40 kg·cm coreless servo pair
This two-pack supplies a matched set of JUSHIDE JS6640 coreless digital servos rated at 40 kg·cm stall torque. They suit 1/8 and 1/10 scale RC cars, crawlers, buggies, robots and marine models that demand high torque in a compact 40 × 20 × 38.5 mm case.
IP66 sealing and metal gear train
Each unit combines an IP66-rated waterproof housing, double ball bearings and a 373:1 stainless-steel gear train. The coreless motor delivers faster response and longer life than brushed alternatives, while the 2 µs dead band and programmable 180° or 270° travel allow precise setup for steering or control surfaces.
PWM range and voltage compatibility
Your controller must output a 500–2500 µs pulse width at 50–330 Hz to reach the full angular range. The servos operate on 6.0–7.4 V DC, so a 2S LiPo or 5-cell NiMH pack is required; verify your receiver and BEC can supply adequate current for two high-torque units.

Questions about this item
How often should I inspect or replace the stainless steel gears in the JS6640 servos?
The 373:1 metal gear train uses high-precision stainless steel gears and double ball bearings designed for minimal backlash and long life; inspect for wear after heavy use, but no fixed replacement interval is defined.
What limits continuous operation of the JS6640 when running at 7.4 V?
At 7.4 V the coreless motor delivers 40 kg·cm stall torque with a 0.17 s/60° speed; the IP66 seals and aluminium centre case handle heat and dust, so the practical limit is the 373:1 gear train's thermal capacity under sustained load.
How much noise and heat do the JS6640 servos produce during all-day running?
The coreless motor and stainless steel gear train are specified for low noise; the CNC aluminium middle shell and double ball bearings dissipate heat, while the IP66 waterproof seals add no extra friction during extended operation.
