Sure-flex bts coupling 7 s epdm rubber 3/4" - 1" bore
SURE-FLEX BTS COUPLING 7 S EPDM RUBBER 3/4" - 1" BORE
This listing is for 1 coupling which appears possibly to be new old stock. Although it has a lot of cosmetic surface wear, including a ding or two from dropping and old paint, as seen, it shows no noticeable signs of actual use and rubber has no cracking. Constructed of three seperate pieces: one EPDM rubber sleeve and two flanges. One flange has a bore of 3/4" with 3/16" keyway and one flange has a bore of 1" with 1/4" keyway. + .0005 to + .0015 bore tolerances. Rated at 1.2HP @ 100rpm, 13HP @ 1160rpm, 20HP @ 1750rpm, 40HP @ 3500rpm. 725 in. lbs. torque. 2769 in.lbs./rad stiffness. 5250 max rpm. Entire coupling assembly measures approx 4-5/8" overall diameter and 3.950" long. Space between flanges is approx 1". Made by T.B. Wood's. Sure-Flex type S BTS coupling No. 7. Don't miss your chance to own it now!
TB Wood's Sure-Flex couplings use a rubber (EPDM), neoprene, or Hytrel sleeve and have exceptional torsional flexibility. Their 4-way flexing action absorbs virtually all types of shock, misalignment, and end float. With Sure-Flex couplings, the need for lubrication and maintenance is eliminated. As a result, these couplings provide clean, dependable, and quiet performance for a variety of applications. Lubrication-free design makes these couplings quiet and reliable. Flexible sleeves available in EPDM, Neoprene, and Hytrel. Fast and easy installation without bolts, gaskets, covers or seals. Uniquely designed teeth and lateral flexibility accept both parallel and angular misalignment without wear. Four-way flexing action absorbs extreme torsional shock and vibration.
Note: Spacing between shafts should be greater than 1/8 in. and less than the length of entire coupling assembly minus .85 times the sum of the two bore diameters.
See pictures for more details and information of condition and please make sure that this is what you need before purchasing, as it is non-returnable. Thank you.
CONDITIONS AND NOS: Sometimes NOS (NEW OLD STOCK) items can be very old and although they are new can have slight imperfections in them. This may because of the way they were made years ago or may have slight imperfections, bruises, scuffs or minor dings from being moved around the shelving over the years with other items bumping into them. We do our best to describe these imperfections (if any) in our listings when ever possible worth noting.
