Drawn cup single row needle roller bearing
Product Description
Needle roller bearing is a special type of roller bearing which uses long,thin cylindrical rollers resembing 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. Like all bearings, they are used to reduce the friction of a rotating surface.
Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding strcture.
Application
Needle roller bearings are widely used in cars, compressors, construction,electric motors,
food industry, home appliances etc. As a rolling element, it turns the world.
Feature
1.Cam follower with needle rollers supports high static and dynamic loads in cam- and track-type applications
2.Stud-type design with a screwdriver slot for through-hole or threaded mounting
Full complement of rollers for higher radial load capacity than caged rollers
3.Nylon lip seals help retain lubricant and prevent contamination
4.Black oxide- treated bearing steel for durability and corrosion resistance

Brief introduction
Needle bearing is a roller bearing with a cylindrical roller, which is thin and long relative to its diameter.This roller is called a needle roller.Although has a small cross-section, bearing still has high load capacity, needle bearing with fine and long roller (roller diameter D 5 mm or less, acuity 2.5 L/D, L) for the roller length, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting structure.
