Request Information
  • Model TF flanges are made from the same high-strength cast iron as the S flanges, but are designed to accommodate the international standard Taper Lock bushing for easy installation and removal
  • TF Type flanges allow for mounting the bushing on the front (hub) side of the flange
  • TF flanges are available in sizes 6 through 16 and can be used with JE, JN, JES, JNS, E, N, H, and HS sleeve types.

  • Be sure to determine if the bushing being used has either UNC threads (60°) or British Standard Whitworth B.S.W. threads (55°). In the U.S.A. the UNC type is predominant for both inch and metric bores. Outside of the U.S.A. it is most common to see B.S.W., especially on metric bores.
  • All above data refers to both standard UNC and British Standard Whitworth B.S.W. threads. Flanges are not supplied with screws.
  • Use of a 1210 or 1610 bushing reduces the reserve factor between bushing torque rating and that of the coupling.
