NMRV040 Stainless Steel Gearbox

1. 304 Stainless Steel Construction
The gearbox features a 304 stainless steel housing and output shaft for good corrosion resistance in wet and humid environments. 316 stainless
steel is available for volume orders when higher corrosion resistance is required.
2. Compact Right-Angle Design
The NMRV040 provides 90-degree power transmission in a compact gearbox design, helping save installation space.
3. Wide Reduction Ratio Range
Reduction ratios from 5:1 to 100:1 are available for different output speed requirements.
4. Easy-to-Clean Surface
The stainless steel housing has a smooth surface that is suitable for applications requiring frequent cleaning and good hygiene.
5. Multiple Motor Mounting Options
Different IEC input flange options are available to match various motor configurations.

1. Longer Service in Wet Environments
The stainless steel construction helps the gearbox withstand moisture and frequent exposure to water, reducing concerns about surface corrosion in demanding operating environments.
2. Lower Cleaning Effort
The smooth stainless steel surface can be washed and cleaned more easily, helping simplify routine maintenance in applications with frequent cleaning requirements.
3. Better Suitability for Hygienic Production
The corrosion-resistant and easy-to-clean construction makes the gearbox suitable for equipment used in food processing and other hygiene-sensitive production environments.
