400752305 Double Row Cylindrical Roller Eccentric Bearing

Eccentric bearing: It is a bearing whose inner hole center and outer circle center are not on the same center, which is a very useful bearing type. It mainly includes the outer ring, the inner ring, the roller, the roller basket, the eccentric bearing is simple in structure and easy to use, and the eccentric function can be realized without the eccentric shaft, which reduces the manufacturing cost of the eccentric mechanism.

Technical parameter:

Features:

The characteristics of eccentric bearing: the inner hole of the inner ring is an eccentric hole, and there is a longitudinal keyway on the inner wall of the eccentric hole.

Categories:

One is double-layer double-row tapered roller eccentric bearing; The cylindrical roller relates to a single-layer raceway cylindrical roller bearing with small clearance or negative clearance, which is mainly installed on both sides of the plate cylinder and the impression cylinder of the printing machine;

The other is a double-layer raceway with internal and external eccentric negative clearance cylindrical roller bearing unit, which is installed on both sides of the rubber drum of the printing press. Compared with conventional rolling bearings, hollow cylindrical roller bearings have strong vibration absorption ability, long precision life and overload protection functions because of their special structure.
