Overhaul Services for Gears and Pumps
Bearings Specialist provides complete gearbox overhaul and pump overhaul services for industrial rotating equipment across Thailand. Our workshop and field technicians strip down, inspect, repair, and rebuild gear reducers, gearboxes, and industrial pumps to restore them to full working condition, extending equipment life and avoiding the higher cost of full replacement.
Gearboxes and pumps are among the most expensive rotating equipment to replace, but with the right overhaul process they can often be restored to like-new performance at a fraction of replacement cost. A proper overhaul goes beyond simple repair — it includes full disassembly, precision inspection of every component, bearing and seal replacement, and reassembly to original tolerances. This reduces the risk of repeat failure, extends the service life of your equipment, minimizes unplanned downtime, and gives you a documented record of what was found and repaired for future maintenance planning.
Bearing Clearance Expertise Built In
Because Bearings Specialist works with bearings every day, our overhaul teams don't just replace parts — we set every bearing to the correct manufacturer-specified internal clearance during reassembly. Incorrect bearing clearance is one of the most common causes of early gearbox and pump failure after a repair, and it's often overlooked by general workshops. Getting this right the first time means smoother running, lower vibration, and a longer service life for your rebuilt equipment.
