Description

The NEMA23 PX57 (57mm) Series Planetary Gearbox is a high-precision motion control solution designed for stepper motors. With a compact 57 × 57 mm / 60 × 60 mm housing and 8 mm input shaft, it integrates seamlessly with NEMA23 and NEMA24 stepper motors.

Belonging to the HPS series, this gearbox provides gear ratios of 5:1, 10:1, 24:1, 50:1, and 100:1, delivering optimized torque and speed reduction for robotics, CNC machines, 3D printing, packaging machinery, and other automation systems requiring accurate and reliable motion.

With rated torque ranging from 15–40 N·m, maximum torque up to 50 N·m, and backlash ≤50 arcmin, it ensures smooth, precise, and dependable operation. Built with hardened alloy steel gears, precision bearings, and an input shaft coupling, it offers high efficiency (85–95%), low noise (≤60–75 dB), and a long service life of 20,000 hours.

The PX57 Series is engineered for inline mounting, compact design, and durability, with IP65 protection, making it suitable for demanding industrial and automation applications.
