Timken Bearing Installation

Timken Bearing 

For tapered bore bearings, the inner ring is always installed with an interference fit. Unlike cylindrical bore bearings, the interference of tapered bore bearings is not determined by the selected shaft fit tolerance, Timken Bearing but by the advancing distance of the bearing on the tapered journal, shaft sleeve or withdrawal sleeve.

The radial internal clearance of the bearing decreases with the advance of the bearing on the conical journal. By measuring the reduction value, the degree of interference Timken Bearing and the tightness of the fit can be determined. When installing self-aligning ball bearings, carb ring roller bearings, spherical roller

Timken bearings and high-precision cylindrical roller bearings with conical holes, the reduction value of radial internal clearance or the axial propulsion distance on the conical base shall be determined as the measure of interference. See the relevant product section for the guidance values of clearance reduction and axial propulsion distance.

Small bearing

Small bearings can be pushed to a conical base using nuts. In the case of shaft sleeves, sleeve nuts are used. The small disassembly sleeve can be pushed into the bearing hole with a nut. Timken Bearing The nut can be tightened with hook wrench or pneumatic wrench. Before installation, add a little oil to the surface of journal and sleeve.

Timken Bearing Installation

Large and medium bearings

The installation force required for large Timken bearings is significantly increased and hydraulic nuts and / or oiling methods shall be used. The above two methods can significantly simplify the installation process. The oil filling equipment required to operate the hydraulic nut and use the oil filling method is supplied. For details of these products, see the relevant section in the online catalog “maintenance and lubrication products”.

When the hydraulic nut is used to install the bearing, it must be positioned on the threaded part of the journal or the thread of the sleeve, so that the annular piston is close to the inner ring of the bearing, the nut on the shaft or the retaining ring installed at the shaft end. Press the oil pressure into the hydraulic nut through the oil pump to move the piston axially with the force required for accurate installation.

Use the hydraulic nut to install the spherical roller bearing onto the Using the oil injection method, the oil is injected between Timken bearing and journal under high pressure to form an oil film. This oil film separates the mating surfaces and significantly reduces the friction between the mating surfaces.

This method is generally used when installing the bearing directly on the conical journal, but it is also used to install the bearing on the set sleeve and push sleeve specially prepared for the oil injection method. The oil pump or oiler generates the necessary pressure to inject oil between the mating surfaces through the groove and oil distribution channel on the shaft or sleeve.

When designing the bearing layout, the necessary grooves and channels on the shaft must be considered. The spherical roller bearing is installed on the withdrawal sleeve with oil groove. The withdrawal sleeve is pressed into the bearing hole by injecting oil into the mating surface and tightening the screws in turn.
