needle roller bearings are used to help prevent stress on rollers. designed small in diameter, these bearings can help extend bearing service life. find durable needle bearings that can be used in engine components like rocker arm pivots, pumps, compressors, transmissions and more.
as with most roller bearings, needle roller bearings have two rings with a groove or race machined into each ring and a number of rollers held between the races by a cage. the rollers rotate between the races, allowing one ring to move while the other ring remains stationary, thereby reducing friction and allowing the shaft to rotate freely.
needle roller and cage assemblies are single or double row units comprising cages and needle rollers. as their radial design height only corresponds with the diameter of the needle rollers, needle roller and cage assemblies can be used to realize bearings with a minimal radial design envelope.

needle bearings can take huge loads at high speeds. they feature a great many small diameter cylindrical rollers within each bearing and this ensures a large area remains in contact with the rotating surfaces, which is how they are able to handle heavier loads. full complement needle roller bearings do not need a retainer, whereas the caged
drawn cup needle roller bearings have a drawn outer shell serving as a raceway for the rollers and are installed with a press fit in the housing. they are ideal for many of the following applications transmissions, transfer cases, engines, valve trains, steering and braking systems, axle supports, outboard engines, textile industry, power
bearings direct supplies a large variety of roller bearings and needle roller bearings. roller bearings are any cylindrical or spherical object that aids in the movement of an object greater in size than the bearing itself. a roller bearing is a weight distribution oriented bearing.
nsk drawn cup needle roller bearings (with a cage and full complement of rollers) have a unique outer ring structure. they have the following features the thinnest outer ring among rolling bearings, high load capacity, high maximum permissive load owing to the use of carefully selected special alloy steel plates, a surface hardened cage with high resistance to wear, high limiting speed, and
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.
