*Pinion Coupling – TATA 2518 / 4018
(Serated, HT-95mm, Oil Seal 71mm)**
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 71mm, 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
Ensure secure, slip-free engagement through precision serated teeth
Maintain effective oil sealing, preventing leakage at the pinion end
Reduce vibration and driveline shock, improving differential durability
This coupling is ideal for medium-to-heavy-duty commercial vehicle operations, including cargo, tipper, and long-haul applications.
