Helical-bevel gear units from SEW‑EURODRIVE provide a high degree of efficiency of over 90% in both torque directions and at all input speeds. With performance designed to last – high-endurance gearing enables high-torque, wear-free operation. The remarkably high degree of efficiency makes our helical-bevel gearmotors energy-saving angular drives. Their long maintenance-free service life makes them suitable for applications with AC asynchronous motors as well as with asynchronous and synchronous servomotors. For particularly precise positioning tasks, the K37 to K187 series is also available with reduced backlash. Available variants: Foot- or flange-mounted B5 or B14 flange Solid shaft or hollow shaft Hollow shaft with keyed connection, shrink disk, splined hollow shaft, or TorqLOC®®
