Piston rings - Import export

Compressor piston ring set, 4 inch diameter.

When to use piston rings? When piston rings with excellent wear properties are required When simple assembly is of great importance When high edge loads occur When tailor-made solutions based on iglidur® materials are required When not to use piston rings? When the piston rings should seal simultaneously When different diameters should be covered by one part Before: with piston rings: Why complicate things when it can be done differently? Replace elaborately stamped PTFE tapes with a single clip-on guide ring, such as in lifting elements, control valves and fittings. We offer iglidur® piston rings made of freely selectable materials for a wide range of applications. Special properties Easy to assemble Low-priced More wear-resistant than PTFE-bonds Higher load capacity Defined dimensions different materials per ex. iglidur® J, J350… iglidur® piston rings - application examples When to use piston rings?

ALFAMAK is one of Turkey's leading gas spring manufacturers. Established in 2003, our company has been operating in the industry for 19 years and has gained a reputation for success. Gas spring is a new technology which comes instead of standard steel or polyurethane springs. A gas spring has a container of compressed Nitrogen gas with Piston Rod , Bush, Rod Rings, Valve etc. The Gas Springs are used in Cold Stamping industry to form, cut and fix the sheet metal inside the die. Many auxiliary materials are used for different purposes in the gas spring. Rod wiper, rod guide and rod seal are used on the inner surface of the bush. The purpose of the rod wiper is to prevent the oil and chips in the die from entering the gas spring. The rod guide is used to carry the load in case of axial force on the rod during use. The most important auxiliary material for sealing is rod/piston seal. It directly affects the performance of the product by keeping the gas in the gas spring.

A double-acting O-Ring energized piston seal which includes a polyurethane seal ring - suitable for dynamic applications. The Zurcon® Wynseal is a tear and abrasion resistant seal with an especially high sealing effect, aided by the special design of the seal edge profile.

A single-acting O-Ring energized piston seal for dynamic applications, the Turcon® Stepseal® 2K provides excellent static and dynamic sealing results. This advanced seal is stick-slip free, suits a wide range of application temperatures and demonstrates excellent abrasion and extrusion resistance. Optimum sealing characteristics are achieved by installing in a tandem arrangement.

Turcon® Glyd Ring® T is a double-acting O-Ring energized piston seal for dynamic applications, available in a range of materials (e.g. Turcon® and Zurcon®). Fully interchangeable with the earlier Glyd Ring® T, it provides very good static leak tightness and good resistance to extrusion, also demonstrating excellent friction characteristics with no stick-slip, minimal break-out force and high wear resistance
