The Kerk BFW Series general purpose “free-wheeling” nut is for applications not requiring anti-backlash and wear compensation. It provides effective power transmission at minimum cost, and features long life, self-lubricating polyacetal Acme lead screw nuts. Kerkite Composite Polymers are also available as standard options. The secure mounting and convenience of a circular flange is standard on the BFW nuts with triangular flange and thread mounting as an option. Many custom configurations are available. Acme lead screws are 303 stainless steel with extended life, custom Kerkote TFE coating optional. Assemblies can be supplied cut-to-length or with ends machined to customer requirements.
