Roller chains
We have a very wide range of standard chains which are supplemented with a number of customer-unique chains. Read more about our products here.
Spinea Twinspin backlash-free cycloid gears represent a completely new generation of transmission solutions with the highest precision. They are based on a patented construction consisting of axial and radial bearings.
The term "bearing gear" points to the unique integration of a backlash-free gear with radial and axial bearings into a compact unit with many areas of application.
Twinspin's bearing gear is capable of absorbing both radial and axial forces without extra bearings and can be used directly as a connection mechanism in e.g. a robot axis.
Because the design does not contain gears like traditional planetary gears, it has much less backlash – typically less than 1 arcmin. The lifespan is also considerably longer with the clearance maintained.
In the category of small backlash-free gears, the m-series represents the best the market has to offer. Currently, size 50 is available, but in the near future we will present additional smaller sizes.
Please contact our sales staff for more information on when these are available.
This series represents the standard range with the basic advantages of the construction.
This series is available in 8 different sizes for nominal torques from 37 Nm to 2940 Nm.
Gap less than 1 arcmin
This series is a variant of the T series which is fully sealed and oil filled. Completely maintenance free.
In 7 different sizes with nominal torque from 50 Nm to 1250 Nm. Gap less than 1 arcmin.
Can easily be fitted with a motor flange for the selected motor type. 4 different variants of output shaft type and customized solution.
A development variant with a large central hole for cable penetrations with air, electricity, water, etc.
Completely sealed and oil-filled to be completely maintenance-free.
Available in 5 sizes for nominal torque 250 Nm to 2750 Nm.
It is supplied in two variants, one with a sealed output or as a fully sealed gear for direct connection with a motor.
In the new generation, we have concentrated the results of several years of development in the design and construction of the gearbox, together with the implementation of the latest manufacturing processes and technologies.
Spinea DriveSpin is a compact combination of servo motor and Twinspin backlash-free robot gears.
The advantages are obvious:
Rotospin A is developed for manipulators where the requirements for repeat accuracy and positioning are high and where the passage of cables, hoses, etc. is done on the opposite side of the manipulator.
They can transmit large torques and handle very high radial loads.
The base consists of a Twinspin robot gear equipped with two flanges, one of which rotates and the other connects to the stand construction. The delivery can be made with or without a servo motor, but is always adapted to the current motor.
Rotospin B is developed for manipulators where the requirements for repeat accuracy and positioning are high and where the passage of cables, hoses, etc. is done on the opposite side of the manipulator.
They can transmit large torques and handle very high radial loads.
The base consists of a Twinspin robot gearbox fitted with a standard flange on the output side. The unit is then mounted in a housing that allows direct mounting to a suitable stand construction. The delivery can be made with or without a servo motor, but is always adapted to the current motor.
Rotospin storage unit series C is without robot gear and is intended to be used as a storage unit where two storages are required.
Their dimensions correspond to series A, B and C for easy assembly.
They provide the opportunity for the passage of cables, hoses, etc.
We have a very wide range of standard chains which are supplemented with a number of customer-unique chains. Read more about our products here.
Wire race bearings are a unique construction with ring-shaped raceways made of steel. They are intended for installation directly in the basic structure, which thus replaces the bearing rings in a conventional bearing.
With Rossi's product range, we have the world's widest range of gears. Here you will find gears that are included under precision.
