  • KF Guide Strip MERKEL Piston Guide Band, PTFE/Bronze

    This is a five-piece compact piston seal set made up of a profile ring, two backup rings and two angled bushes. The piston L43 is fitted to seal pressure on both sides of the piston, and the angled bushes act as guide elements.

    Technical Data

    Please contact Industrial Seal Inc.

    Applications

    • Injection molding machines
    • Control and regulating apparatus
    • Handling equipment
    • Rolling mill
    • Steel
  • SF Guide Strip MERKEL Rod Guide Band, PTFE/Bronze

    Merkel Rod Guide Band material is designed for hydraulic and pneumatic equipment. It's unique design prevents equipment seizures which can arise with other forms of guidance materials. Merkel Guide Bands offer extremely low friction and break away forces. This material is also resistant to all hydraulic fluids, and is suitable for temperatures up to 250F.

    7.5 N/mm2/ 1087 PSI at 80C/176F
    5 N/mm2/ 725 PSI at 120C/248F
    (permitted specific surface pressing*)
    PTFE B500
    (PTFE Bronze compound)

    Applications

    • Injection molding machines
    • Control and regulating apparatus
    • Handling equipment
    • Rolling mill
    • Steel

    Non-metallic rod-guide strip, available selection of ready-to-fit or cut-to-size products.

    • Material pairing metal/plastic prevents "seizure"
    • Load-bearing capacity limited (material)
    • Low friction, free of stick-slip
    • Dry running characteristics with poor lubrication
    • Good damping at radial vibration
    • Bedding-in of foreign bodies possible
    • Chamfered profile edges prevent pressing of edge in the corner radi of the housing groove

    Guide tapes for piston rods (SF) of medium to heavy duty cylinders in hydraulic and pneumatic applications, offering the following advantages:

    • Replace costly metallic guides
    • Ease of installation
    • Good damping properties taking up radial vibration
    • Good emergency running properties in case of lubrication deficiency
    • No contact between metal parts

    Guide tapes SF are available as rolls as well as cut-to-length tape.

  • KF Guide Ring MERKEL Piston Guide Band, Phenolic Resin

    Merkel Phenolic Resin Bonded Fabric Guide Bands are designed to be extremely robust and carry very heavy side loads up to 270 M/mm. These guide bands also offer very good thermal stability & low water absorption. The Cotton fabric is typically used in diameters < 300mm/ 12.00", and Polyester is more commonly used for larger sizes and may be supplied in strip form. Merkel Resin Bonded Fabric Guide Bands are supplied with chamfers on all sides to allow for better fit and service life.
