What do the shaft diameter and radial direction of spherical roller bearings mean?

The shaft of a spherical roller bearing is its management shaft, and its diameter is its diameter. Then the radial direction is the direction of the axis at the management office, and the axis diameter is the diameter direction. The radial direction is generally for cylindrical objects, which is the orientation of the central axis of rotation of the cylinder, that is, the orientation of the axis of the management office. Shaft diameter space quadrilateral radial, that is, the radius or diameter orientation of the thread circle in the cylinder, and the shaft diameter is perpendicular to the radial indoor space design.

How can spherical roller bearings be heated prior to use to facilitate installation?

1. Electric hot plate heating method. Place the spherical roller bearing on a hot plate with a temperature of 100 ° C for a few minutes. This method is the simplest. If it is turned over several times, the bearing can be heated evenly, and the efficiency is also high. Both large and small spherical roller bearings can be used. this method.

2. Electric furnace heating method. The spherical roller bearing is heated in a closed automatic temperature-controlled electric furnace, the heating is uniform, the temperature control is accurate, and the heating is fast, which is suitable for the occasion of heating many bearings in a batch.

3. Induction heating method. The use of induction heaters can quickly, reliably and cleanly heat the spherical roller bearing to the required temperature, which is especially suitable for occasions where the inner ring is tightly fitted. Since only the inner ring is heated, and the outer ring is heated very little, this makes it easier to install on the shaft and into the seat hole.

Why perform engineering overhaul on spherical roller bearings?

In the whole process of industrial equipment maintenance, it is necessary to accurately grasp the direction requirements of industrial equipment spherical roller bearings. Only proper installation can provide guarantee for its operation.

Because the external characteristics of some industrial equipment spherical roller bearings are not very obvious, they can be installed in any direction, so the difficulty of reverse installation often occurs.

Therefore, when installing the spherical roller bearing, the maintenance personnel must grasp and accurately grasp the installation and structural requirements of the spherical roller bearing, and grasp the relevant provisions of the instruction manual in multiple directions, so as to ensure the maintenance work of the spherical roller bearing. high accuracy and efficiency.

SHANDONG CHIK BEARING CO., LTD has been developing spherical roller bearings for several years, and is known as "the national brand leader in the Chinese bearing industry". You can buy spherical roller bearings here with complete confidence.
