Overall eccentric bearing, also known as eccentric bearings, is a very useful bearing type. Includes outer, inner ring, ball basket, ball, the whole eccentric bearing structure is simple and easy to use, can be achieved without eccentric shaft eccentric features, to greatly simplify the eccentric body, while making province of eccentric bodies machining work , time-saving, easy assembly, reduces the manufacturing cost of eccentric bodies. Overall eccentric bearing characteristics: inner ring bore hole for the eccentric, eccentric hole on the inside wall in a vertical keyway. The overall classification of eccentric bearings: A double-decker double row tapered roller bearing eccentric; cylindrical roller way for the small roller clearance single negative clearance or cylindrical roller bearings, mainly installed in the printing plate cylinder and impression cylinder on both sides; another way for the double-roller with a negative clearance inside and outside the eccentric cylindrical roller bearing units, installed in the printing rubber roller on both sides. Hollow cylindrical roller bearings because of its special structure, compared to the conventional rolling bearing vibration absorption capability and high accuracy and long life and overload protection. Application of the whole eccentric bearings: speed reducer, petrochemicals. Textile, metallurgy, mining. Steel, etc.. Weight machines.
