UNM AS5070 Thrust Needle Bearing 50x70x1mm 14pc

This listing is for 14 piece/s.A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling 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. 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 structure. Specifications Inner Diameter: 50 mm Outer Diameter: 70 mm Width: 1mm
