SWP-B Short Telescopic Universal Joint Coupling – 16-1250 kN·m, ≤10° Angle, Split Bearing Housing

Factory Direct | JB/T3241-1991 Standard | Short Telescopic Design | Split Bearing Housing | 16-1250 kN·m Torque | ≤10° Axis Angle | 160-640 mm Rotating Diameter | High Transmission Efficiency | Maintenance-Friendly | OEM Customizable

The Apexcoupling SWP-B series is a high-performance short telescopic universal joint coupling (cardan shaft) engineered for heavy-duty industrial applications where axial space is limited but the need for angular misalignment compensation and axial displacement remains critical. Featuring a split bearing housing (剖分式轴承座) design that allows for easy bearing replacement without disassembling connected equipment, the SWP-B delivers exceptional reliability and reduced downtime. With a compact short-body design, it achieves the same torque ratings as the SWP-A in a shorter overall length. Manufactured from high-grade steel and bronze, the SWP-B series is the ideal solution for mining conveyors, crusher drives, metallurgical equipment, shipbuilding, petroleum machinery, and other heavy industrial applications.

✅ Short telescopic design – saves space in compact drivetrains. Split bearing housing – easy bearing replacement without disassembling shafts. 16-1250 kN·m torque – handles heavy loads. ≤10° axis angle – accommodates significant misalignment. High transmission efficiency – up to 98.6%. Smooth operation – minimal vibration. JB/T3241-1991 standard – quality assured.

Product Structure

1. Two Flanged Yokes – Precision-forged and machined from high-grade alloy steel.

2. Cross Shaft (Spider) – Precision-ground cross-spider transmits torque through angular offsets.

3. Split Bearing Housing – The signature feature of the SWP-B series; the two-part housing allows the spider to be replaced with connected shafts left in place.

4. Telescopic Spline Shaft – Provides axial length adjustment with standard stroke S (50-230 mm).

5. High-Strength Bolts – Connect the coupling to other mechanical parts.

💡 How it works: The SWP-B short telescopic universal joint coupling operates on the Hooke’s (universal) joint principle: a pair of flanged yokes joined by a precision-ground cross-spider carries high torque through shaft angular offsets of ≤10°. The split bearing housing is the defining feature – the two-part housing splits radially, so the spider can be changed with the connected shafts left in place. Where mining and mineral processing layouts leave little room to work, that means faster repairs and less time spent in confined spaces. The short telescopic design provides axial adjustment while maintaining a compact overall length.
