This locking element handles heavy torque loads in wind turbine gearboxes and other rotating equipment where a secure shaft-to-hub connection is critical, and it does it without maintenance headaches of keyways.
For mining conveyors, CNC spindles, or automotive test rigs, the thing fits bore diameters from 24 to 165 mm and delivers up to 930 Nm of clamping force at speeds up to 4000 RPM, with a 15-to-25-degree operating angle that compensates for minor misalignment.
The standard unit uses C45 steel or 304 stainless steel, precision-ground to H6 tolerance, and comes with either black-phosphate or natural finish—personally, I’d go with black-phosphate for outdoor wind farm exposure, but the natural option works fine in clean machine shops.
Flange diameters span 58 to 440 mm, thickness runs 32 to 140 mm depending on torque requirement, and the whole assembly carries CE and ISO certifications with a one-year warranty, so you’re not gambling on fit in a production run.
Minimum order is ten pieces, OEM branding or custom sizing is available, and the MOQ is low enough to test one setup before committing to a bigger buy—just make sure you check the bore tolerance against your shaft before ordering a hundred.
For custom orders like that, lead time is typically 15-20 working days after design approval. OEM specs can shift it a bit, but that’s our standard window.
Yes, we include CE and ISO certs with every shipment. Just let your sales rep know you need them, and we’ll attach the docs.
The 75 mm outer diameter is the standard for this series, but it’s tied to the bore size and flange range. For specific combinations, we can adjust it under OEM terms.
Each piece is individually wrapped in oil paper and anti-rust film, then packed in a sturdy carton with foam inserts. This keeps them safe during transit and storage.
The black-phosphate treatment doesn’t change the torque rating—it’s purely for corrosion resistance. Both finishes deliver the same 145-930 Nm range, depending on size.
