Bearings #5141635

With more than ninety years of manufacturing expertise in ball bearings, NTN offers one of the industrys 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, theres no reason to go anywhere else for your ball bearing needs.

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. Theyre 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 MATERIALSWe 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 youre 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.

Spherical roller bearings are dedicated to extremely severe applications and must support high loads, severe misalignment, contaminated environments, shocks, and vibrations. And with the industrys highest load rating and production coming from a factory near you, theres no reason to look anywhere else for spherical roller bearings.NTN-SNR sphericals feature the industrys highest load rating: a full 18% higher than a standard spherical roller bearing. This level of quality means at least a 75% extension of service life. The performance of these sphericals is achieved through the use of very high quality raw materials and optimized rolling element geometry. The unique design also leads to: Reduced friction torque (as much as 30% less), offering lower operating temperature, with lower power and lubricant consumption.Appreciably increased operating speed, allowing an extended scope of applications.High temperature capacity of up to 200C (392F) for metallic cage bearings. Dimensional stability is ensured by a specific heat treatment.A +- 0.5 misalignment capability, without reducing the load capacity, and up to 1 30 in case of low loads.
