NET was founded on the repair of Renold Carter Gear. Since then it has provided industry with the most comprehensive repair centre available.

Back in 1971, Nottingham Electrical Transmissions started repairing Carter Gearboxes for the thriving lace industry in Nottingham. As our experience grew, so did our reputation, and we soon became one of the UK’s largest repairer and supplier.
Sadly the lace industry in Nottingham no longer exists, but thankfully we still do and are the UK’s largest and most experienced company still repairing, supplying and offering service exchange units for the Renold Carter Gearboxes. We now have over 45 years experience, a wealth of knowledge and a team of people waiting to offer you a first class service.

We have sizes F10 to F14, and 3A to 6A on the shelf and ready to be dispatched immediately.

From 0.37kW to 37kW
