Product Structure & Components
Integral Forged Fork Head – One-piece construction without bolt connections – eliminates bolt loosening and breakage, the most common failure point in traditional universal joints.
Cross Shaft Assembly (Spider) – Precision cross shaft with needle roller bearings and grease fittings for smooth rotation and extended service life.
Telescopic Welded Shaft – Standard telescopic design with 40mm stroke compensates for axial displacement.
Flange Connection – 52mm outer diameter flange with 4 holes evenly distributed at 6mm diameter for secure mounting.
Alloy Steel Construction – 42CrMo or 20Cr with quenching process – high strength and durability.
💡 How it works: The SWC65BH cardan shaft uses an integral fork head design that eliminates the weak link of bolt compression bearing seats, completely avoiding common malignant damage caused by bolt loosening or breaking. The service life is 30-50% longer than other types. Torque is transmitted through the cross shaft, while the telescopic shaft accommodates axial displacement. The flange connection provides secure mounting to driven equipment.
SWC65BH vs Other SWC Types – Quick Comparison
| Type | Description | Best For |
|---|---|---|
| BH | Standard Telescopic Welding | General industrial, most common type |
| BF | Standard Telescopic Flange | Quick assembly/disassembly, regular maintenance |
| DH | Short Telescopic Welding | Space-constrained installations |
| CH | Long Telescopic Welding | Large axial displacement requirements |
| WH | Non-Telescopic Welding | Fixed-length applications |
| WF | Non-Telescopic Flange | Fixed-length with flange connection |
💡 BH (Standard Telescopic Welding) is the most commonly used type in the SWC series, offering the best balance of performance, reliability, and versatility for general industrial applications.

FAQ
Q: What is an SWC65BH cardan shaft?
A: The SWC65BH is a standard telescopic welding type universal joint drive shaft with an integral fork head design. It transmits torque between shafts that are not collinear, with angle compensation up to 25°.
Q: What is the advantage of the integral fork head design?
A: The integral fork head eliminates bolt connections, which are a common failure point in traditional universal joints. This significantly improves structural strength, reliability, and service life by 30-50%.
Q: What is the maximum operating angle?
A: The SWC65BH offers 15-25° axis angle compensation – significantly larger than the SWP type (~10°).
Q: What is the transmission efficiency?
A: The transmission efficiency reaches 98-99.8% – providing significant energy savings for high-power transmission applications.
Q: What materials are used?
A: The coupling is manufactured from 42CrMo alloy steel or 20Cr with a quenching process for high strength and durability.
Q: What is the torque and speed range?
A: Nominal torque is 0.25 kN·m, with allowable torque range from 1.25 to 1000 N·m. Maximum speed is up to 4000 RPM.
Q: What industries is this coupling suitable for?
A: Rolling mills, mining, conveyors, paper machinery, ship drives, crushers, test benches, pump equipment, construction machinery, and general industrial applications.
Q: Does the coupling require balancing?
A: For high-speed applications (above normal operating speeds), dynamic balancing is recommended. Please specify when ordering.
Q: Can I get a custom coupling?
A: Yes. We offer OEM customization – custom lengths, telescopic strokes, flange interfaces, materials, and finishes.
Q: What is the warranty?
A: 1 Year – quality assured.
