Physical character: PTFE guide stripe tape (GST) is a nano-polymer composites based on PTFE material, applying in all types of precision machine tools requiring high accuracy, CNC equipments and high-end guide bands products of processing centers. The guide bands contain rich solid lubricant particles which enables the bands have a excellent friction and wearing properties. By force of nano super fine recipe, uniform and dense material and strong wearing resistance, the soft bands are widely used in all types of common machine tools, textiles, printing, paper-manufacturing, food, chemical engineering, woodworker or manufacture and maintenance of other mechanical sliding guide especially precision machine tools etc.
Specifications:
material: 60%PTFE + 40%bronze
pressure:15Mpa@25°C, 12Mpa@80°C, 8Mpa@120°C
temperature: -60°C - +260°C
speed: 15m/s
high wearing resistance: normally 10times of cast iron guide, good accuracy maintenance
low friction: friction coefficient<0.04, only 1/3 of cast iron guide, reducing the driving-energy consumption
no creeping: moving steadily
good shock-absorbing ability: improving processing accuracy
good lubrication suitable for dry use (depending on the load)
good temperature resistance
compatible with most of the fluids in contact
easy assembly, low friction coefficient.
easy-to-do maintenance: as the hardness is much lower than metal, friction is mainly on the bands, we can just replace new bands. meanwhile, it prevents the middle-deboss of the machine tool body
