Overview
The SMC RBC2725 shock absorber is a precision-engineered accessory for RB Series pneumatic systems. This with-cap variant delivers reliable impact absorption and noise reduction in automated machinery, with a 25 mm stroke and M27 x 1.5 port configuration. Designed for high-energy applications, the RBC2725 automatically adjusts to optimal performance across a range of impact speeds (0.05–5.0 m/s).
Key Features
- High Energy Absorption: 147 J capacity handles serious impact loads with maximum allowable thrust of 2,942 N
- Compact Design: Shortened lengthwise profile simplifies integration into tight spaces
- Automatic Performance Adjustment: Self-regulating damping optimizes absorption across varying impact speeds
- Cap Protection: Durable cap shields the absorber piston and extends service life
- Wide Deviation Tolerance: Allows up to 5° mounting angle without performance loss
- Robust Construction: Can be mounted directly without external stoppers
