MACMA

Macma is a trade name for a range of polyurethane parts made by the Gapi Group.

The material used is either an injection or pour polyurethane in a distinctive orange colour.

Parts are manufactured in a metric range of styles, including MAD - a U style part, CSC - a solid piston / rod seal style, ASR wiper seal, to suit the application.

We have the capability of producing up to 750mm diameter seals.

MAD

POLYURETHANE U SEALS

The Polyurethane U Seals of the series MAD-UMAD-M are made in Polyurethane 95 Shore A and are used as a dynamic seal on rod and piston cylinders.

Thanks to the characteristics and high hardness of the material these seals ensure a remarkable resistance to abrasion and extrusion. The shape and elasticity of the lips, when combined with a good compression set of the material, allow the seals to give high performance and long duration.

CSC

REINFORCED POLYURETHANE PISTON/ROD SEALS

The CSC series of Seals are made of polyurethane 90 Shore A and are suitable for the dynamic seal on piston rods of hydraulic cylinders.

They can be used as a dynamic seal on pistons, but only for single effecting.

Thanks to the characteristics and high hardness of the material, these seals ensure a remarkable resistance to abrasion and extrusion. Their rugged construction and good compression set of the material, help to ensure high performance and a long life, promote the seal even at low pressures.

If it is necessary to use them for higher pressures we can provide with hardness 95 Shore A.

ASR

POLYURETHANE SINGLE WIPER SEALS

The Wiper Seals of the ASR-P series are made of a polyurethane 90 Shore A.

Thanks to the excellent abrasion resistance of the material used, these wipers are long lasting even in severe operating conditions.

RAD

POLYURETHANE DOUBLE LIP WIPER SEALS

Wiper Seals of the RAD series are used to prevent the contamination of impurities within hydraulic apparatuses, thus protecting both the seals that the metal parts that otherwise could be damaged.

Made from a polyurethane 95 shore A gives better abrasion resistance compared to the NBR, which ensures a longer life and can be used in more severe operating conditions

For special uses that require non standard sized seals they can be used in conjunction with the MAD UMAD M series.
