Installation method for self-aligning roller bearings

1. Measurement and adjustment of radial clearance

To ensure that the radial clearance reserved for the radial thermal expansion of the inner ring, rollers, and shaft during operation is not too large or too small, and to prevent changes in clearance during later installation, the following measurements should be taken. When the specified installation clearance cannot be achieved, gradually adjust it to the specified installation clearance according to the regular installation method.

The bearings installed using the A heating method require the shaft and bearings to be isothermal before re measuring the installation clearance.

Before installing the lock washer, measure the installation clearance again.

Measure the installation clearance again when replacing the oil pressure nut with a locking nut.

After unloading the oil pressure of the oil pump, measure the installation clearance again.

2. Axial positioning and adjustment of self-aligning roller bearings

(1) Pressing method for inner ring of self-aligning roller bearing

Use locking nuts, end caps, end caps, or hydraulic nuts to directly press the bearing onto the tapered shaft;

Use locking nuts or hydraulic nuts to directly press the bearing onto the B set sleeve;

Use a locking nut or hydraulic nut on the shaft to press and install the C disassembly sleeve to install the bearing.
