VRA STATIC SEAL

 

DESCRIPTION

The VRA Static Seal type has been conceived to protect joints, bearings, bronze bushes, flanges and all the mechanical parts in rotation or semi-rotation made in B0 material, presenting a low compression-set, it prevents the penetration of water, mud and other impurities. The wide range of diameters facilitates the constructor’s choice.

 

TECHNICAL DATA

Pressure: it is not a traditional seal, the working pressure is therefore the one resulting from keeping the grease within the system.

Temperature: from -35°C to + 90°C

Fluid: mineral oil and grease, non-aggressive gas etc

 

MATERIAL

Standard polyurethane at 90 Sh A. Compound reference: B0

 

ASSEMBLY

Just lubricate with mineral grease the metal parts where the seal is installed. Edges and flash have to be avoided, they would otherwise damage the sealing capacity.
