The gearbox bearing is a crucial component that supports shafts and gears, ensuring their smooth rotation and minimizing friction. If you hear a loud "whining", humming, or "rumbling" from your machine's gearbox that changes with engine speed, you have difficulty shifting gears, or you find metal shavings in the oil, these are classic symptoms of a failed bearing. Ignoring the problem leads to bearing seizure, which in turn destroys shafts, gears, and the gearbox housing.

The accuracy and quality of materials guarantee long and trouble-free use without the need for frequent replacement.
The bearing is fully adapted to work with original shafts and housings, ensuring a consistent repair.
The ARB brand is a proven and safe alternative that offers quality comparable to original parts at a much better price.
Bearings in a gearbox wear at a similar rate. Replacing only one failed bearing is uneconomical and leads to another failure in a short time.
Use a hydraulic press and appropriate sleeves to install bearings. Hitting a bearing with a hammer will cause immediate damage.
Before installing new bearings, ensure that the housing bores and shaft journals are not worn or oval. This is crucial for the longevity of the repair.
After the repair, fill the gearbox with fresh, dedicated oil, such as HYPTRON, and install a new oil filter, such as one from REDX.
Answer: Whining or humming is a classic symptom of worn bearings. It can also be a symptom of worn gears. The presence of a large amount of silver metal flakes in the oil almost always indicates bearing failure.
Question: Can I replace only one failed bearing in the gearbox?Answer: This is highly not recommended. Disassembling a gearbox is costly and time-consuming. Replacing the complete set of bearings and seals at once is the best and most reliable service practice.
Question: What is the main cause of gearbox bearing failure?Answer: The most common causes are contaminated oil (due to an old or faulty filter), low oil level, or material fatigue after many thousands of operating hours.
