FAQ


Q: How can our team check if a rotation problem is caused by the swing gearbox rather than the swing motor?
A: Drain a sample of the gear oil from the reduction box; if you see bright bronze or steel particles, the internal planetary gears are wearing down. Our gearbox uses deeply hardened gears to resist wear, avoiding sudden failures.
 
Q: Are the mounting bolt patterns on this unit a direct match for short-tail crawler series frames?
A: Yes, the mounting base matches the factory frame dimensions perfectly. This precise machining allows your team to bolt the gearbox directly into the tight compartments of short-tail excavators without any structural modifications.
 
Q: For large-volume wholesale orders, what quality control steps does your factory take for these gearboxes?
A: Every single gearbox goes through automated rotational test runs to measure backlash tolerances, torque stability, and seal performance. We send a verified quality certificate with each shipment to guarantee consistent, reliable performance.
 
Q: Can this reduction gearbox work reliably in sub-zero winter temperatures without the gears seizing up?
A: The internal clearances are precision-engineered to stay stable across a wide temperature range. When paired with the right winter-grade gear oil, the planetary gears move smoothly and freely, even on freezing jobsites.
 
Q:  What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
