Rollon Slideway Material

ROLLON SLIDEWAY is a high performance engineering thermoplastic material consisting of PTFE and sintered bronze along with special wear resistant additives.

It is a self-lubricating wear resistant material suitable for operating temperatures upto
260 ° C.

It is used on machine tool transfer lines or machine tool guideways or any linear movement applications, to avoid metal to metal sliding contact where reduced friction & wear resistance are critical design considerations.

Applications

Rollon Slideway Material Applications

Why use ROLLON Slideway?

Due to the specific properties of the bearing material, the use of ROLLON SLIDEWAY gives the following advantages over other metallic or non-metallic linear bearing systems:

  • Low friction without stick-slip, a requirement for positional accuracy at differenct velocities specially at low speed.
  • Excellent vibration damping characteristic in spite of low co-efficient of friction
  • High wear resistance
  • Machine tools work more accurately for longer periods of time and service intervals are extended.
  • Good chemical resistance to coolants and lubricants.
  • Excellent mechanical properties and dimensional stability.
  • Advantage of embedding foreign particles.
  • It can run dry without damaging the mating slide.
  • High positional accuracy and repeatability.
  • High performance over many years.
  • No swelling of the bearing material.
  • Low product cost.
  • Simple and easy installation.

Manufacturing & Testing Facilities

Manufacturing of ROLLON SLIDEWAY established from technical know-how and support received from BUSAK + SHAMBAN USA / GERMANY over several years.

Skiving

: Billets are skived to the required thickness in the state of the art, CNC SKIVING MACHINE which ensures uniform & consistent thickness with very close tolerances.

Etching Plant

: In order to achieve perfect bonding of the skived material , the interface materials is chemically etched on one surface of the material. The chemical etching on one surface ensures perfect bonding. Rollon provides the Industry's highest quality etched surface for superior bonding characteristics.

Testing

: Rollon tests the skived tape of every billet for co-efficient of friction and wear, both in lubricated and dry conditions to ensure conformity and very high quality of ROLLON SLIDEWAY MATERIAL.

Tensile Strength

: We also have in our inspection lab, tensile testing machine enabling us to conduct necessary test every skived sheet. These tests are conducted as per ASTM D1457.

Slitting Machine

: Specialized equipment has been installed to cut different sizes of strips from ROLLON SLIDEWAY material as per customer's specific requirements.

Installation Procedure

  • Correct Surface Finish

    : Metal surface finish suitable for bonding with ROLLON SLIDEWAY should not be less than 1.0μM or greater than 3.2μM to ensure the maximum possible bond strength.
  • Cleaning the Metal Mating Surface

    : A thorough cleaning of the surface is vital to ensure proper bonding. The cleaning solution may be acetone or trichloroethylene or perchloroetylene. Use of any other degreasers, petrol and thinner is not recommended.
  • Cleaning of Rollon Slideway

    : The etched SLIDEWAY surface identified by dark colour must also be cleaned prior to bonding.
  • Preparation of Adhesives

    : For bonding of ROLLON SLIDEWAY the recommended resin / adhesive is HUNTSMAN araldite AW106 & hardener HV953U. This should be mixed at room temperature, the proportion shall be as per the manufacturers recommendations.
  • Bonding

    : A thin even layer of mixed adhesive should be applied to both bonding surfaces. The stroke of spreading the adhesive over the ROLLON SLIDEWAY should be in longitudinal direction, when spreading adhesive on the metal-brush in transverse direction. Total quantity of adhesive required for bonding is appx 200 Gms/SQ mtr
  • Final Machining

    : After complete cure of the adhesive bonded ROLLON SLIDEWAY can be finished by hand scraping, milling or grinding.
  • Machining Oil Grooves

    : ROLLON SLIDEWAY can be machined to incorporate oil or lubrication groove patterns. It is best to mill the oil grooves into the material to a depth of 50-70% of material thickness
  • Metal Mating Surface Finish

    : The mating surface should be finished to 0.4μM for best performance. The surface finish should not be less than 0.3μM or greater than 0.5 μM
  • To Assist in the proper bonding of ROLLON SLIDEWAY please ask for a sequenced instruction sheet.
