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 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.
A needle roller bearing is a bearing that uses small cylindrical rollers. These rollers are used to reduce friction of a rotating surface. Compared with ball bearings, needle roller bearings have a large surface area that is in contact with the bearing raceway journals.
Needle roller bearings - Product description. 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.
Schaeffler's INA brand's needle roller bearings, with substantially improved load ratings, offers higher performance, longer service life, reduced friction and lower bearing temperatures. The result is greater efficiency for your applications and an unbeatable price-to-performance ratio.

Needle rollers can be used to design full complement bearing arrangements for low-speed or oscillating applications. These compact bearing arrangements have a very high load carrying capacity when compared to bearings with a cage and are economical, provided the shaft and housing bore can serve as raceways ( Raceways on shafts and in housings ).
Oct 27, 2023 · Needle roller bearings are meticulously crafted mechanical devices that have been engineered to address two critical challenges: minimizing friction and evenly distributing loads within machinery. Their defining characteristic lies in the utilization of elongated cylindrical rollers as opposed to the more conventional ball bearings.
