Universal Cardan Drive Shaft SWC250WH for Crusher

Rotational power begins at the crusher’s motor and enters the SWC250WH through a coupling or flange connected to its input yoke, then travels through the shaft body toward the output yoke attached to the crushing mechanism. The cardan joint, also known as a universal joint, consists of two yokes oriented at right angles to each other with a cross-shaped bearing in between, allowing the shaft to transmit torque at an angle rather than requiring a perfectly straight connection. As the motor rotates, torque passes through the input yoke to the cross-shaped bearing and onward to the output yoke, with the SWC250WH cardan drive shaft flexing and adjusting continuously to accommodate any misalignment that develops between the driving and driven components.

Once torque reaches the output shaft, it drives the crushing mechanism, whether that consists of rotating drums, jaws, or hammers depending on the crusher type, and the material feeding through the machine is processed and reduced in size as a result. Throughout continuous operation, the SWC250WH cardan drive shaft keeps accommodating any variations in distance or alignment between motor and crusher, which is precisely why its flexible, sealed-joint construction is specified across UK quarrying and recycling sites running high-throughput crushing schedules.

Lmin is the minimum collapsed length of the shaft body. D1, D2, and D3 are reference diameters at the yoke and flange connection points. Lm is the spline engagement length, n-d the bolt hole count and diameter, and k, t, b, g are flange and keyway dimensions used for fitting against the customer’s gearbox or motor housing.

The universal joint configuration of the SWC250WH suits a wide family of crusher types, and the cards below set out the specific roles this product plays across UK quarrying, mining, and recycling operations.

Our facility is dedicated to the research, design, and manufacture of cardan drive shafts and related transmission components for metallurgical machinery, papermaking machinery, woodworking machinery, plastics machinery, mining machinery, and textile machinery. Computerised design technology, numerical-control machining equipment, and full-process inspection give every SWC250WH unit leaving the line consistent dimensional accuracy, whether the order is a single replacement shaft or a scheduled batch supply for a UK quarrying or recycling operation.

Length, flange size, and joint configuration on the SWC250WH can all be tailored to match a specific crusher installation, removing the guesswork that comes with fitting a generic catalogue part to a non-standard machine layout. Engineers work directly from customer drawings or sample parts to confirm fit before production, supporting OEM partners and replacement parts buyers across UK manufacturing regions including Yorkshire, the South West, and the Midlands.

Self-inspection runs on every unit before packing, and material certificates are available on request for buyers who need traceability documentation as part of their own quality system. Shipments are prepared with UK import requirements in mind, and a dedicated sales engineer is assigned to each enquiry so that specification questions get a direct, technically informed answer rather than a generic catalogue reply.

Finished SWC250WH cardan drive shaft units pass through a final dimensional check before packing, with each batch matched against the customer’s confirmed drawing or sample reference. This step-by-step verification process is part of why repeat UK buyers return to us for both standard catalogue orders and bespoke crusher projects.

An aggregate quarry near Leeds had been experiencing recurring drive shaft failures on its primary jaw crusher, with the maintenance team tracing the issue to a worn universal joint that was no longer compensating adequately for the misalignment that developed as the crusher frame shifted slightly under sustained heavy feed loads. The site’s operations manager reported that unplanned stoppages were becoming more frequent during peak production periods, directly affecting throughput targets and adding unplanned cost to scheduled maintenance.

After reviewing the crusher’s torque requirement, feed material characteristics, and the degree of misalignment present, our engineering team recommended an SWC250WH cardan drive shaft sized precisely to the existing connection points, replacing the worn unit without requiring any structural modification to the crusher housing. The robust, precision-engineered construction was specifically selected to handle the demanding, continuous-duty conditions typical of primary aggregate crushing.

Since the replacement, the quarry has reported a marked reduction in unplanned stoppages and noticeably more consistent throughput across peak production periods, with the maintenance team noting that vibration levels on the crusher frame have settled considerably compared with the previous shaft. The site has since placed a standing order for spare units to keep on hand for future scheduled maintenance.
