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.
