SKF needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.
Needle roller bearings (sometimes called “needle bearings”) use long and narrow cylindrical rollers that sometimes exceed JIS/ISO size ranges. They are categorized as thrust or radial bearings based on which load direction they support.
Needle roller bearings have a long track record as proven machine elements for the design of radially compact bearing arrangements with very high load-carrying capacity. In X-life configuration, they now have an up to 50 % longer service life. To the medias product catalog. Product variants of needle roller bearings.
A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. [1]
Needle rollers are the load-carrying component of the bearing, and are the one common component of all needle roller bearing types. These allow the outer and inner rings to rotate almost friction-free.
SKF needle roller bearings with machined rings are made of carbon chromium bearing steel. SKF supplies these bearings with or without flanges on the outer ring, in a wide range of series and sizes. SKF also supplies them with or without an inner ring.
SKF combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing. They can accommodate both radial and axial loads.
The SKF product range covers all bearing types. Where space is at a premium, SKF needle roller bearings can be the answer. They are available in all the sizes and designs normally offered on the market and have the high and consistent quality which is the hallmark of SKF bearings.
Needle roller bearings. The compact end of the comprehensive SKF range. Bearing arrangements are complex systems. They can only be given an optimum design if a complete bearing range is available to choose from. Where space is at a premium, SKF needle roller bearings can be the answer.
