Needle Bearing Series


Catalog excerpts

Needle Bearing Series - 1

The Needle Roller Bearing Series has been produced at a quality level in conformance with ISO-14001 and ISO-9001 using a production system that reduces negative impact on the global environment. This catalog adopts the SI system (system of international units) in conformance with ISO (International Organization for Standardization) Standard 1000. In the table of dimensions, standard products are referred to using identification numbers marked with . The products are reputed for high quality, reasonable price and quick delivery. The identification numbers marked with refer to our semi-standard products. The specifications and dimensions of products in this catalogue are subject to change without prior notice. The basic dynamic load rating values are based on the equation in JIS B 1518-1992 which takes into consideration the fact that improvements in the quality of bearing materials and manufacturing technologies have extended bearing lives. In addition, the basic static load rating values have been revised according to ISO 76-1987. The bearing accuracy are based on JIS B 1514-2000. 1

Needle Bearing Series - 3

A2 Nippon Thompson Co., Ltd. is a bearing manufacturer that launched the technical development of needle roller bearings for the first time in Japan and is proud of the high quality level and abundant varieties of its products. Needle roller bearings are bearings for rotary motion that incorporate needleshaped thin rollers instead of ordinary bearing balls or rollers. Compared with other rolling bearings, they are small-sized and lightweight but have a large load capacity. They are widely used with high reliability in the fields of automobiles, industrial machinery, OA equipment, etc. as...

.. Machined Type Needle Roller Bearings have an outer ring made by machining, heat treatment, and grinding. The outer ring has stable high rigidity and can be easily used even for light alloy housings. These bearings are available in various types and optimally selectable for different conditions such as heavy loads, high-speed rotation and low-speed rotation. They are most suitable for general-purpose applications. Radial Bearing Page D1 In Needle Roller Bearings with Separable Cage, the inner ring, outer ring and Needle Roller Cage are combined, and they can be separated easily. This type...

.. Cam Followers Cam Followers are bearings with a stud incorporating needle rollers in a thick walled outer ring. They are designed for outer ring rotation, and the outer rings run directly on mating track surfaces. Various types of Cam Followers are available. They are widely used as follower bearings for cam mechanisms and for linear motions. Follower Bearing Page Roller Followers Roller Followers are bearings in which needle rollers are incorporated in a thick walled outer ring. These bearings are designed for outer ring rotation, and the outer rings run directly on mating track...

.. Seals for Needle Roller Bearings Seals for Needle Roller Bearings have a low sectional height and consist of a sheet metal ring and special synthetic rubber. As these seals are manufactured to the same sectional height as Needle Roller Bearings, grease leakage and the penetration of foreign particles can be effectively prevented by fitting them directly to the sides of combinable bearings. Component Part Page L1 Cir-clips for Needle Roller Bearings Cir-clips for Needle Roller Bearings have been specially designed for needle roller bearings on which, in many cases, generally available...
