Part No. 0321708501

This aftermarket replacement OIL SEAL - ROTARY SHAFT SEALOIL, listed under part number 0321708501, belongs to the Hydraulics & Cooling range for counterbalance and warehouse trucks. A rotary shaft seal rides on a thin hydrodynamic oil film maintained by its garter-sprung lip; the lip geometry holds fluid in while the dust lip excludes grit, and the metal case presses into the housing bore as the static seal. External weeping, slow lift or tilt response, pressure loss or rising oil temperature are the field signatures of wear in this circuit; a pressure test at the rated working pressure confirms whether the component still holds specification. Hydraulic and cooling parts are bench-tested at rated working pressure for leakage and flow before dispatch, and sealing faces are inspected for flatness and surface finish. Suitable for TCM forklift trucks. In service it appears across TCM equipment families such as FB Series (1-3.5t Electric), FG/FD Series (1-3.5t IC) and FD 50-80 Series. unit net weight 0.08 kg Supplied with a minimum order quantity of 1 piece.
