Bearing Service & Supply, Inc.

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.

Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia forces that facilitate size and weight reductions in machinery. They’re designed to withstand oscillation, perform under severe conditions, and interchange with sliding bearings. Diverse types of needle bearings are available in a wide variety of sizes and tolerances, for a multitude of applications. Needle roller and cage assemblies are offered in single or double row, solid or split cage, metric and inch sizes; as well as in connecting rod bearings for special applications. Single and double row bearings are available with or without ribs, and with or without inner rings. Thrust bearings are offered in single row roller and cage assemblies. Yoke and stud type track rollers are also available. Needle Roller Bearings

Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted. PREMIUM BRANDS, PREMIUM MATERIALS We offer premium cylindrical roller bearings under the NTN and Bower® brand names. Most NTN and all Bower® cylindrical roller bearings feature case-carburized components. Rings and rollers are made from case-hardened alloy steel of “Bearing Quality” to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you’re looking for an American-made, case-carburized inch series cylindrical, or a metric series through-hardened variety, NTN has you covered with a proper fit to your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.

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. 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.

• SeriesSENTINEL™ SERIES

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.

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.
