Creality 3D 42-34 Stepper Motor with Round Shaft

With a holding torque of 0.4 Nm and a precise 1.8° step angle, this Creality 42-34 stepper motor delivers the reliable motion control your 3D printer needs for crisp, accurate prints. Its round 5 mm shaft and standard NEMA 17 frame make it a direct fit for many popular Creality models, while the 4-pin JST-XH connector ensures simple, secure wiring.

Overview

The Creality 3D 42-34 Stepper Motor is a high-performance 2-phase bipolar stepper motor engineered for 3D printing applications. With a body length of 34 mm and a NEMA 17 mounting pattern (42 mm × 42 mm), it is ideal for driving the X, Y, Z axes or the extruder on a wide range of Creality 3D printers. Its 200 steps per revolution provide smooth, precise movement, and the round shaft design offers flexibility for different pulley or gear setups.

What stands out

• High torque output: 0.4 Nm holding torque ensures reliable positioning even under load.
• Precise stepping: 1.8° step angle (200 steps/rev) for fine detail and smooth motion.
• Standard compatibility: NEMA 17 frame and 4-pin JST-XH connector fit most Creality 3D printers.
• Durable construction: Class B insulation and operating temperature range of -10°C to +50°C for consistent performance.
