Gast 1UP-NRV-11-GR11 Gear Motor

Description

The 1UP-NRV-11-GR11 is a “workhorse” for precision tasks. The 8-vane configuration is a critical technical upgrade over the 4-vane models; it provides smoother rotation, more consistent torque at low speeds, and better “inching” control. Because it is powered entirely by compressed air, it is ATEX and CE certified, making it safe for use around flammable vapors or combustible dust where electric motors would be dangerous.

The motor is designed for face mounting and can operate in any plane (horizontal or vertical), though horizontal or shaft-down is preferred for optimal gearbox lubrication.

Features

15:1 Gear Reduction: Converts high-speed air motor rotation into a stable, high-torque output with a maximum no-load speed of 400 RPM.
8-Vane Performance: Offers superior low-speed stability and more reliable start-ups under load compared to 4-vane versions.
Compact Footprint: Measuring approximately 7-5/16″ in length, it fits into tight machine frames where larger gear motors cannot.
Variable Speed: The output speed can be precisely adjusted from 50 to 400 RPM by regulating air pressure or flow.
Reversible Rotation: A 4-way control valve allows for instant directional changes, ideal for tensioning or indexing tasks.
Stall-Safe: Can be stalled indefinitely under load without damage or risk of overheating, providing natural overload protection.
