🔩 Gearbox Flange – GBS 1150 (Serrated, Coated)

📌 Application

Gearbox Model: GBS 1150 series
Position: Mounted on the gearbox output shaft, connecting to the propeller shaft or intermediate driveline flange.
Use Case: Heavy-duty trucks, buses, and commercial vehicles requiring high-torque transmission.

⚙️ Key Features

Serrated / Splined Surface:
- Ensures positive mechanical engagement with the mating flange or propeller shaft yoke.
- Reduces backlash, prevents slip under high torque loads, and improves driveline stability.
Coating:
- Typically anti-corrosion coating (phosphate, zinc, or paint) to protect against rust and wear.
Height:
- 90 mm, providing correct alignment and spacing in the driveline.
Material:
- Heavy-duty hardened alloy steel, suitable for high torque and shock absorption.
Bolt Pattern & Fitment:
- OEM-specified bolt pattern for secure attachment to gearbox output.

🛠️ Function

Torque Transmission: Connects the gearbox output to the propeller shaft or intermediate shaft flange.
Positive Engagement: Serrated teeth prevent slippage and ensure smooth rotation under heavy loads.
Durability: Coated surface resists corrosion and wear, increasing service life.

🔹 Driveline Placement

Gearbox Output → Gearbox Flange (Serrated, Coated, 90mm) → Propeller Shaft → Differential → Axles → Wheels

The gearbox flange is a critical torque-transfer interface in the driveline. Proper alignment and secure engagement are essential for vibration-free operation.
