thinner rollers allow these bearings to fit in tighter spaces than tapered roller thrust bearings. because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low friction jobs. for use on hardened and ground surfaces.. washers allow you to use the bearing on unhardened and unground surfaces.

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.

skf needle roller thrust bearings are fitted with a form stable cage to reliably retain and guide a large number of needle rollers. in applications where the faces of adjacent machine components can serve as raceways, needle roller thrust bearings take up no more space than a conventional thrust washer.
a needle roller bearing is a type of bearing typically constructed from an inner race, needle rollers, a needle cage that contains and orients the needle rollers, and an outer race. they come in two basic types radial needle bearings that are cylindrical and use rollers arranged in parallel to the shaft axis, and thrust needle bearings that are flat and use a radial needle pattern.
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
thrust bearings can be used without thrust washers when the faces of adjacent machine components can serve as raceways, allowing the machine to be even more compact. these bearings provide a high degree of stiffness and are most suitable where high accuracy is required at high speeds and under fluctuating heavy loads, such as machine tools and
