Waterproof Lead Screw Linear Module

Waterproof Lead Screw Linear Module is a precision mechanical device that integrates the screw transmission mechanism, guide components, and protection system. It can achieve linear reciprocating motion in humid, dusty, liquid splashing, or lightly soaked environments. The protection level usually reaches IP65 or above (can withstand low-pressure water spray), and some high-end models can reach IP68 (short-term underwater immersion). Compared with ball screw modules, Waterproof Lead Screw Linear Module uses trapezoidal screws or other screws as the core transmission components, focuses on cost control and stability under low-speed conditions, and is suitable for scenarios with medium precision requirements but clear protection requirements.

Working principle of Waterproof Lead Screw Linear Module

The core is the spiral meshing transmission of the screw and nut: when the motor drives the screw to rotate, the nut converts the rotational motion into linear

motion due to the constraint of the spiral groove, driving the load to translate along the guide rail. Waterproof design is achieved through multiple seals - the screw shaft end uses lip seals or V-shaped combination seals to block liquid intrusion; Install a retractable dust cover (such as a corrugated pipe) or a labyrinth seal structure at the gap between the nut and the module housing, and the surface of the screw is often coated with anti-corrosion coatings (such as galvanized or PTFE) to prevent rust from affecting transmission efficiency.

Structural composition of Waterproof Lead Screw Linear Module

Transmission core: trapezoidal screw (medium precision, good self-locking) or TallMan screw (strong load-bearing capacity), paired with composite material

nuts (such as PTFE filled nylon, wear-resistant and does not require frequent lubrication).

Guidance system: usually sliding guide rails (low-cost) or cylindrical guide rails, some models use linear bearings to assist in positioning and ensure smooth

movement.

Protective components: shaft end seals, bellows dust covers, shell sealing strips, and some models add waterproof joints at the motor interface.

Drive unit: Equipped with multiple stepper motors or DC reduction motors, the connection between the motor and the module is connected through a waterproof coupling to prevent liquid from seeping along the motor shaft.

What are the application scenarios of waterproof screw linear module?

Waterproof screw linear module, with medium precision, good waterproof and dustproof capabilities, and cost advantages, is widely used in scenarios with clear protection requirements but not extreme precision requirements, mainly including the following fields:

Light industry production: Sauce filling and beverage bottle cleaning assembly line in food processing, which can resist liquid splashing and cleaning agent erosion; The component handling mechanism for the assembly line of household appliances such as washing machines and dishwashers is suitable for the humid environment in the workshop.

Agriculture and aquaculture: irrigation nozzle moving device for greenhouse, tolerant to irrigation water and dew; The water quality monitoring equipment for aquaculture ponds has a translation mechanism to resist splashing and high humidity corrosion caused by pond water.

Outdoor and municipal equipment: Track drive system for solar photovoltaic panel cleaning robots to cope with rainy and snowy weather; The lifting and

adjusting mechanism of outdoor advertising light boxes and traffic signal lights can resist natural precipitation.

Low end water treatment: The valve opening and closing drive of small sewage treatment equipment, the translation component of sedimentation tank

scraper, can withstand the contact of sewage steam and a small amount of liquid.

Warehousing and Logistics: Shelf pushing devices in damp warehouses and auxiliary sorting mechanisms for goods in cold chain logistics under low

temperature and high humidity environments to prevent condensation from affecting transmission.

The core advantage of Waterproof Lead Screw Linear Module lies in balancing protective performance and cost, suitable for low-speed and low-frequency motion scenarios, especially in working conditions that do not require high-precision control but need to avoid corrosion or jamming caused by moisture.
