Industrial Gearboxes & Power Transmission
Gear Units, Couplings, Fluid Couplings
We supply industrial gear units from 130 Nm to 1,400,000 Nm — helical, bevel-helical and planetary designs, together with the couplings, fluid couplings and spare parts that keep them running.
Tell us the torque, ratio, shaft arrangement and duty, and we will select the gear unit and the coupling and quote the complete drive package.

Answers before you ask
Frequently asked questions
Can you supply a replacement for a gearbox that is no longer in production?
Yes. Send us the nameplate photo and shaft dimensions and we will identify the unit, then quote the original part — or the current-generation successor where the original has been superseded.
Do you supply gearbox spare parts separately?
Yes. We supply genuine gear sets, bearings, seals and shafts, and we can also arrange overhaul and retrofit of your existing unit.
Which coupling should I use — N-EUPEX, RUPEX, ARPEX or ELPEX?
It depends on torque, misalignment and damping requirements. Give us the torque, shaft sizes and motor / driven machine data and we will specify the right one.
Do you only supply the eight brands shown on your homepage?
No. We source and supply spare units and parts for most international and Chinese industrial brands, not only the eight brands shown on this site.
I do not know the exact model number. Can you still quote?
Yes. Send us a photo of the nameplate and we will identify the exact unit before preparing the quotation for the original part.
Do you supply genuine original manufacturer parts?
Yes. We supply genuine original manufacturer parts. Send us a photo of the nameplate and we can identify the exact unit before quoting, so you do not need to look up a model number.
Do you provide installation guidance, commissioning and after-sales support?
Yes. We provide installation guidance, commissioning support and after-sales support, remotely or on site depending on your project.
What is the delivery time?
Lead time depends on the product and configuration. We confirm the delivery schedule together with the quotation, so you have a firm date before you order.
Which export documents and certificates can you provide?
We can provide applicable CE and ISO documentation, certificates of origin, packing lists and test reports according to the requirements of your destination country.
What payment terms and incoterms do you work with?
We accept T/T and L/C payment, and quote FOB, CIF or EXW terms to suit your project.
Send us your duty data and we will select it for you
A nameplate photo is enough to start. We identify the unit, confirm the specification and quote the original part.
