The Detection of roller bearing Radial Clearance

The roller bearing overview

The roller bearing combines the traditional cylindrical roller bearing and spherical roller bearing configurations. Its proprietary outer race and roller profiles plus a cylindrical inner ring combine the key attributes of both bearing types. This unique three-point contact design geometry provides simultaneous misalignment and axial displacement performance, optimizes contact stress distribution, and helps promote roller stability. The result is a more dynamic, more reliable bearing.

The roller bearing consists of an inner ring, outer ring, and roller/retainer assembly. The separable components simplify installation, removal, and inspection. The retainer holds the rollers in position, creating a single assembly that prevents the rollers from being damaged during mounting and dismounting. The inner ring and outer ring can be installed in either direction, helping to avoid common mounting errors. No special tooling is required.

The Detection of roller bearing Radial Clearance

According to the functional characteristics of the roller bearing and the difference in operating conditions, after selecting the appropriate bearing structure type, the bearings need to be checked routinely. These checks include the specifications and machining accuracy of the bearing and assembly parts, the quality of the lubrication, and the parts are worn out or not, etc.

Of course, after checking the bearing, the following operations should be carried out:

The first is to clean the bearings. One point to note is that the roller bearing with sealed equipment can omit the cleaning process, because the cleaning will cause the intrusion of foreign matter inside the bearing and affect the normal use of the bearing;

Second, it is necessary to adhere to the monotony of the bearing. For bearings that need to be cleaned, after cleaning the rust inhibitor on the bearing, it is necessary to dry the bearing, otherwise, it will easily cause the bearing to rust;

The third is to adhere to the lubrication degree of lubrication.

In addition to the inspection work before the bearing equipment, the radial clearance of the bearing should also be tested. Radial clearance mainly includes the original clearance of the roller bearing under natural conditions, the cooperative clearance that causes the original clearance to change after the bearing equipment, and the actual operating clearance formed under the effect of temperature and load. Since the size of the radial clearance directly affects the operating temperature, oscillation, and service life of the roller bearing, the detection of the radial clearance of the bearing is particularly important.

The roller bearing radial clearance measure

Regarding different bearings, how to measure the roller bearing radial clearance?

1. The measurement of radial clearance needs to use special instruments to measure things as much as possible. When there is no special instrument on hand, a feeler gauge and other things can be used for measurement. When using the manual measurement method, this method has higher requirements on the measurer and is a method prone to error, so it is generally not recommended to use it.

2. For double-row and four-row rolling bearings, the clearance requirements for each row are very important, and it is necessary to test them all.

3. During the measurement, make sure that the rollers of the bearing fall into the bottom of the groove.

The roller bearing Applications

The metal industry\'s tough environment places extreme demand on equipment. That makes maintaining operations and reducing downtime essential in continuous casters where performance and reliability are critical.  The roller bearing innovative design redefines the preferred choice of bearings for the float position in strand roll support segments.
