Our Sew Eurodrive explosion-proof parallel-shaft helical gear units are assigned to equipment categories II2GD. A wide range of mounting positions and variants enable a broad range of applications. Gas and dust atmospheres are no problem, even under difficult conditions. All that, without having to compromise on the performance. What many of our gear units offer: long service lives without maintenance and wear-free gearing with a high fatigue strength.
With a high torque rating from 130 Nm to 18,000 Nm, our parallel-shaft helical gear units with explosion protection offer great performance in many conveying and processing applications.
You can choose between foot, flange or shaft-mounted options. For precise positioning tasks, our parallel-shaft helical gear units are available with reduced backlash.
K series Sew Eurodrive explosion-proof helical-bevel gear units
Our ATEX-compliant Sew Eurodrive explosion-proof helical-bevel gear units combine high cost-effectiveness with explosion protection thanks to their wear-free gearing and high efficiency.
Save energy the easy way: even in potentially explosive atmospheres
You want a drive solution that can be installed in a small space? One that provides reliable motion in potentially explosive atmospheres?
Then we recommend our Sew Eurodrive explosion-proof helical-bevel gear units in equipment categorie II2GD. These right-angle gear units have torques from 200 Nm to 50,000 Nm and feature a particularly compact design.
With their high efficiency in both directions of torque and at any input speed, they are also very energy-efficient.
A long, maintenance-free service life enhances this economy and efficiency. That’s why the Sew Eurodrive explosion-proof gear units K series is used in so many applications in potentially explosive atmospheres. Worldwide!
S series Sew Eurodrive explosion-proof helical-worm gear units
With higher efficiency than pure worm gear units, the Sew Eurodrive explosion-proof helical-worm gear units are particularly powerful. The II2GD version can be used reliably in many explosion-proof applications.
Particularly powerful: with impressive efficiency, even in potentially explosive atmospheres
The simple design of these gear units ensures cost-effectiveness. The individual adjustment of torque and speed allows for space-saving installation of our helical-worm gear units. Use the S series gear units to implement simple tasks in your machine or plant applications.
The combination with a helical gear stage significantly increases the efficiency compared to pure helical-worm gear units. The linear power transmission makes the worm gear units especially quiet in operation. The torque ranges from 92 Nm to 4000 Nm.
W series Sew Eurodrive explosion-proof SPIROPLAN right-angle gear units
You don’t have to sacrifice high speeds for your conveyor applications in potentially explosive atmospheres. Our compact lightweights, the SPIROPLAN right-angle gear units, are also available in an ATEX version.
Our smallest solutions: lightweight and compact, even in the ATEX version
What is special about SPIROPLAN right-angle gear units is their wear-free gearing. It ensures that the power is transmitted reliably and adjusts the speed in your materials handling system. Of course, it’s also included in the explosion-proof gear unit version: an ATEX-compliant gear unit for equipment categorie II2GD.
With this gearing, our SPIROPLAN right-angle gear units deliver output torques up to 180 Nm in the motor power range from 0.12 to 3.0 kW. The steel-steel material combination and the special tooth meshing enable a short gear unit design for space-saving installation of the drives.
It’s the details that make the difference
Thanks to their aluminum housing, these right-angle gear units are real lightweights. Their special gearing and lubrication for life ensure that they require very little maintenance. These gear units are designed for long and reliable operation. No compromises: The SPIROPLAN right-angle gear units are suitable for almost any drive task due to their many design variants.
PS.F series Sew Eurodrive explosion-proof planetary servo gear units
Our Sew Eurodrive explosion-proof planetary servo gear units provide precision, performance and reliability in potentially explosive atmospheres. They reliably transfer high speeds and torques while absorbing high overhung loads.
Explosion-proof, low-backlash planetary servo gear units: compact and reliable
Explosion protection with a compact design, high speeds and high torques: That’s what sets our ATEX-compliant planetary servo gear units apart.
Our planetary gear units reliably deliver precision and cost-effectiveness in potentially explosive atmospheres. The PS.F series offers torques from 25 Nm to 3000 Nm.
They feature a consistently low rotational clearance and high torsional rigidity. All gear ratios from i = 3 to i = 100 are integers and finely stepped. This means that these explosion-proof servo gear units in equipment category II are also especially suitable for use with controllers that require integer resolution ratios.
BS.F series Sew Eurodrive explosion-proof helical-bevel servo gear units
Our Sew Eurodrive explosion-proof helical-bevel servo gear units are ATEX-compliant and belong to equipment group II. They’re reliable, durable and low-maintenance: the ideal foundation for a wide variety of servo drive solutions in potentially explosive atmospheres.
ATEX-compliant, versatile and compact Sew Eurodrive explosion-proof gear units
Your application is in a potentially explosive atmosphere and you need torques in a range from 40 Nm to 1220 Nm? Then we recommend our ATEX-compliant, low-backlash BS.F helical-bevel servo gear units. Their permitted acceleration torque ratings are significantly higher than these values.
With six sizes and five output variants, this series is incredibly versatile. With a compact build, the BS.F helical-bevel servo gear units have a low rotational clearance, even in the standard versions. You also have the option of reducing the rotational clearance further.
