Roller bearings are the earliest known type of rolling-element-bearing, dating back to at least 40 BC. Common roller bearings use cylinders of slightly greater length than diameter. Roller bearings typically have higher radial load capacity than ball bearings, but a lower capacity and higher friction under axial loads.
Needle roller bearings are an economical alternative for applications requiring minimal space to carry a given load at a desired speed. They can be an ideal choice because of their ability to handle a given level of speed and load capacity, yet have the smallest cross section of all roller bearing types.
NK55/25-XL Needle roller bearings light series: ... all relevant mounting dimensions should be checked using the information in the dimension drawing. the suitability, performance capability and the expected life of the product should be checked using appropriate methods.
Most rolling-element bearings are either ball or roller bearings. The roller bearing family consists basically of cylindrical, tapered, spherical, and needle bearings. Needle roller bearings are ...
Needle Roller Bearings are bearings for rotary motion that use needle-shaped thin rollers as rolling elements. Compared to ball bearings, they have low sectional height and large load capacity. As a machine part, they help save space by making the whole machine compact.
four-row cylindrical roller bearings are used in roll neck applications. Timken offers both single and multi-row cylindrical roller bearing. Custom designs are available upon request for specific applications. • Spherical roller bearings – Spherical roller bearings offer high radial and moderate thrust capacity together with
Needle Roller Bearings - General Overview. Download PDF of this information. Nomenclature. The prefix letter or letters in the needle roller bearing designation for Drawn Cup (DC) bearings denote whether the bearings are made to inch or metric nominal dimensions as well as their major construction features. For example, a bearing with metric nominal dimensions is indicated by the code letter ...

Needle roller bearings support high speed, high radial loads in confined spaces. Spherical roller bearings support heavy shock loads where misalignment is a risk, such as wind turbines, pumps, paper processing, and fans. Tapered roller bearing cones and cups support high radial and axial loads and are used for such things as axels and gear boxes.
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.

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
