Simrit/CFW Hydraulic Piston Seals

The NA 150 mainly used as a replacement part requirement. For new designs we recommend the modern design series.

Applications

• Agricultural equipment
• Heavy mobile hydraulics
• Loading platforms
• Cranes
• General cylinders

The NA 150 is a single-acting piston seal, featuring asymmetrical sealing lips. This U-Cup is mainly used as a replacement part requirement.

The NA 300 U-Cup features an asymmetrical profile, outer lip set back and an inner diameter press fit. This single-acting piston seal has very good static and dynamic tightness. The NA 300 U-cup is recommended for standardized housings, according to ISO 5597.

Applications

• Agricultural equipment
• Heavy mobile hydraulics
• Loading platforms
• Cranes
• General cylinders

The Simko 300 is a two-piece compact seal consisting of one profile ring with a pronounced sealing edge and one contact pressure component for producing pre-tension. The double acting piston seal has low friction, smooth oparation movement even at low linear velocities, contact pressure component with rectangular cross-section, prevents twisting, standardised housings following ISO 7425 and low axial heights of housing.

Applications

• Earth moving equipment
• Fork lift trucks
• Agricultural equipment
• HGV loading cranes
• Injection molding machines
• Loading platforms
• General cylinders

Features

• Very good static and dynamic tightness
• Low friction, smooth operation movement even at low linear velocities
• Contact pressure component with rectangular cross-section, prevents twisting
• Standardized housing following ISO 7425
• Low axial heights of housing

Three-piece compact seal consisting of fabric-reinforced, elastomeric sealing body and two backup rings as a gap sealing component. Double-acting piston seal, preferably for replacement part requirement. For new designs we recommend modern design series.

Applications

• Agricultural
• Earth moving machines
• Loading platforms
• Mining
• Shears
• General cylinders
