Transmission Repairs Company supplies inch and metric Timken bearings to repair shops, distributors and equipment operators worldwide, from single replacements to complete repair sets.
"When we had a gearbox failure on a mining conveyor, we needed Timken spherical roller bearings urgently. They identified the correct Timken reference from our old bearing, shipped same-day, and the gearbox was back up in under a week. That kind of response saves money in downtime."
