The NEMA17 JK42HS48 Stepper Motor is a high-torque, precision stepper motor built for demanding motion control applications. With a holding torque of 5.5kg·cm, it delivers powerful, stable performance ideal for 3D printers (especially heavy-duty axes), CNC routers, robotic arms, and automation systems. Featuring a 1.8° step angle (200 steps per revolution) and 4-wire bipolar configuration, the JK42HS48 ensures high positional accuracy, low vibration, and reliable long-term operation. Its 48mm body length provides extra torque while maintaining the standard 42mm NEMA17 frame, making it compatible with most mounts and brackets. Whether you are building a new machine or upgrading your current setup, this motor gives you the strength and precision you need.
