最大壓力：
這系列設計的所有安裝類型均符合標準的160bar動態連續壓力。
在一定條件下，較高的壓力，是被允許的。為了證實這一點，我們需要建立一個在此基礎上的技術數據表、符合ISO 9001標準的應用說明。以案件為例再生電路或meter-out throttle，必須考慮壓力加劇。使用時，聯同meter-out throttle，動力在液壓缸內的壓力不得超過 420bar。
最小壓力：
為了確保液壓缸的操作正確，需根據不同的應用，使用正確的最低壓力。在無負荷情況下，單桿缸，建議最低壓力為 10bar。若是壓力較低或雙桿缸的案件，請與我們聯繫。
安裝氣缸：
當液壓缸安裝或活塞桿端鎖入機器或鎖入一個自我調整U-形鉤時，只能在液壓缸不被加壓的情況下。
活塞桿：
活塞桿材料，是以硬鉻板，高彈性的硬化鋼為標準。這確保了對機械的高抗衝擊性和最佳的使用壽命。把末端螺紋的直徑減小，從而達到保護的效果。標準 DIN 24554和NF / ISO 6020/2僅提供一種螺紋規格在每單位活塞桿直徑中。這確保了在標準機構內，有充分的傳輸動力。ISO 6020/2另外又提供了第二個，單位活塞直徑最大活塞桿的更大螺紋。外螺紋以及內螺紋不同於依據 DIN 24554和NF/ISO 6020/2，延長活塞桿或是螺紋端都是可行的。不論如何，當螺紋小於規定的使用標準時、所允許的最大壓力限制，都必須被標記出來；當使用更大的螺紋時，安裝選項的限制亦須加入考慮。
油封版本：
標準而言，有3個油封的版本可供選擇：“S”型（標準），“L”型（低摩擦）和“V” 型（高溫應用）。有關油封使用、各式溫度和速度範圍的資訊。油封裝置空間符合ISO 5597的“S”型活塞桿油封，ISO 7425-1所有活塞油封件和ISO 6195 - C的所有活塞桿起桿。油封 “S” 型規定的抗水解起桿，可在更高的速度下運作，如果壓力低於 100bar，頻率為不到3赫茲。長衝程液壓缸最好裝有油封“S” 型。
活塞桿引導軸襯：
由40毫米的活塞直徑，活塞桿引導軸襯是為螺纹插梢而設計的，由等級GGG - 50灰鑄鐵製成，符合DIN 1693。為確保安裝的簡便而允許開放式的設計，只較小的直徑是被鎖住的。而有油封安裝的引導軸襯可作為備用零件的目的。
活塞：
把Version with integrated 阻尼nose，鎖在活塞桿上，膠合並透過grub螺絲以穩固。油封的安裝空間，不管版本“S” 型，“L”型或“V” 型，按ISO 7425-1都是統一的，也就是說無需活塞的變化可就以更換油封。
缸體、前蓋、後蓋間之油封：
油封安裝空間的附加設計-把barrel集中在兩邊，以確保最佳的油封。尤其是長衝程液壓缸。
衝程公差：
根據 ISO 8131，衝程達1250毫米，衝程公差 0 / +2毫米是被允許的;若需要更長的衝程，請與我們聯繫。公差 ± 0.3毫米，不見得合適；更小的公差，對於尖桿缸是沒有用的。
建議的最大衝程：
衝程建議放置於目錄中，以確保所有在最高壓力為160bar的操作條件下能正常運作。潰曲附載必須在所有的情況下被核實。只有在較低壓力或拉力負載的情況下，才可能用到較長的衝程。
最小衝程：
在安裝類型“MT4”可以觀察到，最小衝程與耳軸的寬度有關。使用終端位置的緩衝，也可以同時觀察到最小衝程。在案例中，衝程長度小於緩衝的長度，我們推薦使用一個沒有緩衝終端位置的液壓缸。而這可能會需要阻止管的膨脹和尖桿的支撐。
管道連接：
液壓缸可用在BSP螺紋並可將其擴大至符合ISO 8138及公制ISO螺紋DIN /ISO 6149-1。
底漆塗層：
液壓缸是底漆單塗層，最厚 80微米，為標準。其他顏色有待詢問。
ISO 6020/2 cylinders
Features:
• Installation dimensions to ISO 6020/2, DIN 24554 and NF/ISO 6020/2
• 13 mounting types
• Piston φ 25 to 200 mm
• Piston rod φ12 to 140 mm
• Stroke lengths up to 2700 mm
• Integrated guide bushing for simple and easy maintenance
• Self-adjusting or adjustable end position cushioning optional
• Patented safety bleeding system for simple and reliable bleeding
• Ease of installation due to freely selectable position of pipe connections on head and cap
Maximum pressure:
These series are designed in accordance with standards for a dynamic continuous pressure of 160 bar for all mounting types.
Under certain conditions, a higher pressure may be permitted. To confirm this, we require a detailed application description on the basis of a technical data sheet in line with the ISO 9001 quality standard. In the case of a regenerative circuit or a meter-out throttle, pressure intensification must be taken into account. When used in conjunction with a meter-out throttle, the dynamic pressure in the cylinder must not exceed 420 bar.
Minimum pressure:
Depending on the application, a certain minimum pressure is required to ensure correct operation of the cylinder. Under no-load condition, a minimum pressure of 10 bar is recommended for single rod cylinders. In the case of lower pressures or double rod cylinders, please consult us.
Installation of cylinder:
The cylinder may only be installed or the piston rod end screwed into the machine part or into a self-aligning clevis while the cylinder is de-pressurized.
Piston rod:
The piston rod material used as a standard is hard chromium-plated, hardened steel with a high elasticity value. This ensures high resistance against mechanical impacts and an optimum service life. The end of the thread is reduced in its diameter and hence protected. Standards DIN 24554 and NF/ISO 6020/2 provide only one thread size per piston rod diameter. This ensures the full transmission of dynamic forces within the framework of the standard. ISO 6020/2 additionally provides a second, larger thread for the largest piston rod per piston diameter. Male threads differing from DIN 24554 and NF/ISO 6020/2 as well as female threads, extended piston rods or thread ends are available. However, it must be noted that when a thread smaller than that provided in the standard is used, the permissible maximum pressure is restricted and, with larger threads, the limits of mounting options must be taken into account.
Seal versions:
As a standard, 3 seal versions are available: “S” (standard), “L“ (low friction) and “V“ (high-temperature applications). For information about the use of seals for various temperature and velocity ranges. The seal installation spaces comply with ISO 5597 for “S“ piston rod seals, ISO 7425-1 for all piston seals and ISO 6195-C for all piston rod wipers. Seal version “S“ is provided with a hydrolysis-resistant wiper and can be operated at higher velocities, if the pressure is lower than 100 bar and the frequency is less than 3 Hz. Long-stroke cylinders are preferably fitted with seal version “S“.
Piston rod guide bushing:
From piston diameters of 40 mm on, the piston rod guide bush is made of grey cast iron grade GGG-50 to DIN 1693 and designed as screw-in cartridge. Smaller diameters are of screwed, open design to ensure ease of installation. Guide bushes with seals installed are available for spare parts purposes.
Pistons:
Version with integrated damping nose, which is screwed onto the piston rod, glued on and secured mechanically by means of a grub screw. The seal installation spaces are identical for seal versions “S”, “L” and “V” in accordance with ISO 7425-1, that is, the seals can be replaced without requiring a piston change.
Seals between barrel, head and cap:
The enclosed design of seal installation spaces with centering of the barrel to both sides of the seal ensures optimum sealing, especially for cylinders with long strokes.
Stroke tolerances:
According to ISO 8131, for strokes up to 1250 mm a stroke tolerance of 0/+2 mm is permitted; in the case of longer strokes, please consult us. A tolerance of ±0.3 mm is optionally possible; smaller tolerances are not useful for tie rod cylinders.
Recommended maximum strokes:
The strokes recommended in catalogue ensure proper operation under all operating conditions at a maximum pressure of 160 bar. The buckling load must be verified in all cases. At lower pressures or pulling loads only, longer strokes are possible on request.
Minimum strokes:
For mounting type “MT4“ observe the minimum stroke due to the trunnion width. When using end position cushioning, also observe the minimum stroke. In the case of stroke lengths shorter than the cushioning length, we recommend the use of a cylinder without end position cushioning. Stop tube extensions and tie rod supports are possible on request.
Pipe connections:
Cylinders are available with BSP thread and enlarged BSP thread to ISO 8138 and with metric ISO threads to DIN/ISO 6149-1.
Primer coating:
As a standard, hydraulic cylinders are primered with one coat of max. 80 μm. Other colors on enquiry.
