Pneumatic stopper cylinders with shock absorbers for soft, rebound free stopping of conveyed load weights of up to 1700kg and speeds of up to 45 m/min. The robust lightweight aluminium diecast body offers a compact size enabling the unit to be installed vertical and horizontal in multiple conveyor systems.
■ STVSR series - Integrated shock absorber for heavy conveyed loads: The built-in shock absorber stops the conveyed load in a gentle and precise manner without disturbing the load. Various shock absorbers are available depending on the weight of the conveyed load and the desired transport speed.
■ STVDR series - Roller for lower conveyed load weights: The piston rod with upward facing roller is lowered by applying compressed air once the conveyed load is on the ground. Afterwards, it is brought back into the upper end position by a return spring.
■ STVD series - Direct stopping piston rod for heavy conveyed loads: Reliably stops heavy conveyed loads at low transport speeds. Can also be used as a locking cylinder due to its solid piston rod.
■ STHSR series - Horizontal stop cylinder with shock absorber: Reliably stops heavy conveyed loads at high transport speeds. Well-suited for buffer areas.

• Hydraulic industrial shock absorbers for soft, rebound free stopping of conveyed load weights
• Various shock absorbers are available depending on the weight of the conveyed load
• Direct stopping piston rod (STVD series) reliably stops heavy conveyed loads at low transport speeds
• Solid piston rod (STVD series) can be used as a locking cylinder
• Horizontal stop cylinder with shock absorber (STHSR series) reliably stops heavy conveyed loads at high transport speeds. Well-suited for buffer areas
• Horizontal stop cylinder with shock absorber (STHSR series) for buffer areas
• Lightweight aluminium diecast body
Applications:
• Moving and positioning of process parts
• Material feeding systems
• Directional control of conveyor paths
General Technical Data:
• International Standards : N/A
• Bore Sizes : Ø50
• Stroke Length : 30 and 50mm
• Versions : Double acting / Single acting spring return
• Cushioning : Rubber buffer or hydraulic industrial shock absorber
• Installation : Directly mounted
• Mounting Position : Any
Operating and Environmental Data:
• Operating Medium : For best possible service life and trouble-free operation dry, filtered compressed air to ISO 8573-1:2010 quality class 3.4.3 should be used. This specifies a dew point of +3°C for indoor operation (a lower dew point should be selected for minus temperature operation and we recommend the use of an inline dryer) and is in line with the air quality from most standard compressors with a standard filter.
• Operating Pressure : 2 to 10 Bar
• Operating Temperature : Standard temperature 0°C to +65°C
• Pre-lubricated : Further lubrication is normally not necessary. If additional lubrication is introduced it must be continued.
• Corrosion Resistance : Resistant to corrosion
Material Specification:
• End Cover : Die cast aluminium
• Cylinder Barrel : Die cast aluminium
