KEB's helical bevel gearmotors offer a compact and highly efficient solution for right-angle power transmission. Designed for demanding applications requiring reliable, continuously high output torque, our gearmotors are fully customizable to meet a variety of industrial needs.
With configurations for solid output shafts and hollow bores, these gear units excel in hoisting, cycling, and many other industrial applications.
Integral design provides a compact design and lower weight compared to flanged designs.
KEB’s high-quality two and 3-stage helical bevel gearmotors offer 94-96% efficiency.
Gearmotors can be supplied with solid output shafts or hollow bores.
KEB gearmotors excel in demanding hoisting and cycling applications.
Designed to work with a failsafe spring-applied brake. Configure with a hand release, micro switch, or noise dampening.
Helical bevel gearing can be added to a PM servo motor or an induction motor (IE2 & IE3).
• Output Torque: Up to 15,000Nm
• Brake Option: KEB Spring-set Brake
• Backlash: 10-20 arm/min. as standard. Low backlash option exists
• Protection Type: IP55 standard. Up to IP65 available.
• Maximum Ambient Temperature: 40° C with possible derate
• Elevation: 1000m rated with possible derate
Spring-set Brakes: Add a spring applied (spring-set) brake to your gearmotor. KEB COMBISTOP Spring Set brakes provide failsafe braking functionality with boosted coils for higher torque and a robust design for tough industrial applications.
KEB brakes provide power-off brake engagement. The brakes used are KEB’s Type 38 brake which includes common options like a manual hand release and micro switch. A quiet brake is available for theatre and stage applications.
Feedback devices
KEB motors can be configured with feedback devices. Common formats include: TTL, HTL, resolver, BiSS, and Hiperface.
Customized outputs
KEB can provide gearmotors with custom flanges or shafts to facilitate mounting to the machine. It is also possible to provide an output flange or shaft on both output sides.
Food Grade Lubricants
For use in food production, KEB gearmotors can be provided with food grade lubricants and greases.
Extra Environmental Protection
For use in washdown or corrosive environments, the gearmotors can be supplied with extra paint protection and seals.
Many engineers initially opt for worm gearmotors because of their lower upfront cost. However, worm gearing is significantly less efficient than helical bevel gear units. Worm gears typically operate with around 80% efficiency, while the KEB helical bevel gearmotors achieve over 90% efficiency.
This higher efficiency translates into multiple operational benefits:
Lower energy consumption – Significant savings in energy costs over the lifetime of the motor.
Less heat generation – Less energy is lost to heat, increasing the longevity of the motor.
Reduced noise – Quieter operation compared to worm gears.
These advantages allow smaller motors to achieve the same output torque, ultimately optimizing both performance and cost over the long term.
KEB helical bevel gearmotors are highly versatile and customizable for various applications, including: industrial door lifts, theater hoists, cable drum drives.
Our gear units can be configured for foot or flange mounting, and we offer custom flanges and solid or hollow output shafts to meet specific requirements. The bevel gear design provides a right-angle output, making it ideal for confined spaces.
For applications requiring dynamic or holding brakes, we offer spring-set brakes on the non-drive end. For precise positioning, choose from incremental or absolute encoders, and for washdown applications, our gearmotors are rated up to IP65.
Our helical bevel gearmotors are available in sizes ranging from .25hp to 50hp. Whether your application requires a compact solution or a high-torque setup, KEB can provide the right motor configuration, along with complementary options like:
We can add our spring-applied brake solution to the non-drive end of the motor for applications requiring dynamic braking or secondary holding brake functionality. For hoist and theatre applications, we can also mount a load brake onto the output of a helical bevel gear motor.
We offer incremental and absolute encoders for applications where precise positioning is essential. Additionally, we provide an IP65-rated gearmotor solution for washdown environments to ensure protection against dust and water ingress.

Although the initial cost may be higher for the helical bevel gearmotors, the long-term operation costs will be higher if you select a worm gearmotor. You will pay much higher energy costs since the worm gearmotor is less efficient than the KEB helical bevel gearmotor.
With the increasing global focus on energy efficiency, IE3 motor efficiency standards are becoming more prevalent. KEB is ahead of the curve, adapting our electromagnetic designs to meet these evolving standards in both Europe and North America.
Rising energy costs make efficiency an important factor in choosing motors, and KEB’s helical bevel gearmotors maximize energy savings.
