Stober C402N0310MT20 Precision Helical Gear Reducer

The STOBER C402N0310MT20 Precision Helical Gear Reducer delivers a 31:1 reduction with an output speed of 56 RPM, a compact gearing solution for servo-driven machines that require precise, low-speed torque delivery. As part of STOBER’s C-series precision helical gearboxes, the C402N0310MT20 uses a one-piece cast-iron housing with precision-machined bearing supports to maintain gear alignment and withstand overhung loads, and its gears are case-hardened to 58–62 HRC for durability. The C402N0310MT20 designation encodes the C402 model family, the 0310 (31:1) gear ratio, and the MT20 motor-adapter configuration favored for servo integrations in tight packaging. Dimensional data for Unit C402/C403 lists mounting envelope values such as A = 250 mm, D = 242.5 mm, F = 215 mm, H = 142.5 mm, J = 14 mm, T = 178 mm, and V = 80 mm, which helps designers plan installation and clearance in compact automation layouts, while replacement-part catalogs confirm availability for C-series N units.
