Product Introduction

The 3050688000 Cross Joint is a critical drivetrain component used in the propeller shaft assemblies of KAMAZ, URAL, and MAZ heavy-duty trucks.

Installed between the driveshaft yokes, the universal joint transfers engine torque while allowing the propeller shaft to operate smoothly at varying working angles caused by suspension movement and axle articulation.

The universal joint works together with:

• Propeller shaft
• Slip yoke
• Driveshaft flange
• Transmission output flange
• Differential input flange
• Center support bearing (where applicable)

Its primary functions include:

• Transmitting engine torque efficiently
• Compensating for driveline angular movement
• Reducing drivetrain vibration
• Maintaining smooth power delivery
• Improving driveline reliability

During heavy-duty transportation, mining, construction, and off-road operations, the cross joint is subjected to high torque, shock loads, and continuous vibration. Worn or damaged universal joints may cause:

• Driveshaft vibration
• Knocking or clicking noises
• Needle bearing failure
• Grease leakage
• Premature driveshaft wear
• Reduced drivetrain reliability

The 3050688000 cross joint is manufactured from premium 20CrMnTi alloy steel with precision forging, carburizing, quenching, and grinding. Hardened trunnions and high-quality needle bearings ensure excellent wear resistance, smooth rotation, and long operating life.

Designed according to OEM specifications, this universal joint is widely used for KAMAZ, URAL, and MAZ trucks in fleet maintenance, propeller shaft repair, drivetrain rebuilding, mining vehicles, military vehicles, and heavy commercial transportation. OEM references list this joint with a 38 mm bearing cap diameter and 104 mm overall width, making it suitable for numerous heavy-duty driveline applications.

Each cross joint undergoes strict quality inspections including:

• Material composition analysis
• Heat treatment hardness testing
• Bearing clearance inspection
• Precision dimensional measurement
• Dynamic balance verification
• Fatigue testing
• Installation fitment verification

to ensure OEM-level reliability and durability.
