The Wheel Bearings 633295 Features:

The wheel bearings is developed on the basis of angular contact bearing and tapered roller bearings combination of the tow sets of bearings. So it has the best features as below:

1. Assembled with good performance, can be omitted clearance adjustment

2. Light weight, compact structure.

3. Powerful load capacity, to advance into the grease sealed bearings, seals and hub omitted from the outside wheel maintenance, etc.

It present it has been widely used in cars, in the truck also has a tendency to gradually expand the application.

Wheel Bearing Maintenance :

1. Remove the hub shaft head decorative cover, dust cover.

2. Remove the tire and tire nut, be careful not to bruise the tire bolt threads. If the disc brakes, the brake should be removed, and then used pliers to remove the lock ring or locking pin. 

3. With a special tool to remove the hub.
4. Scrape bearings, journal and hub cavity old grease, cleaning wheel bearings and journal with a cleaning agent and wipe with a cloth, wipe with a cloth wheels last cavity.
5. Check the wheel bearings and bearing races, found cracks, fatigue spalling and other phenomena loose roller bearings, replace bearings. If you find pitting on the bearing race, it should replace the bearings. 

6. Check the bearing bore and the journal, with the gap should not exceed 0.1Omm measuring journal, should be in the upper and lower parts of the vertical ground (where the largest wear parts) measurements. If used with the gap exceeds the limit, replace the bearings, so back to normal with the gap. Burr is not allowed to play, pitting the journal to narrow the gap.
7. Subject to all parts meet the requirements, apply grease to the bearing after release hub.
8. Apply grease to the bearing cavity attention should grease the bearing until grease to squeeze until the smoke from the other side of the bearing. In the hub and shaft cranial cavity Apply a thin layer of grease to make it play a role in rust. Note that the hub cavity smear of grease do too much, otherwise it will affect the cooling and braking.

9. The hub and outer bearing back onto the journal, hand-axis head adjustment nut and shaft torque wrench required to tighten the adjusting nut. After tightening the nut, turn the wheel a few times to be around to see the bearing installation; on the other hand, by turning the bearing and seat properly fit. At this time bearing tightness appropriate wheels to rotate freely and not feel the axial clearance.

10. Finally, in order to install the locking plate, lock nut, tires, dust cover and decorative cover and other parts.
11. After adjusting wheel bearings, with some mileage (about 1Okm), stop and check for temperature swab touched wheels, if fever, is caused by the bearing adjustment too tight, should be re-adjusted, proper relaxation bearing tightness.
