Tapered Roller Bearings 31300 Series ID 25 - 150 mm
Features
Tapered Roller Bearings are designed for using in a wide range of applications, including automotive, tractor, rolling mill, mining, metallurgical, plastic machinery,etc. This is a separable type of bearing. The inner ring (cone), along with the cage and rollers, is one assembly unit; the outer ring (cup) is the other assembly unit. This feature allows the bearings to be fitted separately and adjusted so that the optimum clearance or preload for each application is achieved.
Due to the inclined position of the tapered rollers, the contact lines between the rollers and raceways intersect at a common point on the axis of the bearing. The contact surfaces of the raceways and tapered rollers are modified to limit edge stresses. As a result of this modification and the large number of rollers, this bearing has high load-carrying capacity and is designed to carry axial and radial loads simultaneously. Since a single bearing of this type can only carry axial loads in one direction, the bearings are usually mounted in pairs.
DCM can produce high quality TRB as the customer requests.We are happy to produce further construction methods. Please do not hesitate to contact us for special bearing characters.We can also supply OEM service.
