Heavy-Duty Actuators operate reliably in rugged environments.

October 31, 2014

Designed for use in rugged exterior environments where remote latch actuation is critical, AC-10 and AC-15 are available in both locking and non-locking versions. Flush-mount AC-10 provides direct, single, or multipoint actuation of latch when used with cables, while AC-15 provides direct actuation and features SMT design to minimize protrusion. Both products are constructed of corrosion-resistant materials and designed for reliability in heavy-duty applications. Read More

High-Speed Drives target vertical lathes.

October 24, 2014

Using planetary reducers, high-speed versions of DRP, KRP, and KRPX Drives simplify design of mechanical transmission systems of both large rotary tables used on vertical lathes over 2,000 m and smaller tables used on milling machines. When meshed with drive gear, reducers on TwinDrive and DualDrive solutions cancel 100% of backlash. Reducers have been hardened to allow continuous operating cycles and can achieve rotational speeds up to 28 rpm-1. Read More
