Eccentric Roller Bearing

Definition:
Eccentric bearings are a very commonly used bearing type. It mainly includes an outer ring, an inner ring, a rolling element basket, and rolling elements. The eccentric bearing has a simple structure and is easy to use. It can realize the eccentric function without an eccentric shaft, which greatly simplifies the eccentric mechanism and saves labor in the machining of the eccentric mechanism. It saves time, is easy to assemble, and reduces the manufacturing cost of the eccentric mechanism.

Characteristics of eccentric bearings:
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. One is a double-layer double row tapered roller eccentric bearing; the other is a single-layer raceway small clearance or negative clearance cylindrical roller bearing, which is mainly installed on both sides of the plate cylinder and impression cylinder of the printing press; the other is It is a double-layer raceway cylindrical roller bearing unit with internal and external eccentric negative clearance, installed on both sides of the rubber cylinder of the printing press. Due to its special structure, hollow cylindrical roller bearings have stronger vibration absorption capabilities, longer precision life and overload protection functions than conventional rolling bearings.

Applications of eccentric bearings:
Reducer, petrochemical, textile, metallurgy, mining, steel mills and other light and heavy machinery.

 

Common Materials for Eccentric Roller Bearings

Bearings Made of Carbon Alloy Steel
Carbon steel materials are used to produce various components of bearings and have two basic types, Medium versus Low Carbon Alloy Steel.

 

Medium Carbon Alloy Steel Bearings
Bearings made from medium or low carbon alloy steel material are typically called "semi-precision" or "commercial grade" bearings. The inner and outer rings are surface hardened in a heat-treating process call case hardening or carburizing. Bearings made from these materials cannot carry high loads or operate at high speeds and they do not have corrosion resistance. The bearings made from these materials are usually low cost.

 

Low Carbon Alloy Steel Bearings
Low carbon steel is used in the production of bearing cages, metal shields and metal washers around which rubber is molded for seals. The material needs to be protected from corrosion with a coating of oil/grease (cages) or by plating (shields). Additional information on Retainers and Closures can be found in the respective technical bulletins.

 

Maintenance Tips for Eccentric Roller Bearing

Lubricate eccentric bearings regularly to reduce friction and wear; clean the production environment of bearings and other components regularly to prevent dust and debris contamination; and check bearings regularly for signs of misalignment.

 

During the inspection, look for signs of wear, such as abnormal noise, increased vibration, or overheating. These problems can indicate insufficient lubrication, misalignment, or internal damage, and should be replaced promptly.

 

Monitor operating data regularly, such as temperature and noise levels. Also, ensure that bearing seals are intact and operating properly to prevent contamination.
