Introduction

Cylindrical roller bearings are available in a wide range of designs, series, variants and sizes. The main design differences are the number of roller rows and the inner/outer ring flanges as well as cage designs and materials.

The bearings can meet the challenges of applications faced with heavy radial loads and high speeds. Accommodating axial displacement (except for bearings with flanges on both the inner and outer rings), they offer high stiffness, low friction and long service life.

Cylindrical roller bearings are also available in sealed or split designs. In sealed bearings, the rollers are protected from contaminants, water and dust, while providing lubricant retention and contaminant exclusion. This provides lower friction and longer service life. Split bearings are intended primarily for bearing arrangements which are difficult to access, such as crank shafts, where they simplify maintenance and replacements.

Structural and Features

The raceway and rolling body of cylindrical roller bearing have geometric shapes. After the improved design, the bearing capacity is higher. The new structure design of the roller end face and the roller end face not only improves the bearing axial bearing capacity, but also improves the lubrication condition of the roller end face and the contact area of the roller end face and the roller end face, and improves the bearing’s performance.

Features and Benefits

● High load carrying capacity

● High stiffness

● Low friction

● Accommodate axial displacement

Except for bearings with flanges on both the inner and outer rings.

● The open flange design 

Together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capability.

● Long service life

The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.

● Enhanced operational reliability

The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

● Separable and interchangeable

The separable components of XRL cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.

Application

Widely used in large and medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting and transporting machinery.
