Isostatic TU® Thrust Washer Bearings
  • Standard stock products
  • Self-lubricating dry sliding bearing
  • A steel-backed composite material comprised of:
    • Low carbon steel backing for extremely high load capacity-.50 – 2.7mm thick
    • Sintered bronze offers optimal heat dispersion –.20 - .35 mm thickness and
    • PTFE – lead sliding surface creates a low friction coefficient and allows for a wide temperature range – thickness .2 mm
  • Can be used where many liquid lubricants fail; also performs well with lubrication
  • Ideal for heavy loads at moderate speeds or light loads at high speeds – max Pv 102,000, P-Load 36,250, V-SFM-1,900
  • Effective in temperature range of -328° F to +536° F
  • Standard tolerances vary by size. See items for specific tolerances
  • See TP® product line for a lead free, REACH and ROHS compliant alternative
