Construction Machinery Oil Seal

Heavy-duty seals for excavators, loaders, dozers and road machinery - wheel hub, final drive, swing gearbox and hydraulic pump positions in NBR and FKM.

Construction equipment works under vibration, shock loads and constant grit. A seal that fails early here does not just weep oil - it takes the bearing with it and stops the machine. The seals in this range use stiffer casings and heavier springs than ordinary automotive parts of the same size.

Sizes and materials

Bore sizes commonly run from 40 mm to 210 mm. Nitrile is standard for gear oil and hydraulic fluid duty; FKM is offered for hot hydraulic circuits and brake applications.

Quality control and inspection

Every production lot is checked for lip geometry, spring tension, case concentricity and rubber hardness, then inspected visually for flash, voids and flow lines before packing. Inspection results are recorded against the batch, so any shipment can be traced back to the lot it came from.
