SKF taper roller bearing skf bearing skf bearings

Adjusting the axial clearance For the installation axial clearance of the SKF taper roller bearing skf bearing skf bearings, the adjustment nut on the journal, the adjusting washer and the thread in the bearing seat hole can be used, or the preload spring can be used to adjust. The size of the axial clearance is related to the arrangement of the bearing installation, the distance between the bearings, and the materials of the shaft and the bearing seat, and can be determined according to the working conditions.

For tapered roller bearings with high loads and high speeds, when adjusting the clearance, the impact of temperature rise on the axial clearance must be considered, and the reduction in clearance caused by the temperature rise must be estimated. In other words, the axial clearance Adjust it appropriately.

For SKF taper roller bearing skf bearing skf bearings with low rotation speed and vibration, they should be installed without clearance or installed with preload. Its purpose is to make the rollers and raceways of the tapered roller bearing have good contact, distribute the load evenly, and prevent the rollers and raceways from being damaged by vibration and impact. After adjustment, check the axial clearance with a dial indicator.

Installation of four-row SKF taper roller bearing skf bearing skf bearings (installation of roller bearings):

1. The fit between the inner ring of the four-row tapered roller bearing and the roll neck generally has a gap. During installation, first install the bearing into the bearing box, and then install the bearing box into the journal.

The outer ring of the two- and four-row tapered roller bearings also adopts a dynamic fit with the bearing box hole. First, install the outer ring A into the bearing box. When leaving the factory, the outer ring, inner ring, and inner and outer spacers are all printed with {HotTag} symbols. During installation, they must be loaded into the bearing housing in the order in which the characters and symbols are arranged. They cannot be interchanged arbitrarily to avoid changes in bearing clearance.

3. After all parts are installed into the bearing box, axially close the inner ring to the inner spacer ring and the outer ring to the outer spacer ring.

4. Measure the width of the gap between the outer ring end face and the bearing box cover to determine the thickness of the corresponding sealing gasket.

Multi-sealed bearings are marked with the suffix code XRS.
