Mechanical Power Transmission S-Flex Couplings Imperial Sized T Type Hubs 21 Front Mount Taper Dimensions Inches F Type Coupling F Type Flange ® T Type Flanges For Use With Taper-Lock Bushings TF Type Flanges » 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 any style of sleeve as pictured on page SF-5 TR Type Flanges. » TR flanges are similar to the TF style, but allow for the Taper Lock Bushing to be mounted and removed from the reverse or serration side of the flange. » The limited torque ratings of the Taper Lock Bushings allow TR flanges to only be used with EPDM or Neoprene sleeves. » Different bushing sizes are used, so they have different maximum bores than the TF flanges. » Sizes 6 through 16 are available Taper-Lock Bushings. Note: 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 andmetric bores. Outside of the U.S.A. it is most common to see B.S.W., especially on metric bores. www.jbj.co.uk/s-flex-couplings.html #DriveLineHarmony UNC Flange UPC Number BSW Flange UPC Number ID1 - ID2 Max Bore ID1 - ID2 Max Bore OAL G R OD L FL P HD Bush Flange Bush Size Screw Size Weight Required* in in in in in in in in in in lbs 6TF 62265 62263 4.00 0.88 1.25 1.09 4.00 1.56 0.78 0.78 2.81 ³⁄ - 16 1.8 1215/1210 7TF 62269 62267 3.94 1.00 1.25 1.31 4.62 1.84 0.78 0.69 2.81 ³⁄ - 16 2.6 1215/1210 8TF 62273 62271 5.00 1.13 1.62 1.50 5.45 1.94 0.91 1.03 3.25 ³⁄ - 16 3.7 1615/1610 9TF 62277 62275 6.00 1.44 2.00 1.75 6.35 2.28 1.09 1.25 4.13 ⁷⁄ - 14 6.2 2012 10TF 62281 62279 7.00 1.63 2.50 2.00 7.50 2.69 1.22 1.47 4.75 ¹⁄ - 13 9.8 2517 11TF 62285 62283 8.00 1.88 2.50 2.38 8.63 3.06 1.50 1.56 5.63 ¹⁄ - 13 16.4 2517 12TF 62289 62287 8.25 2.31 3.00 2.69 10.00 4.00 1.69 1.28 5.75 ⁵⁄ - 11 26.6 3030 13TF 62293 62294 9.25 2.69 3.00 3.06 11.75 4.38 1.97 1.31 6.75 ⁵⁄ - 11 45.0 3030 14TF 62297 62295 9.88 3.25 3.94 3.50 13.88 4.50 2.25 1.06 7.50 ¹⁄ - 13 69.0 3535 16TF 62301 62299 14.50 4.75 4.44 4.25 18.88 6.00 2.75 2.00 8.00 ⁵⁄ - 11 125.0 4040 OAL G R OD L FL P HD Bush Flange Bush Size Screw Size Weight Required* in in in in in in in in in in lbs 6TR 62266 62264 4.00 0.88 1.00 1.09 4.00 1.56 0.78 0.78 2.81 ¹⁄ - 20 1.8 1008 7TR 62270 62268 3.94 1.00 1.12 1.31 4.62 1.84 0.78 0.69 2.81 ¹⁄ - 20 2.6 1108 8TR 62274 62272 5.00 1.13 1.25 1.50 5.45 1.94 0.91 1.03 3.25 ³⁄ - 16 3.7 1215/1210 9TR 62278 62276 6.00 1.44 1.62 1.75 6.35 2.28 1.09 1.25 4.13 ³⁄ - 16 6.2 1615/1210 10TR 62282 62280 7.00 1.63 1.62 2.00 7.50 2.69 1.22 1.47 4.75 ³⁄ - 16 9.8 1615/1210 11TR 62286 62284 8.00 1.88 2.50 2.38 8.63 3.06 1.50 1.56 5.63 ¹⁄ - 13 16.4 2525 12TR 62290 62288 8.25 2.31 2.50 2.69 10.00 4.00 1.69 1.28 5.75 ¹⁄ - 13 26.6 2517 13TR 62294 62292 9.25 2.69 3.00 3.06 11.75 4.38 1.97 1.31 6.75 ⁵⁄ - 11 45.0 3030 14TR 62298 62296 9.88 3.25 3.00 3.50 13.88 4.50 2.25 1.06 7.50 ⁵⁄ - 11 69.0 3030 16TR 62302 62300 14.50 4.75 4.44 4.25 18.88 6.00 2.75 2.00 8.00 ⁵⁄ - 11 125.0 4040 Rear Mount Taper Dimensions Inches UNC Flange UPC Number BSW Flange UPC Number » The industry standard taper lock bushing is a split design allowing a compression fit of the flange to the shaft without set screws. » The simple design makes the installation and removal easy while the 8° taper grips tight and provides excellent concentricity. » Reduced l eve l of i nventory achieved due to the many other components that use Taper Lock Bushings such as sheaves, sprockets and pulleys. All data above refers to both standard UNC and British Standard Whitworth B.S.W. threads. Flanges are not supplied with screws. *indicates that the use of a 1210 or 1610 bushing reduces the reserve factor between bushing torque rating and that of the coupling.
