Asynchronous gear-motor K_D / K_TA series

servomotorhelical gearspiral bevel

Product overview
Helical bevel (angular) gear units Series K provide torque transmission for right-angle drive arrangements. They are designed for compact installation where space is limited and deliver high efficiency across a wide torque range (approx. 55–12,200 Nm). Combined with suitable drives, input powers up to 45 kW can be achieved. Double-sided output shafts and multiple housing variants are available to suit various industrial mounting requirements.

Motor adapters

• IEC motors
• NEMA motors
• Servo motors

Highlights

• Multiple output shaft and housing versions
• Double-sided output shaft option
• Reinforced bearings for heavy loads
• Improved sealing for harsh environments
• Low gear backlash for precise positioning
