Cross Holder for Tata Mega/HT (CROSS‑4050BP) — Description
Cross Holder (Round Ø165 mm, Height 135 mm) (Example of a similar heavy‑duty universal joint cross holder compatible with large Tata commercial driveline sizes)
A cross holder for the Tata Mega/HT is a drivetrain component used in the propeller shaft / universal joint (U‑joint) assembly of the vehicle. It plays a key role in ensuring smooth torque transmission while allowing the drive shaft to articulate as the vehicle moves over uneven surfaces.
📌 What It Is
A cross holder (also called a U‑joint cross holder flange) is a mounting support bracket or flange that holds the universal joint cross (spider) firmly between the yokes of the propeller shaft or related driveline segments.
The part designation CROSS‑4050BP refers to the specific size and fitment for the Tata Mega/HT’s propeller shaft U‑joint assembly, ensuring compatibility with the correct cross (spider) and yokes used on this vehicle model.
⚙️ Function
Supports the U‑Joint Cross: The cross holder provides a stable housing and alignment for the universal joint cross, helping maintain proper angular relationships between rotating shafts.
Facilitates Torque Transfer: By securely holding the U‑joint cross and yokes in place, it ensures reliable transmission of engine torque from the transmission or intermediate shaft to the rear differential.
Absorbs Movement & Misalignment: Since driveline components experience changes in angle due to suspension travel and vehicle dynamics, the cross holder lets the U‑joint pivot freely while keeping the assembly aligned.
Reduces Vibration & Wear: Proper support of the U‑joint reduces vibration, noise, and premature wear of bearings and adjoining parts.
📍 Where It Fits
Installed at the universal joint location of the propeller shaft — between two yokes where the U‑joint cross is seated.
Works together with the U‑joint cross (spider) and yokes to create a flexible, torque‑transmitting link in the driveline system of the Tata Mega/HT heavy vehicle.
In simple terms, the Cross Holder (CROSS‑4050BP) for Tata Mega/HT is the steel support flange that keeps the universal joint cross properly aligned and supported within the propeller shaft assembly so that power can be transmitted smoothly even as the driveline angles change during operation.
