Description

Technical Field

[0002] Extra-large cylindrical roller bearings are a type of bearing that is widely used in the industrial field. They have the characteristics of high radial load capacity, low friction coefficient, and adaptability to high-speed rotation. These bearings are mainly composed of inner rings, outer rings, rollers and cages. The rollers are cylindrical, which enables them to withstand large radial loads. The inner diameter of extra-large cylindrical roller bearings is generally 40mm, the outer diameter is 80mm, and the width is 18mm, but some roller bearings have an inner diameter of more than several hundred millimeters. For example, the inner diameter of some extra-large bearings may start from 200mm and even reach 1000mm or more.
