TIMKEN MDV21 Tapered Roller Bearings Instructions

Packing a Tapered Roller Bearing With Grease

Proper lubrication greatly increases the life of bearings, especially in adverse conditions

The following are the endorsed instructions for tapered roller bearing lubrication

By Hand

Thoroughly clean your hands or wear a new pair of latex gloves.
Place a golf-ball sized amount of grease into your palm.
Using your opposite hand, push the large end of the bearing cone assembly into the grease, forcing grease between the rollers, cage and cone.
While pushing grease into the large end, rotate the entire cone assembly until the grease is forced out evenly around the entire small end.
Smear excess grease on the outside of the bearing cone assembly.

Using a Mechanical Grease Packer

Thoroughly clean your hands or wear a new pair of latex gloves.
Place the bearing cone assembly, small end down, into the grease packer funnel.
Plug the bore of the large end of the bearing cone assembly with the conical retainer.
Firmly press down on the conical retainer. This forces the grease between the rollers, cage and cone.
Smear excess grease on the outside of the bearing cone assembly.

NOTE: You should allow enough space in the housing for heat dissipation so excess grease throws clear from the bearing. Contain the grease around the bearing. The housing should normally be 1/3 to 1/2 full of grease during bearing assembly. Too much grease in the housing may cause high temperatures and excess churning of the grease.
