Mounting
Foot, B5/B14 flange, shaft-mounted, torque arm. Left/right outputs.
Protection
IP55–IP66, Viton seals, breathers, heaters & low-temp oil options.
Testing
Run-in, backlash check, vib/noise, oil sample & paint thickness report.
Torque Where You Need It
- Right topology: planetary for compact high-torque; helical-bevel for efficient 90° turns; parallel helical for CT/LT; worm for quiet low speed.
- Duty matched: service factors for M4–M6, starts/h & ambient folded into selection.
- Integration: geared motors with brakes, encoders, backstops & torque limiters.
- Maintenance: drain/fill plugs, inspection windows, lubrication matched to climate.
