KAron V Wear Strip

Kamatics KAron Wear StripKamatics KAron V Light Duty & Medium Duty Wear Strips are designed for surfaces that are subjected to light and medium duty rubbing pressure, or as a fretting resistant barrier. The mating sliding material should be smooth, hard, and a corrosion resistant surface. For optimal KAron V wear strip performance, the sliding component should have a minimum surface roughness of 16 RMS (0.4 μm), and be in full contact with the wear strip to avoid line or point loads.

KAron V wear strips are available in two standard thickness, and can be cut in various strips washers, and custom shapes. The material grades:

KAron V Wear Strip Grade Product Description Nominal Thickness
100 Light Duty Wear Strip 0.018” (0.46mm)
200 Medium Duty Wear Strip 0.036” (0.91mm)

 

Physical properties of KAron V wear strips are largely dependent upon the adhesive bond integrity, the substrate material, and surface preparation of the substrate. The below values are based on the wear strip only:

Coefficient of Friction 0.04 - 0.08  
Compressive Strength 30,000 psi 207 MPa
Max Dynamic Load 10,000 psi 69 MPa
Max Operation Temperature 250°F 120°C
Wear Rate 0.5x10-6 inch/ft of travel 41.6x10-6 mm/meter
Hardness 85 – 90 Rockwell M  

 

KAron V Wear Strips come with a woven nylon peel-ply on the back of the fiberglass to protect the bonding surface from dirt and debris. When the pull tab (T) option is called out in the part number, a 3/8" (9.5mm) long break away tab will be provided for easy removal of the peel ply backing. With the peel-ply removed and the back surface exposed, the wear strip is prepared for bonding onto a suitable surface. A room-temperature curing structural epoxy adhesive (2) is recommended for bonding KAron V Wear Strip material.

Suggested structural adhesives include Hysol EA9460, Hysol EA9309, Hysol EA9394 (Loctite), Scotchweld 460 (3M Co.), Araldite 2011 (Vantico).

For standard cut strip dimension parts, Kamatics uses the below part numbering system.

KAron V Wear Strip Unit of Measure Wear Strip Grade   Width   Length

 

Unit of Measure = BLANK for English units
M for metric units
Wear Strip Grade = See Wear Strip Grade table above
Width = English units: width in 1/8" increments up to 12", example 024 = 3" wide
Metric units: width in 5mm increments up to 300mm, example 020 = 100mm wide
Length = English units: length in 1/4" increments up to 48", example 096 = 24" long
Metric units: length in 10mm increments up to 1200mm, example 050 = 500mm long

 

Kamatics KAron V wear strips are not affected by the following chemicals and contaminants: Phosphate Ester Hydraulic Fluid (Skydrol), MIL-T-5624 Turbine Fuel Grade JP-4, MIL-PRF-7808 Lubricating Oil, MIL-PRF-5606 Hydraulic Oil, MIL-A-8243 Anti-Icing Fluid, MIL-H-83282 Hydraulic Fluid, Fresh Water, Salt Water.

The wear strip materials performed very well in independent laboratory testing. The methods used for the testing were MIL-STD-810F Environmental Engineering Considerations and Telecordia General Requirements. When subjected to tests for High and Low Temperatures, Solar Radiation, Blowing Rain, Fungus, Humidity, Salt Fog, Blowing Dust, Functional Shock, and Ozone Resistance, the Kamatics wear strip material test samples showed no signs of damage or degradation.
