The stainless steel worm gearbox is developed for hygienic and highly corrosive working conditions. Adopting stainless steel housing and worm-and-worm-gear transmission structure, it realizes right-angle direction change and speed reduction output. It balances corrosion resistance and steady torque output, widely used in food processing, pharmaceutical, aquaculture, water treatment and other equipment under clean and corrosive environments.
Integrated stainless steel housing
The housing of the stainless steel worm gearbox is integrally machined from 304 stainless steel, featuring a smooth surface without dead corners and no paint coating, and it withstands high-pressure spray cleaning.
90° right-angle worm gearing structure
The input shaft and output shaft of the stainless steel worm gearbox are arranged perpendicularly. A single stage can achieve various reduction ratios, and it comes with built-in mechanical self-locking capability.
Precision meshing transmission pair
The worm of the stainless steel worm gearbox undergoes quenching and tempering followed by precision grinding. The worm wheel is made of wear-resistant copper alloy, featuring high tooth profile precision and stably controllable transmission backlash.
Corrosion resistant & easy to clean
The stainless steel worm gearbox can resist corrosion from water vapor, salt water, and weak acid and weak alkaline cleaning agents, is not prone to dirt accumulation, and meets the hygiene specifications for the food and pharmaceutical industries.
Smooth operation & low noise
The tooth surfaces maintain continuous meshing with low vibration and impact, delivering stable low-speed torque output, making it suitable for long-term continuous operation in clean workshops.
Flexible installation & strong compatibility
The stainless steel worm gearbox features standardized mounting dimensions, supports direct motor connection, and enables flexible multi-orientation installation including horizontal, vertical and flange mounting.
Q:What is the protection class? Can it withstand high-pressure washing?
A:Standard version reaches IP67. Sealing structure can be upgraded to IP69K for production line CIP cleaning.
Q: Does every stainless steel worm gearbox have self-locking function?
A:Models with reduction ratio above 30 provide reliable reverse self-locking to avoid load reverse rotation after power cut. Not suitable for frequent heavy shock loads.
Q:Can food-grade lubricant be used inside the gearbox?
A:Most models share identical mounting dimensions with standard NMRV reducers for direct replacement. Please confirm specifications for special output shafts before ordering.
