Rotary Viscous Dampers (RVD)

Features and Benefits

Safely and quietly controls rotary motion Low initial breakaway friction for precision torque control Provides consistent speed control through 360 of rotation, in both directions Compact, shaft-ready mounting design includes anti-rotation keyway Controls linear motion through simple mechanical integration Wide range of ambient operating conditions indoor or outdoor, -20 F to +200 F (-30 C to +95 C) Customer-specified performance through 3 40 in-lbs. (0.4 4.5 Nm.) of Torque per unit

RVD expands our rotary motion control capabilities

Maintenance-free no adjustments required Rotary Viscous Dampers provide smooth control in applications that require continuous or intermittent positioning, forward, reverse and fixed path motion. The RVD design combines low breakout friction with viscous damping to control bi-directional rotary motion in numerous applications. Each RVD contains a solid, rotating element called a“rotor”. This rotor is surrounded by a thin film of silicone fluid and sealed inside a stationary housing. The RVD’s rotor provides resistance by shearing the silicone fluid, controlling the desired motion.
