No. S Series belongs to the R/F/K/S modular gear reducer family and uses a helical-worm structure. NMRV / RV is a compact worm gear reducer family. Both can serve right-angle layouts, but they belong to different product platforms.
S Series uses a helical-worm structure and is more suitable for compact and economical right-angle drive positions. K Series uses helical-bevel transmission and is more suitable when higher efficiency and stronger right-angle torque capacity are required.
S Series is a right-angle helical-worm reducer. R Series is an inline helical reducer. Use S when the drive path must turn 90 degrees, and use R when the motor and driven shaft remain in a straight layout.
S Series is a right-angle helical-worm reducer. F Series is a parallel shaft helical reducer. Use S when the shaft arrangement is perpendicular, and use F when the shafts need to stay parallel.
Yes. S Series can be reviewed with hollow shaft, flange, B14 hollow shaft, and torque arm configurations according to the selected model and drawing.
Yes. S Series can be supplied as a geared motor package. Motor options may include standard motor, brake motor, variable-frequency motor, multi-speed motor, and other confirmed configurations.
A variable-frequency motor or inverter-compatible motor package should be reviewed when speed control is required. SV200 frequency converter and YVF motor options can be checked as part of the drive package.
Send motor power, input speed, required output speed, ratio, output torque, mounting form, shaft form, hollow shaft bore if required, torque arm requirement, duty cycle, and working environment. For replacement, include the old nameplate and installation drawing.
2D drawings and 3D CAD files can be requested after reducer size, ratio, mounting form, output shaft, motor option, flange requirement, and installation direction are confirmed.
