Round cylinder ZD 160 bar

Product catalog summary

Overview: The document provides technical specifications and details for the Double Acting Cylinder ZD, designed for hydraulic applications with a nominal pressure of 160 bar and a proof pressure of 240 bar. It includes various configurations and mounting options to suit different operational needs.

Specifications:

Pressure: Nominal pressure is 160 bar, with a proof pressure of 240 bar.
Dimensions: Piston diameters range from 20 to 125 mm, and piston rod diameters range from 14 to 90 mm. Stroke lengths can reach up to 3,000 mm.
Fluid and Temperature: Compatible with mineral oils DIN 51524 (HL, HPL), with a fluid temperature range of -20 to +80°C and a viscosity range of 2.8 to 380 mm²/s.
Velocity and Tolerance: Stroke velocity is 0.5 m/s, with stroke length tolerances of +1.5 mm for piston diameters up to 63 mm and +2 mm for diameters from 80 mm.

Configurations:

Cylinder Type: ZD for double acting, ZDGL for double rod.
Piston Rod End: Options for internal (I) or external (A) threads.
Mounting Types: Includes tapped hole (X), self-aligning clevis (G), round flange (KV, KH), and trunnion mounting (ZV, ZH, ZR).
End Position Cushioning: Adjustable options available for front (DH), rear (DV), both ends (DB), or none.
Seal and Rod Versions: Standard (A), servo quality (B, C), with rod options including hard chromium-plated (C), hardened (H), nickel plated (N), and inductive melting (S).

Performance Data:

Push and Pull Forces: Detailed in kN for various piston and rod diameters.
Piston and Annulus Areas: Provided in cm² for different sizes.

Mounting and Installation:

Installation Position: Arbitrary, allowing flexibility in setup.
Mounting Types: Includes self-aligning clevis, round flange, and trunnion mounting, with specific dimensions and configurations detailed.

Additional Information:

Buckling Load Calculation: Guidelines provided for calculating permissible buckling load based on cylinder length and mounting type.
Spare Parts: Includes details on components like the head, rear end, barrel, piston rod, piston, slotted round nut, and seal kit.

Ermittlung der zulässigen Knickbelastung FK zul Kolbenstangen mit einer verhältnismäßig großen Baulänge gegenüber ihrem Durchmesser müssen auf Knickung berechnet werden. Wird die zulässige Knickbelastung überschritten, besteht die Gefahr, dass die Kolbenstange sich plastisch verformt. Die Berechnung der Knickbelastung basiert auf der Länge des Zylinders im ausgefahrenen Zustand in Abhängigkeit zur jeweiligen Befestigungsart im senkrechten Einbaufall. dK = Kolbenstangendurchmesser [mm] S = Sicherheitsfaktor in der Regel 2- 5 [üblicherweise Faktor 3] SK = freie Knicklänge, sie setzt sich aus dem...
