MACHINED TYPE Needle Thrust Bearing MR-12 MR12.2RS MR-12-2RS MR12SS
MACHINED TYPE NEEDLE ROLLER BEARINGS MR-12 MR12.2R
Product Description
The needle roller bearing is a bearing which uses small cylindrical rollers.They are used to reduce friction of a rotating surface. Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance (difference between the diameter of the shaft and the diameter of the bearing) so they are much more compact.
The typical structure consists of a needle cage which orients and contains the needle rollers,the needle rollers thems.elves, and an outer race (sometimes the housing itself).Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft.Thrust needle bearings are flat and use a radial pattern of needles.Full complement bearings have solid inner and outer rings and rib-guided cylindrical rollers.
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
