A high-quality needle roller bearing, designed for seating the planetary gears (satellites) in the planetary hub of the drive axle. It is a key component of the final drive, responsible for the proper and smooth operation of the satellite gears, which reduce the rotational speed and multiply the torque at the wheels. Precision manufacturing and the use of high-grade steel guarantee quiet operation and maximum service life, even under extreme loads.
By choosing GX-OEM parts, you are choosing the uncompromising quality of the original assembly. Our products are made with the highest precision, guaranteeing a perfect fit and parameters identical to the original. This is the best investment in the long and trouble-free operation of your machine.

The list above is for reference. Before purchasing, we recommend verifying the part number in the parts catalogue for your machine.
Repairing a planetary hub is a complex operation requiring specialist knowledge and tools. Always follow the manufacturer's service manual and ensure the machine is secured against rolling.
The satellite bearing is one of the most heavily loaded components in the final drive. Its failure leads to the jamming or improper operation of the gear, which manifests as loud operation, and in extreme cases can lead to the destruction of the entire planetary gear set.
A worn bearing is a direct path to destroying the entire final drive.
The cost of replacing a set of bearings is negligible compared to a planetary gear set overhaul. Don't take the risk – order a proven OEM-quality bearing and restore your drive to factory condition and quiet operation.

This is one of the possible causes. A "whining" or "humming" sound from the wheel hub that intensifies under load often indicates wear in the final drive bearings. Other causes include worn main axle bearings or a low oil level.
2. Can I replace just one damaged satellite bearing?It is not recommended. All bearings in one final drive operate under the same conditions and wear at a similar rate. Replacing only one can lead to uneven load distribution and rapid failure of the others.
3. I found metal filings in my axle oil. What should I do?The presence of metal filings in the oil is a sign of a serious internal failure in the axle or final drive, most often a disintegrating bearing. You should stop work immediately and have it inspected to avoid complete destruction of the gear set.
