Slurry Pump Bearing Assembly Lubrication

2019-02-18

It is advisable to preheat the bearing inner ring or cones (never exceed 1200C). Bearing inner ring must stick close to the shaft shoulder or grease retainer. The inner ring, outer ring and shaft spacer of double rows taper roller bearings are not allowed to be exchanged with the corresponding parts of the same kind of bearings.

For type A B C D E bearing assemblies, the single row taper roller bearings are adopted. During assembly, axial gap in the end cover should be adjusted by means of shims. The value of axial gap should be corresponding to the following table.

0.1-0.2

0.15-0.25

0.18-0.28

0.4-0.6

0.5-0.6

For type R S ST T TU U bearing assemblies, double rows taper roller bearings are fitted in the pump end. It is not necessary to adjust the axial gap because the bearings themselves have already ensured this gap. When assemble the bearings, add considerable grease lubrication. Labyrinth and piston rings are installed in the end cover. When install the piston ring, note that it should be diametrically opposite.

It is recommended that lubricating grease used in roller bearings should be No. 2 or No. 3. The recommended initial quantity of grease to be used for each bearing is as following:
