Standard Roller Screw (SRS)
The SRS roller screws are high precision mechanisms with robust design. Planetary rollers do not recirculate enabling stable driving torque and motion control. These roller screws can be used under very high speed and acceleration conditions and will give a very long and reliable life thanks to their very high capacity ratings. This design offers multiple possibilities to downsize as the load performance is achieved is a very small space envelope.
The SRS range starts from diameter 4mm up to 120mm with various leads and nut options. Cylindrical or flange nuts are part of the standard designs but many customs designs are possible. Please consult our engineering team.
A wide range of leads are possible and linear speeds up to 2.5m/S can be achieved on some designs. SRS roller screws are universal and are often the best choice for many different.
