Demy (D&M) Bearings Co. Ltd

Model Number: NA4902 Brand Name: BMT Key Specifications/Special Features: Brief introduction:Same cylindrical rollers are the rolling elements of needle roller bearings. They are designed to reduce friction of a surface which is in rotation. Due to its shape, the needle bearing has a larger surface area that is in contact with the outer surface of the bearingAxial needle bearings are flat and a radial pattern while the radial needle bearing have a cylindrical shape and the rollers run parallel to the axis of the shaftNeedle roller bearings consist of an inner race (shaft), needle cage, needle rollers and a race. The rollers are cylindrical, thin, and long. These bearing are compact because there is less clearance between the diameter of the shaft and that of the bearing, this quality makes them suitable for situations where is limited radial space
