How to Assemble Tapered Roller Bearings

A tapered roller bearing is a conical tapered ring. It can be made of carbon chromium steel or other types of steel. Tapered roller bearings are commonly used in car wheel bearings, as the conical, tapered design of the bearing allows it to handle vertical and horizontal forces. Installing a taper roller bearing requires knowledge of the wheel mechanisms in vehicles and motorcycles. A worn tapered roller bearing can affect the rotation of the wheel after time and must be replaced.

  1. 1

    Dab the roller bearing in grease. Make sure the grease is applied inside and outside the bearing diameter.

  2. 2

    Insert the tapered bearing on the drive hub shaft on top of the outer race bearing, which is an untapered metal ring that goes underneath the roller bearing. The drive hub is the circular assembly that is located in the middle of the wheel. It houses the tapered bearing and outer race bearing.

  3. 3

    Balance the hub driveshaft on a set of parallel support blocks. Use a hydraulic press frame to firmly install the tapered roller bearing into the hub driveshaft seat. Do this by pressing on the hydraulic press frame.

  4. 4

    Place a bearing spacer inside the tapered bearing to ensure the bearing is installed properly. Use a socket wrench to further tighten the bearing. The socket wrench will seal the bearing in place. Apply a non-metallic seal to the bearing to meld the bearing in place. Apply the seal in the drive hub with the sealing lip facing downwards. Tap the seal with a plastic hammer until it is firmly in the seat.
