Parts & Systems We Supply for Heavy Equipment, AG & Construction
Off-highway and agricultural machinery lives in dirt, shock load, and long hours — and downtime in the field or in-season is expensive. Central Surplus supplies the heavy-duty bearings, hydraulics, and power-transmission parts that keep excavators, loaders, tractors, combines, and material-handling equipment working. As a surplus distributor we can supply obsolete and superseded parts for older iron that dealers no longer stock, and we ship fast so you are not waiting on a backorder.
Categories we supply for this sector include:
- Bearings — heavy-duty tapered roller, spherical roller, and mounted bearings for wheels, axles, and implements.
- Hydraulics & Pneumatics and Cylinders for lift, tilt, and steering circuits.
- Power Transmission, Gearboxes & Speed Reducers, and Couplings.
- Chains & Sprockets for drives and conveying equipment.
Brands Trusted in Heavy Equipment & AG
We stock rugged, field-proven brands including Timken, Bower, Torrington, NTN, Koyo, Dodge, Link-Belt, Rexnord, plus Parker and Rexroth for hydraulics. Give us the number stamped on the old part and we will match it.
Applications & Use Cases
Fleets, dealers, and rebuild shops rely on us for wheel and final-drive bearings, hydraulic cylinder and pump spares, driveline couplings, and gear-reducer parts for augers, feeders, and conveyors. Whether you are repairing a skid steer, rebuilding a combine header before harvest, or sourcing a discontinued bearing for a decades-old dozer, we help you get the machine back to work.
