Energy is expressed in joules: 1 J = 1 N·m. Effective mass and impact velocity must be evaluated together with the energy ratings; the largest listed mass must not be assumed to operate at the highest listed velocity.
For selection, include the moving load’s kinetic energy and any work performed by a driving force during deceleration. Check both energy per impact and total energy absorbed per hour.
Product Features
Hydraulic Impact Absorption
Hydraulic resistance absorbs energy as the moving component acts against the piston rod. This helps control deceleration over the available stroke.
Reduced End-of-Travel Impact
When correctly selected and installed, the unit helps reduce the impact transmitted to machine stops, fixtures and supporting structures.
Compact Threaded Body
External mounting threads allow installation in suitable threaded holes or brackets. Six thread sizes provide options for different mechanism sizes and mounting spaces.
Multiple Stroke Options
Strokes from 6 to 25 mm support different stopping distances. Select the stroke together with the model’s energy capacity and operating velocity range.
Standard and -N Versions
The published range includes standard and -N model designations. Review the matching dimensions and contact arrangement before confirming the required version.
Published Ratings for Repeated Operation
Per-cycle and hourly energy ratings help assess both individual impacts and repetitive operation. This is particularly useful when reviewing high-frequency automation cycles.
Applications
Automated Assembly Equipment
Helps cushion moving slides, positioning units and transfer mechanisms as they approach a defined stopping point.
Pneumatic Cylinder Mechanisms
Provides external hydraulic impact absorption where required by the moving load and machine design. Include cylinder thrust acting during deceleration when selecting the model.
Material Handling Systems
Suitable for evaluating controlled stopping of moving carriers, workpiece transfer devices and handling fixtures.
Can be integrated into reciprocating mechanisms and transfer assemblies operating within the selected model’s energy and velocity ratings.
Robotic Peripheral Equipment
Supports impact control in auxiliary handling devices, linear stops and fixtures used around robotic production equipment.
Special-Purpose Machinery
Offers a compact buffering option for dedicated machines requiring repeated linear impact absorption.

FAQ
What is an RBC hydraulic shock absorber?
It is an industrial hydraulic device used to absorb impact energy and decelerate moving machine components over a defined stroke.
How do I choose the correct RBC model?
Check the required stroke, total energy per impact, impacts per hour, effective mass, impact velocity and mounting dimensions. All operating conditions must fall within the selected model’s ratings.
Can I select a shock absorber using moving mass alone?
No. Impact velocity strongly affects kinetic energy. Any driving force acting during the stopping stroke must also be included.
What is the difference between energy per cycle and energy per hour?
Energy per cycle limits the energy absorbed in one impact. Energy per hour limits the accumulated energy from repeated impacts and is important for evaluating operating frequency.
Can the maximum listed mass operate at the maximum listed velocity?
Not necessarily. The resulting energy must remain within the model’s per-cycle capacity, and the application must satisfy the other selection limits.
Are the standard and -N versions dimensionally identical?
No. The dimension table lists differences between versions. Confirm the full model designation and matching drawing before ordering.
Does the RBC series require compressed air?
No compressed air connection is required for the hydraulic damping function. The unit may be installed alongside pneumatically driven equipment.
What is the operating temperature range?
The published range for the listed HOMIPNEU RBC models is 0–66°C.
Can a hydraulic feed controller replace an RBC shock absorber?
These products serve different primary purposes. A shock absorber is selected for impact absorption, while a hydraulic feed controller regulates motion during a working stroke. Choose according to the mechanism’s actual requirement.
