VRL High Precision Planetary Gearbox

Features of MKD VRL Planetary Gearbox

High precision

Backlash is less than 3 minutes (0.05°) with high precision positioning, which can give full play to the performance of the servo motor.

High rigidity & high torque

The use of integral roller bearings highly improves rigidity and torque.

High load capacity

The main shaft adopts tapered needle roller bearings to achieve high load capacity.

Flange & output shaft method

The use of the flange and output shaft method has simplified the connection with the equipment, and the gearbox can be installed on any brand of servo motor and stepper motor.

No grease leakage

The use of high-viscosity non-separable grease has effectively prevented grease leakage.

　High protection

The IP65 protection grade is adopted to adapt to any harsh environment.

Long life & easy maintenance

The users don’t need to change the grease during the service life of 20,000 hours of the gearbox, so it is more worry-free.

Description of VRL High Precision Planetary Gearboxes

VRL series speed reducer is a kind of inline planetary gearbox with good accuracy and high reliability. If the high precision operation is required, our VRL is a good choice for you. Thread-in mounting method together with a high level of precision and torque capacity make VRL speed reducer the best among similar products. Supplied with a coaxial shaft design, MKD VRL planetary gearbox is featured with 2~5 arcmin low backlash class, can meet your various needs of accuracy.

Full dimensions of VRL series make it can directly replace the similar model of other brands on the market. High quality of machined planetary helical gears contributes to VRL reducer run more quietly and more effective. These series of VRL planetary reducers are widely used in injection moulding machines, linear slides, pick and place automation, gantries, cutting and welding machines, etc. They are the perfect solutions for servo motor application.

MKD planetary gearheads are manufactured under the industry standard. They are easy to handle and available at a very competitive price.

How to Select the Right Speed Reducer?

Step 1

What’s your motor brand and model? Or you can offer us the motor mounting dimension drawing like the following drawing with key sizes LR, LE, S, LB, LZ, LA

Step 2

What’s the ratio you need? Or pls tell us the nominated speed of your motor and the output speed of gearbox that you want.
＊The speed ratio i=Motor Speed /output speed of the gearbox

Step 3

What’s the output torque you need? Or pls tell us the power and the nominated speed of the motor.
＊The output torque (N.M)=9550x motor power(kW)/ motor speed (rpm)
＊1 HP=0.75kw

Step 4

What’s your other requirement about the gearbox? Such us flange, hole output, precision or backlash, noise value, the shape of the gearbox, inline or angle, etc. The more details requirement you offer us, the quicker we can select the suitable speed reducer gearbox for you.
