stainless steel bearings and bearing units featuring food-grade solid lube with covers. The Sentinel line is designed for maintenance-free, washdown-resistant product lines in food and beverage applications. NTN's flagship line is designed specifically to decrease downtime and increase profitability. All Sentinel Series products have 100% stainless steel inserts and ball bearings filled with H1 food-grade solid lube. The Sentinel line requires no maintenance for the life of the bearing- simply install and start saving time and money. Food-grade solid lube is a polymer impregnated with H1 food-safe oil, which helps prevent lubricant washout. Oil is stored in a porous solid material that acts like a sponge and releases the necessary base oil to lubricated the components as it rotates. The entirety of the Sentinel Series line come standard with protective covers (caps) for units that provide additional protection against contaminants and moisture, while adding additional safety for maintenance personnel.

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 with a 15 contact angle.

NTN started production of constant velocity joints (CVJs) in Japan in 1963. In 2007, the number of CVJs produced on a cumulative basis surpassed 400 million units. Following aggressive expansion of production worldwide in the 1990s, we now have a strong base of operations to respond to the global sourcing needs of the automotive industry. These operations are supported by a trilateral development system covering the three key regions of the Americas, Japan and Europe. A production and sales system encompassing these three regions has expanded to include China and other parts of Asia.

Hub bearings are becoming more and more unitized, with the number of parts decreasing from the first-generation to the third (GEN3), and evolving into lightweight, compact products. NTN now mass-produces GEN3 hub bearings on a global scale to deliver diverse generations of hub bearings to automobile manufacturers worldwide.NTN satisfies more than 30% of the demand for North American OE vehicle production from NTNs Elgin, Illinois plant. The Elgin plant is the largest manufacturer of hub assemblies in North America, providing more product to OEMs and the Aftermarket than any other single facility. This gives NTN the benefit in the Aftermarket of supplying highly-engineered replacement parts that meet or exceed OE engineering specifications.
