CNCTOPBAOS NMRV040 Worm Gear Reducer Gearbox 10:1 for Nema34 Stepper Motor
5 sold in last 24 hours
- NMRV40 10:1 Speed Ratio Worm Gear Reducer - Model NMRV040 RV40 worm gearbox with 10:1 speed ratio, engineered for smooth speed regulation and dependable torque amplification, perfectly matched with Nema34 stepper motors and Nema34 servo motors. Ideal for general industrial automation lines, conveyor systems, rotary tables, packaging machinery and heavy-duty transmission applications
- Standardized Nema34 Mounting & Exact Shaft Specifications - Features an 86mm x 86mm (3.38" x 3.38") standard Nema34 flange with 73mm (2.87") spigot length and 95mm (3.74") diagonal pitch, paired with a 14mm (0.55") input bore diameter and an 18mm (0.7") output shaft diameter. It supports multi-faceted installation for flexible layout, ensuring seamless assembly and full compatibility with most mainstream Nema34 stepper/servo motors on the market
- Premium Material Build for Durability & High Load Capacity - Crafted with a high-quality aluminum alloy enclosure for excellent thermal dissipation, high rigidity and corrosion resistance. Internal core components include a hardened high-quality steel worm, 94 copper worm gear, KSK oil seal and high-grade bearings, delivering large load-bearing capacity and effectively extending the service life of the gearbox
- Smooth Transmission - Adopts a hardened worm gear set and high-grade bearings, providing stable power transmission with low operating noise and reliable overheating resistance for long-term continuous operation. As with all standard worm gearboxes, this unit has some normal gear lash inherent to the worm drive design — acceptable for general load driving and speed control. It is not intended for precision machining or high-accuracy positioning applications
- Wide Compatibility with Critical Selection Notes - Adapts to a variety of automation scenarios: CNC router auxiliary axes, engraving machines, conveyor belts, sorting lines, automatic packaging machines, DIY robotic arms, small industrial robot joints, rotary indexing tables, automatic feeding devices, filling machines, labeling machines, woodworking and more. Please Note: This gearbox is reversible (non-self-locking) — the output shaft can turn the input shaft under back-drive loads
