SC²25 to SC²190 Piston Tube Design for Maximum Energy Absorption

Product Description

Self-Compensating, Piston Tube Technology
Energy capacity 10 Nm/Cycle to 31 Nm/Cycle
Stroke 8 mm to 12 mm
Soft damping, but enormous capacity: The range of ‚soft contact‘ absorbers SC²25 to 190 extends from thread size M10 to M14 and covers effective weight ranges of 1 kg to 1,550 kg. All models are characterized by high energy absorption and they also unite the piston tube technology with the diaphragm seal perfected by ACE. This enables direct installation as end position damping in pneumatic cylinders at 5 to 7 bar or applications where deceleration needs to take place close to the pivot point.
They are maintenance-free, have an integrated positive stop, and are mountable in any position. The option of a side load adapter allows impact angles of up to 25°.
Thanks to their robust design and their durability, these miniature shock absorbers can be used for a wide range of applications. Designers mainly use them for pick and place systems, pneumatic rotary modules, and in automation applications.

SC²300 to SC²650 Piston Tube Design for Maximum Energy Absorption

Product Description

Self-Compensating, Piston Tube Technology
Energy capacity 73 Nm/Cycle to 210 Nm/Cycle
Stroke 15 mm to 23 mm
Added safety with accumulator technology:
The larger‚ soft contact‘ models from the SC²300 to 650 are available with up to three times the energy absorption compared to similar sizes of standard shock absorbers SC190 to 925, due to the ACE piston tube speciality. Furthermore, the membrane accumulator serves as a compensation element for the oil displaced in the shock absorber and replaces the standard use of absorber materials. This increases process safety even further.
The absorbers, which are perfect for rotary modules for example, are available in progressively stepped effective weight ranges with an integrated positive stop. They are maintenance-free and ready for direct installation. The side load adapter option allows impact angles of up to 25°.
These miniature shock absorbers offer high performance levels with a long service life and are particularly popular for handling, mounting very close to pivots and automation tasks.

Technical Data

• Energy capacity: 73 Nm/Cycle to 210 Nm/Cycle
• Impact velocity range: 0.09 m/s to 3.66 m/s. Other speeds on request.
• Operating temperature range: 0 °C to 66 °C Mounting: in any position
• Positive stop: Integrated
• Material: Outer body: steel corrosion-resistant coating; Piston rod: hardened stainless steel; Accessories: hardened steel and corrosion-resistant coating
• Damping medium: oil, temperature stable
• Application field: turntables, swivel units, robot arms, linear slides, pneumatic cylinders, handling modules, machines and plants, finishing and processing centers, tool machines
• Note: If precise end position datum is required consider use of the stop collar type AH.
• On request: Increased corrosion protection. Special finishes.

SC33 to SC45 Piston Tube Design for Maximum Energy Absorption

Product Description

Self-Compensating, Piston Tube Technology
Energy capacity 155 Nm/Cycle to 680 Nm/Cycle
Stroke 23.1 mm to 48.6 mm
True performers: The combination of the proven sealing technology from the MAGNUM range including membrane accumulator with the well-known piston tube technology from the SC² family makes the SC33 to 45 absorber models so strong and durable. The increase of the oil volume ensures the maximum effective weights. Short stroke lengths of 25 mm to 50 mm lead to shorter braking times in combination with a high energy absorption.
These dampers safely and reliably decelerate rotary movements without unwanted recoil effects. Assembly close to the pivot point is possible. The low impact speeds with this are managed with ease by ACE‘s generation of piston tubes.
These self-compensating industrial shock absorbers can be relied on in mechanical engineering. They are used in pivot units, rotary tables, robot arms or integrated else where in construction designs.

Technical Data

• Energy capacity: 155 Nm/Cycle to 680 Nm/Cycle
• Impact velocity range: 0.02 m/s to 0.46 m/s. Other speeds on request.
• Operating temperature range: -12 °C to +66 °C. Other temperatures on request.
• Mounting: In any position
• Positive stop: In any position
• Material: Outer body: Nitride hardened steel; Piston rod: Hard chrome plated steel; Rod end button: Hardened steel and corrosion-resistant coating; Accessories: Steel with black oxide finish or nitride hardened
• Damping medium: Low temperature hydraulic oil
• Application field: Turntables, Swivel units, Robot arms, Linear slides, Pneumatic cylinders, Handling modules, Machines and plants, Finishing and processing centres
• Note: A noise reduction of 3 to 7 dB is possible when using the special impact button (PP).
• Safety instructions: External materials in the surrounding area can attack the seal components and lead to a shorter service life. Please contact ACE for appropriate solution sugges- tions. Do not paint the shock absorbers due to heat emission.
• On request: Special oils, mounting inside air cylinders or other special options are available on request.
