WITTENSTEIN releases new NPL-W corrosion-resistant gearbox

WITTENSTEIN alpha, a provider of high-precision servo gearboxes and drive systems, has launched a new corrosion resistant gearbox to support the increasing market demand for components that can withstand processing, overspray and cleaning environments.

Ideal for food processing, bottling and packaging machines, NPL-W features a painted, corrosion resistant housing with no gaps, depressions, undercuts, dead spaces or visible screw heads that could provide a breeding ground for bacteria and microorganisms. The smooth, rounded edges and the lack of horizontal surfaces ensure that any liquids are drained off completely. The sealing concept achieves IP65 (“splash-proof”) protection while the lubricant is NSF® registered food grade certification.

Designed as part of the alpha Value Line family, the NPL-W gearbox features IP65 protection with stainless steel parts and food-grade lubrication. The gearbox is produced exclusively in Bartlett, Illinois, to expedite deliveries in the region where demand has soared for components in packaging and processing applications where safety, reliability and performance is critical.

NPL-W corrosion-resistant gearbox features include:

Two-component paint that resists cleaning agents
Fully painted from output flange through the adapter plate with 2K lacquer
Stainless steel shaft, key, and nut
Nickel Plated Output Flange and Pilot
IP65 seals
Tapered roller bearings
NSF® registered food-grade lubrication

Corrosion resistant couplings and shrink discs made of stainless steel complete the hygienic drive train. These features make the NPL-W corrosion-resistant gearbox suitable for …

High humidity environments
Cleaning process environments
Contact with food, cosmetics, or medical products
Overspray environments with risk of flash rust and oxidation
Other clean-in-place applications

In 2012 WITTENSTEIN designed the first IP69 rated gearbox to achieve EHEDG certification. The HDV series by WITTENSTEIN alpha meets the requirements set new benchmarks in positioning accuracy and power density combined with cleanability and process reliability. This history of excellence continues in the NPL-W line.

Low-backlash planetary gearboxes are used in drives in multiple industries. The requirements profile for these is accordingly very complex: high speeds, low operating noise, high torsional rigidity, low torsional backlash — no two applications are identical. To accommodate the wide range of requirements, WITTENSTEIN offers the most robust portfolio of servo gearboxes on the market. Whether it’s torsional backlash less than 1 arc-min., high speed, continuous operation, high torque, or corrosion resistant designs, WITTENSTEIN’s low-backlash planetary gearboxes offer the full range of motion to meet any precision requirements.
