Universal Joint Couplings: what size range does the table cover?

This page covers 10 series (WX/WXD, WF01/WF02, WF03/WF06, WFC, WFH01/WFH11, WSP, SWC-I, SWC, SWCZ, SWCD) with 98 catalogue sizes: bores from Ø6 to Ø1000 mm, rated torque 5.3–8 000 000 N·m. Finished bores, keyways and clamp variants are machined to your shaft; sizes outside the tables are made to drawing.

Universal Joint Couplings: what is it and when should I use it?

Cross-shaft universal joint couplings transmit torque at large working angles and absorb large angular misalignment — a mature, reliable design. SWC-I light and SWC medium solid-yoke series data below; WX mini, WSP telescopic, SWCZ heavy and SWCD short series in the PDF. Use a universal joint coupling when the shafts meet at a large, possibly changing angle — steering, adjusting drives, conveyor and machine drives with large angular misalignment. Choose the light SWC-I or medium SWC series by torque; telescopic (WSP) and mini (WX) versions cover length changes and small drives.

Universal Joint Couplings: can I order a size that is not in the table, or just one piece?

Yes. Everything on this page is made to drawing, and the table is only the standard-size subset of the catalogue. Minimum order quantity is one piece — we routinely make single replacement parts for OEMs whose original supplier has discontinued the item. Send a DWG, STEP or PDF drawing (or a sample part): you get a formal quotation within 24 hours after the information is complete, and the first article ships within 30 days of drawing approval, with inspection records.

Universal Joint Couplings: what do I need to send to get a quote?

Send: shaft diameters and lengths on both sides (with keyways or clamp preference), rated and peak torque, speed, the misalignment you expect (angular, radial, axial), space available (outside diameter and overall length), operating temperature and whether the drive is servo/positioning or general. A drawing or STEP of the two shaft ends is ideal; a sketch with these values is enough for a first quote.
