Standard 40 x 20 mm servos from 6 to 22 kg-cm of stall torque, up to 25 kg-cm at the higher voltage rating, with metal gears and brushless iron-core motors. Analog and digital drives plus sealed variants make this the direct-replacement line for OEM builds, education kits and general control duty.
Most OEM and replacement requests are not exotic: a 40 x 20 mm case, a PWM signal, enough torque margin, and a price that survives a volume build.
Every model uses the industry-standard 40.5 x 20 x 38 mm case, so existing brackets, panels and servo horns keep working when a unit is replaced.
The signal input matches mainstream receivers, controllers and microcontroller servo libraries, so no protocol work is needed at integration.
One model is analog, four list both analog and digital drives in the same case, and the two highest-torque sealed models are digital, so the drive electronics can follow the duty cycle rather than the mount.
Four of the seven models are the sealed W variants for splash, rain and washdown duty such as outdoor mechanisms, boats and crawling models.
This line is engineered for predictable supply and predictable field behavior, which is what a replacement part actually needs.
All seven models use a brushless iron-core motor, so the service interval is set by the gear train rather than by brush wear.
Every model in the line lists a metal gear set, chosen for shock load and backlash retention in general-purpose service.
Torque and speed are published at 6.0 V and again at 7.4 V on the unsealed models and 8.4 V on the sealed ones, so the figure you design with matches the supply you ship.
From 6 to 22 kg-cm inside the same case shape, so a torque revision does not force a mechanical re-design.
Each unit is inspected before shipping and the warranty term is stated in the commercial terms, so a distributor is not carrying the quality argument alone.
Sealed variants are documented per model rather than sold on a series-wide rating, so the file matches the part you are certifying.

Rated torque is the continuous-duty working value; stall torque is the peak mechanical limit and stays the sizing reference. Model codes shown with a brand prefix placeholder. Photos, simplified dimension drawings and datasheet links are placeholders; real assets will be added before launch. Detailed CAD files are factory-confidential and are not distributed. Custom codes, packaging and labeling are available under our OEM / white-label program. Stall current is not listed in the factory record for this line; supply and wiring sizing data is provided per model on request. A dash means the value is not listed in the factory record for that model.
Four ways to narrow the line: drive type, torque at your supply voltage, sealing, and how much duty cycle the mechanism sees.
Entry-level surface and latch control for educational kits, model swaps and low-cycle OEM mechanisms at the most economical price point.
General steering and surface duty on 1:10 and 1:12 models, plus the common replacement class for indoor equipment.
The same case with sealing for splash, rain and washdown: boats, crawling models and outdoor machinery.
Digital sealed drives for heavier steering, larger surfaces and frequently cycled industrial mechanisms.
Send the servo you are replacing, the torque it has to hold, the supply voltage and the quantity per shipment. We can match case size and drive type, and flag where a sealed variant is needed.
