Product Introduction of HEISS Standard Cylinder Series SZ 250
Product Overview
A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
A: Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through
a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
A: Sure. Show us the drawing, we will quote for you soonest.
A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.

Ultra-High Thrust Output for Heavy-Duty Tasks
With a 250 bar pressure rating, SZ 250 generates roughly 2.5x the thrust of SZ 100 and 1.56x the thrust of SZ 160, eliminating the need for costly booster cylinders for most heavy clamping, mold locking and metal forming operations. The reinforced barrel and piston assembly withstand continuous high-pressure cyclic loads without deformation.
Full-Spectrum Mounting Compatibility (23 Standard Attachment Types)
The series covers all mainstream industrial installation forms: front square flange (112 type, matching the 3D drawing structure), rear flange, external thread embedded mounting, foot mounting, pivot pin mounting and tube clamping base mounting. Standardized hole dimensions eliminate custom machining for fixture base plates and shorten mechanical design lead timesdreiecklan...
Service-Optimized Modular Sealing System
The detachable gland design allows seal replacement without full cylinder disassembly. Universal standard seal grooves across all bore sizes reduce spare parts inventory and minimize production downtime during maintenance, fully aligned with HEISS’s unified spare parts management standard.
Outstanding Harsh Environment Adaptability
Standard conformal coated PCB and internal components resist dust, moisture and chemical vapors. Custom anti-corrosion internal assemblies support water-hydraulic systems, while ATEX certified variants satisfy safety requirements for powder, chemical and dust-explosion risk workshops
Full Compatibility with HEISS Complete Hydraulic Ecosystem
SZ 250 seamlessly integrates with HEISS PHU pneumatic-hydraulic booster units, DD multi-port rotary swivels, DIN 24554 SNZ norm clamping cylinders and SSZ swing clamp cylinders, forming complete hydraulic systems for rotary tables, heavy-duty multi-station CNC fixtures and die-casting automation lines.
