Satellite Roller Screws
PLANETARY ROLLER SCREW PRODUCTS & SOLUTIONS
What are Planetary Roller Screws?
Planetary roller screws (or satellite roller screws) are a type of screw that transfers rotational forces to a linear movement. They are an integral part of operations in the industrial, aerospace, robotics, semiconductor and scientific applications. They can handle extremely high load ratings and speeds at high efficiency, high positioning accuracy and with minimal friction.
Our planetary roller screws have a very high life span and require only minimal maintenance. This makes them an excellent choice when converting fluid power systems into servo motor drive electro-mechanical actuation. Rollvis screws are divided into 4 main product groups.
Why should i choose a Satellite Roller Screw over a ball screw?
Rollvis Swiss primary screw type, the RV, is a workhorse suitable for many applications.
The HRV roller screw is a heavy-duty version of our RV planetary roller screw, used when longer service life or higher peak loads are needed.
RVI screws make the most of small spaces. They are a popular choice for robotic arms in automotive spot welding applications.
Their unique design allows fully integrated and sealed constructions.
The RVR screw is a precision design that is often used in positioning systems in scientific applications or for precision grinding machines.
They are the best precision and stiffness combination.
Using cutting edge technology, Rollvis are the only company able to produce RVD differential roller screws.
The RVD provides unrivaled precision for the most demanding applications, offering position on a nanometer scale.
Accessory Products
BU Support Bearing Unit
Each roller screw needs to have support bearings. As a service to our customers Rollvis offer a support bearing housing made for bearing bore diameters from 12mm to 100mm. These units are populated with sets of 7300 series angular contact ball bearings which can be adjusted to meet the applications demands.

Applications for Roller Screws
Planetary roller screws (or satellite roller screws) are a type of screw that transfers rotational forces to a linear movement. They are an integral part of operations in the aerospace, robotics, semiconductor, and scientific industries. They can handle extremely high load ratings and speeds at high efficiency, high positioning accuracy and with minimal friction. Planetary roller screws are well-suited to applications that require high peak loads or high speeds. They are also a good choice for customers who seek a product requiring minimal maintenance.
