**Pinion Coupling – TATA 2518 / 4018
(Serated, HT-95mm, Oil Seal 76mm)**
Part Name: Pinion Coupling (Serated Type)
Applicable Vehicles:
TATA 2518
TATA 4018
Category: Driveline / Rear Axle / Differential Component
Description
The Serated Pinion Coupling for TATA 2518 and 4018, with a height of 95mm and oil seal size 76mm, is a heavy-duty driveline component designed to connect the propeller shaft to the differential pinion assembly.
It is engineered to:
Transmit high torque efficiently from the propeller shaft to the pinion gear
Provide secure, slip-free engagement through precision serated teeth
Ensure effective oil sealing, preventing leakage at the pinion end
Reduce vibration and driveline shock, extending differential service life
This coupling is ideal for medium-to-heavy-duty commercial vehicle operations, including cargo, tipper, and long-haul applications.
