ROSTA Tensioners
Lovejoy ROSTA tensioners operate according to the ROSTA rubber torsion spring principle. Four natural rubber inserts inside the base isolate the tensioning arm, while providing continuous resistance to rotary forces applied to it. The tensioning arm is designed to deflect up to 30° either side of its neutral position.
Features and Benefits
- Automatic tensioning operation
- One bolt central mounting — front or back
- Infinitely variable pretension positions
- Complete size range
- Corrosion resistant
- High temperature and oil resistant options
Applications That Best Fit ROSTA® Tensioners
- Belt and roller chain tensioning
- Hold-down devices
Styles Available
- Front or Rear Mount
- High Temperature
- Oil-Resistant
- Stainless Steel

ROSTA® Motorbases
The ROSTA® Motorbases utilize a large element as a swivel or pivot mount for the electric motor V-belt drive. It provides not only the proper initial belt tension and a self-adjusting motion to accommodate belt stretch, but also the ability to dampen harmful vibrations.
Features and Benefits
- Self-adjusting
- Maintenance free
- Overload proof
- Non-slip
- Dampens harmful vibration
- Extended belt life
- Most NEMA frame sizes available
Applications That Best Fit ROSTA Motorbases
- The ROSTA elastic tensioning motor base compensates continuously for all movement.

ROSTA® Elements
ROSTA offers a complete line of multi-purpose elastomeric elements that can solve most types of tensioning, suspension, and vibration absorption problems in all field of mechanical engineering.
Features and Benefits
- Silent, maintenance free operation
- Multi-function use reduces your assembly costs
- Resistance to corrosion
- + or -30 degree torsional angle enables universal spring movements – components can be combined for an even greater range of motion
Applications That Best Fit ROSTA Elements
- The ROSTA machine component may be used in any application that requires dampening, oscillation, deflection, and guidance.
