Product Introduction of HEISS Standard Cylinder Series SZ 160

Product Overview

The SZ 160 is a heavy-duty round-body standard hydraulic cylinder series manufactured by HEISS GmbH, designed for a rated maximum operating pressure of 160 bar. Positioned between the entry-level SZ 100 (100 bar) and high-pressure SZ 250 (250 bar), it delivers stable medium-high thrust for general automation, fixture clamping, machine tool positioning and light forming applicationsheiss.de.

Featuring a robust, compact round steel structure with optimized internal guiding systems, SZ 160 boasts outstanding lateral load resistance and linear motion stability. All sealing grooves strictly comply with ISO 5597/1 and DIN ISO 7425/1 standards, ensuring fully interchangeable sealing components and convenient on-site maintenance. With 13 standard piston bore sizes and 23 universal mounting configurations, this series offers exceptional flexibility to match diverse mechanical layout requirements, and can be customized for harsh working environments including dust-explosion hazardous zones and water-glycol hydraulic media.

Q: What’s the MOQ of customized tie-rod cylinder?

A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.

Q:What’s the lead time of customized tie-rod cylinder?

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.

Q: Are you the manufacturer of hydrualic cylinder?

A: Sure, we are the manufacutuer and trading of hydraulic cylinder.

Q: What is the difference between double acting and single acting cylinders?own controlled by the pump or the valve or is it only one speed?

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.

Q: I have a drawing, could you customized cylinder as my drawing?

A: Sure. Show us the drawing, we will quote for you soonest.

Q: Could you make the cylinder which is not on the above data sheet?

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.

Higher Thrust Output vs SZ 100

With a 160 bar pressure rating, SZ 160 generates 60% higher clamping and pushing force than the 100 bar SZ 100 series, making it suitable for medium-load machining fixtures, aluminum alloy processing and moderate pressing tasks without upgrading to costly high-pressure 250 bar cylinders.

Ultra-Wide Mounting Compatibility

23 standardized mounting types cover all mainstream installation forms: front square flange (MF1 as shown in the 3D drawing), rear flange, threaded body, foot mounting, pivot mounting and tube clamping installation. This full compatibility eliminates custom machining for fixture base plates and shortens equipment design cycles.

Service-Friendly Modular Sealing Structure

The detachable gland and unified standard seal grooves allow rapid disassembly and seal replacement without full cylinder dismounting. Standardized spare seals reduce inventory costs and minimize production downtime for maintenance.

Excellent Anti-Interference & Harsh Environment Adaptability

PCB conformal coating is applied as standard, providing protection against dust, moisture and chemical vapors. Customized corrosion-resistant internal components are available for water-hydraulic systems, while ATEX explosion-proof variants satisfy chemical, powder and dust workshop safety standards.

Seamless Matching with Full HEISS Hydraulic Line

SZ 160 integrates perfectly with HEISS PHU booster cylinders, DD multi-port rotary swivels, DIN 24554 SNZ norm cylinders and SSZ swing clamp cylinders, forming a complete hydraulic system for rotary tables, multi-station CNC fixtures and automated production lines.
