Product Overview

The SWC Cross Shaft Telescopic Universal Joint Shaft (welded fork type) is a heavy-duty power transmission component designed for industrial machinery requiring angular and axial compensation. Manufactured to JB/T5513-1991 standard, this drive shaft features a welded fork connection and telescopic spline section for length variation during operation. The forged steel construction and precision cross shaft assembly ensure reliable torque transmission under high-load conditions.

Key Features

• Welded Fork Connection – Secure, permanent joint for high-torque applications

• Telescopic Spline Section – Accommodates axial length changes (up to 10 mm compensation)

• Cross Shaft Design – Smooth multi-angle transmission with minimal vibration

Design & Operating Principle

The SWC telescopic universal joint shaft consists of:

• Welded fork yokes (fork ends)

• Cross trunnion (cross shaft) with needle or sliding bearings

• Telescopic spline section for length compensation

• Welded connection to driven/driving equipment

How it works:
The cross trunnion allows the shaft to transmit torque while operating at an angle. The telescopic spline section accommodates length changes during operation, while the welded fork provides a permanent, high-strength connection. Multiple joints can be combined for larger angles or offset shafts.

Key advantages:

• High torque capacity for heavy industrial loads

• Angular and axial compensation for flexible drivetrain layouts

• Welded connection for permanent, secure installation

• Rugged construction for harsh environments

• ISO-certified quality for reliable performance
