How To Install A Tapered Roller Bearing?

- Jun 17, 2020-

The tapered roller bearing can be adjusted to a torque of 15 - 20 feet per pound with a rotation of 1 / 8 - 1 / 4. Pull back the bearing according to the manufacturer's specifications and turn 1 - 8 / 1 / 4 "to 15 feet/pound per square inch. 


If the assembly of the tapered roller bearing is not carried out with the utmost care, wear and other damage may occur if incorrect tools are used. After mounting the ball bearing roller and sealing the bearing unit, the right procedure, and the right tool will make a comeback - the free bearing assembly. Zero endings and low preload remain on the wheel bearing assembly.

In the long term, wear and tear can also affect other parts of the machine, and sand and fine metal particles can reach the bearing. The bearing can adjust, which can reduce the service life of a tapered roller bearing and cause damage to the bearings. 


The idea of using the bearing as a spacer to control the final assembly setting may be unknown to many service technicians. Note: This mounting type typically assumes a tapered roller bearing with a diameter of 1.5 inches or less. A special compensation matrix is necessary to accommodate this fit, but it is not necessary. 


If there is an axial adjustment mechanism in your spring-loaded system, you can mount a spacer. For more information on the use of tapered roller bearings and their ability to control spacer width, please read this article. 


This measurement and calculation method requires that the user receives the bearing himself in order to determine the actual fit and assembly practice. Please note that the bearings can be supplied in combination with the spacers if the user intends to produce or purchase each one separately, and the combination of bearing components and spacers should be treated in the same way as the fastening. The use of a separate bearing is not necessary if the nominal target settings are to be achieved. This is due to the difficulty of obtaining a target bearing setting for each bearing. 


To prevent damage to the new bearing, press the inner barrel of the bearing against the shaft. Press the outer race so that it can withstand the same pressure as the inner-race bearing (about 1 / 4 inch). Push the outside of the bearings down and press them against each other. 


The conical bearing shells of the outer race should be driven with a special aluminum driver in the same direction as the inner bearing shells. Most bearings have a built-in bearing bore - in the axis, which means that this type of bearing must be pressed and driven. If the bearing is hammered out of alignment, this can cause a rolling ball to cut through the bearing runs and cause premature failure. 

Remove the hub bearing from the axle, put the disc aside, and reassemble the hubs and axle. Remove and mount the inner cone from the cup, wrap the bearing cone with grease, smear grease onto the cup and smear the tip of the grease seal (I used Sil - Glide). Remove hub bearings from the axles, disassemble and disassemble, insert inner cones into the cups, and set aside. 


Turn the nuts to the specified minimum torque and tighten tightly until the cotter pin can be mounted (approx. 1 / 4 to 1 inch). 


A ball bearing is used to help align the full bearing complex of the roller for assembly and to hold the bearing during tool assembly. The assembly tool should, as shown, have a leader or pilot to assist in starting the bearings corresponding to the housing. Arrange your bearings by tamping the ends, bending the shoulders, and pushing the tools down. 


With tapered roller bearings, the roller is angled so that the roller surface converges with the bearing axis. The inner and outer rings of the track taper at the same angle as the inner ring and the outer ring, but not as far apart as a normal roller. 


This enables the bearing to carry high radial and axial loads in multiple directions and is the only bearing type that can handle large quantities of both axial and radial loads simultaneously. A single row of tapered roller bearings can support both radial and axial loads in one direction. Secondly, this installation puts one of the tapered roller bearings in the same position as a normal roller, but in a different direction from the track surface. 


When the bearing is exposed to radial loading, the axial component is generated in one direction, while we have to balance it if it can carry an axial force in the opposite direction. A tapered roller bearing can withstand axial loading in the direction of adjustment and limit the number of radial loads in both directions, but not in both directions.
