With well over 35 years of product knowledge combined with a large stock of Sure-Flex Couplings and Sleeves provides a great basic shaft coupling solution. Mix that with knowledgeable staff who are always available, and you have a great combination. The basic coupling uses two cast hubs available pre-bored or pilot bored and a proven centre element produced from a elastic polymer, to compensate for arduous shaft misalignments. The proven product delivers reliable torque transmission whilst simultaneously dealing with shock and vibration.
The name TB Wood’s Sure-Flex® Product has long been associated with quality. TB Wood’sSure-Flex® couplings utilises a rubber (EPDM), Neoprene, or Hytrel sleeve between two cast hubs. The flexible element allows 4-way flexing action and absorbs virtually all types of shock, misalignment, and end float. The sleeves also exhibit exceptional torsional flexibility. The cast hubs can be supplied bored and keyed to suit motor shafts from 10mm to 140mm as standard . 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.
Sure-Flex® shaft couplings can be installed quickly and easily because there are no bolts, gaskets, covers or seals. Alignment can be checked with a straight edge placed across the outside of the precision machined flanges. No special tools are needed for installation, alignment or removal. With Sure-Flex couplings, the need for lubrication and maintenance is also eliminated. The uniquely designed connecting teeth allow lateral flexibility whilst accepting both parallel and angular misalignment without wear.As a result, these couplings provide clean, dependable, and quiet performance for a variety of applications.
If you require further technical information, please do not hesitate to contact our sales engineers who will be more than happy to help you with your selection.
Flexible sleeves for Sure-Flex couplings are available in four materials (EPDM, Neoprene, Hytrel and Urethane) and in three basic constructions. The various types are shown and described here.
J sleeves are molded EPDM rubber (E) or Neoprene (N). They are available in one-piece solid construction (JE, JN) or one-piece split construction (JES, JNS). These sleeves may be used in any Sure-Flex flange within a given size.
These sleeves are of two-piece design with a retaining ring. They are available in either EPDM (E) or Neoprene (N). They may be used with any flange within a given size. Sleeves are shown here assembled and disassembled.
H (Hytrel) and U (Urethane) sleeves designed for high-torque applications, transmit four times as much power as an equivalent EPDM or Neoprene sleeve. Available in one-piece solid construction (H or U) or two-piece split construction (HS), these can be used only with S, C, and SC flanges. They cannot be used with J or B flanges or as direct replacements for EPDM or Neoprene sleeves.
A full range of hubs and flanges are available to suit all the sleeves. All details can be found on the on line catalogue or call our knowledgeable sales team to help with your specification on 01386 421005.
