Micro Series Anti-Backlash Nut for 2mm Diameter Screws

Haydon Kerk has over 35 years of experience in the design of anti-backlash technologies and precision lead screws. Its new Micro Series ZBM nuts utilize a special nut thread system that, when combined with a radial force, provides simple backlash compensation. Initially designed for the optics-focusing market, the ZBM nut performs well in applications in which precise, smooth motion is required and space is at a premium.

The new nut falls within the current dimensional envelope of standard freewheeling nuts, making a transition to an anti-backlash system easier. The design also is optimized for high-quantity production, allowing for best-practice, high-production efficiencies along with rock-solid performance.

Utilizing Kerkite engineered polymers or customer-specified materials (including PEEK), Haydon Kerk can design and manufacture a lead screw nut that delivers smooth, efficient rotary-to-linear motion conversion. In addition, with the use of a Kerkote® TFE coating, Haydon Kerk can effectively reduce the amount of torque required to produce the same amount of force. That, in turn, can lead to a longer assembly life as well as a possible reduction in motor size.
