AGFRC SA81BVMW 48Kg High-Torque Digital Brushless Servo
In stock: ships within 2 business days.
Low stock: lead time confirmed upon order.
Delivery: 4–9 days after shipment.
AGFRC SA81BVMW is a 10–14 V programmable waterproof servo with 180° travel, magnetic angle sensing, IP67 protection, and a 25T spline for high-load RC and robotic systems.
➤ The SA81BVMW is a high-torque digital servo for RC vehicles, robotics, and compact mechanical systems that require strong output and responsive position control. At 10–14 V, it provides up to 48.0 kg·cm of stall torque at 14.0 V and reaches 0.095 sec/60° at 14.0 V. A brushless motor, FET drive, magnetic angle sensor, 2 μsec dead band, and 333 Hz refresh rate support fast, programmable servo operation.
➤ Its aluminum case, high-strength steel gears, metal bearings, and IP67 protection make the SA81BVMW suitable for demanding installation environments. The servo offers 180° ±10° operating travel, a 40 × 20 × 37.5 mm body, and a 25T Φ5.92 mm spline for integration into high-load RC models, robotic mechanisms, pan-tilt systems, and OEM equipment.
