DFRobot High Torque Waterproof Metal Gear Digital Servo (35KG, 180°, IP54)
Boasts 35kg torque capacity with 180° motion
Features dual ball bearings for smooth operation
Includes IP54 waterproof rating for durability
Automatically protects against overheating
Equipped with steel gears and aluminum casing
The DFRobot High Torque Waterproof Metal Gear Digital Servo (35KG, 180°, IP54) is a robust and versatile digital servo designed for demanding applications. It features a torque capacity of 35kg and a controllable angle of 180 degrees, providing superior linear motion. The internal configuration includes steel gears with a thickened gear axis, optimized to a 2.0 center distance, and a dual ball bearing design that ensures smooth operation. The aluminum casing enhances heat dissipation, thereby extending the servos lifespan.
This servo is equipped with electronic and temperature protections to ensure safe operation. In the event of a servo lock-up, it automatically triggers a protective torque output if the torque exceeds the overload capacity for more than 8 seconds. Additionally, if the servos temperature exceeds 70 degrees, it ceases torque output and resumes only when the temperature drops below this threshold.
Enhanced water resistance is achieved through fortified joints with waterproof gaskets, a circuit board coated with waterproof varnish, and specialized adhesive sealing for both the motor and potentiometer. These features contribute to the servos exceptional waterproof capabilities. The servo also comes with various servo horns, allowing for a broader range of applications.
Note: Ensure proper usage to avoid overheating and mechanical lock-up.

A valid Return Authorisation (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A £100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables * — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tyres, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odour-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly * — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps * — Final sale only, due to licensing restrictions.
Clearance Items * — Products identified as clearance or final sale, including end-of-life or discontinued items.
