Originally developed by Carter Gears of Bradford and part of the Renold Group since the 1960s, the Carter Hydrostatic Variable Speed unit remains a proven solution for precise, load-independent speed control on heavy industrial drives. It offers an infinitely variable speed range of 27:1 and a power capacity of up to 30kW, in a totally enclosed casing suited to hostile operating environments.

Renold Gears offers a complete repair service for existing Carter units, or can supply a fully refurbished unit from stock. A Service Exchange programme is also available, providing a discounted, fully refurbished replacement in exchange for your old unit.
