Miki pulley Rosta suspension unit DK model DK-A-18-50

- Rubber Spring The basic form of the Rosta is a suspension unit.
- It has a unique and simple structure with cylindrical rubber pressed into the inner and outer shells of metal, and is a multi-purpose machine element that can be used freely in industrial machinery, transportation, play equipment, and amusement areas. Spring function
- Torsion angle can be tolerated up to ±30°.
- The spring characteristics are nonlinear, and the torsional rigidity increases with increasing load.
- The torque characteristics are determined by the length of the Rosta.
- It is possible to support loads in all directions, including tension, compression, and shear loads. Damper function
- The internal friction of the pressed-in cylindrical rubber is more than 1000 times that of metal (spring steel). Therefore, it is possible to reduce the amplitude during resonance and to stop vibrations caused by impact early.
- It can be used as a buffer device, vibration insulation, and vibration-proof support. Bearing function
- It is possible to transmit high-frequency sliding motion while absorbing vibration.
- Normal bearings are inferior in durability when transmitting sliding motion or when lubrication is insufficient. Instead of these ball bearings and needle bearings, ROSTA's bearing function can be used without the need for daily maintenance.
