R-SERIES
Radial Bumper Solutions
/// R-Series Overview
Compressed radially, these dampers provide a longer, softer deceleration. Easily mounted to any surface, these general-purpose dampers can handle off-axis loads and high vibration conditions.
- Maximum energy absorption ranges from 15 to 3,750 in-lbs. [2 to 424Nm]
- Maximum travel ranges from 0.59 to 2.36 in. [15 to 60mm]
- Damping efficiency up to 60%
