Low backlash planetary gearheads

Economy

Generation 3

Innovation sets standards

The low-backlash LP

Generation 3 planetary gearhead

extends and completes the product portfolio.

· Up to 75% higher torques
· Noise level halved
· New ratios for optimum solutions
· Maximum quality and reliable availability

LPB

Generation 3

Innovation sets standards

The low-backlash LPB

Generation 3 planetary

gearhead with flange output is the logical extension
of the current product range. The Generation 3 offers:

· Compact and intelligent solutions for your drive
· Two-stage version for maximum ratio flexibility

Versatile installation

In whatever position you install your gearhead,
it

always contains the same quantity of grease.

The gearheads are so flexible, you can install them
vertically, horizontally or with the output facing
upwards or downwards.

Extended boundaries

Our Economy range includes some impressive new
additions. In the 070, 090 and 120 sizes, our LP

/LPB

Generation 3 gearheads feature up to 75% more
torque, independent of the ratio!

Simple precision

The alphira

gearhead combines proven

gearing technology with the cost-effec-
tiveness requirements in the economy
servo sector.
Ideal for simple servo applications.
Available from our online shop
