It solves many maintenance problems in industries like pulp & paper, petrochemical, mining and steel. The hubs it is used with go up to a maximum bore of 4.00” (102mm).Ĭommon applications for the Lovejoy Jaw In-Shear Coupling include: electric motors to centrifugal pumps, fans, blowers, gear boxes, and plastic extruding machinery. Small pieces of metal inside the rubber will set off a metal detector, alerting you to the problem. Designed for use in food-processing applications, where a fraying spider could contaminate a batch, these couplings have a metal-detectable rubber spider. The Jaw In-Shear Spider is made from a tough Urethane formula which provides the best combination of durability, chemical resistance, temperature range, and torsional softness. Metal-Detectable Flexible Shaft Couplings. Existing applications using in-compression spiders can simply be retrofitted with the new In-Shear Spider if the features are beneficial. TOUGH AND TESTED STRONG AND FLEXIBLE STYLISH AND DURABLE ELEGANT AND COMFORTABLE PREMIUM AND CLASSY THE QUALITY THATS TESTED THE PERFORMANCE THATS.
Lovejoy’s In-Shear Spider is used with our industry-standard L-Type and C-Type Jaw Coupling hubs which provides another added convenience - no need to stock different hubs just for this new design of elastomer. It will not work its way loose and since there are no fasteners involved, the maintenance and removal of the Spider takes only a few minutes. The retaining ring which encloses the In-Shear Spider has six small pins which simply slide across a groove the perimeter of the Spider and twist-lock into place. This saves time and money in maintenance costs. The Jaw In-Shear Spider is radially removable, meaning that neither hub (or driver/driven equipment) has to be moved to make replacements of the Spider. The wider spider is then in a shear-plane. Material of Spider: EPDM, Hytrel (Basf) Bore Size of Hubs: Pilot Bore or Customized. Material of Hubs: Cast Iron, Powder Metallurgy of Sureflex.

Instead of the spider being compressed in between the interlocked jaws of each hub, our In-Shear coupling has the hubs drawn apart with the jaws aligned axially. ISO Approved High Quality S- Flex Coupling Size 5j. For applications which demand easy maintenance and the ability to accept both parallel and angular misalignment there is an extensive range of sizes, materials, and shaft mounting options to cover a wide range of “distance-between-shaft-end” spacing.The Jaw In-Shear Coupling is non-fail safe, and thus the coupling acts as a fuse to prevent equipment damage in the event of torque overloads. With a maximum torque load of 8.2kNm, the coupling can be used as an economical, reliable, highly flexible solution for pumps, fans, compressors, conveyors, mixers and other equipment. The only distinction is between the maximum surface temperature classes depending on the sleeve material EPDM and Hytrel are T4 ( <135C), while Neoprene and Urethane are T5 ( <100C). With Sure-flex couplings, the need for lubrication and maintenance is. Their 4-way flexing action absorbs virtually all types of shock, misalignment, and end float. The ATEX certificate covers all product designs within the range. TB Wood’s Sure-Flex couplings use a rubber (EPDM), neoprene, or Hytrel sleeve and have exceptional torsional flexibility. These reliable designs deliver easy installation without bolts, gaskets, covers or seals, while providing superior flexibility and the ability to absorb extreme torsional shock. The couplings are available with a choice of EPDM, Neoprene, or Hytrel sleeve flex elements to suit the needs of the specific applications. The Sure-Flex range offers a wide selection of flange types and bushing mount options, with bore sizes available to order. It also offers excellent shock loading capability as well as a 4-way flexing action, which can accommodate all types of vibration, misalignment and end-float. The design of the coupling provides customers with a reliable coupling which is easy to install, thanks to its innovative design. Remove all components from their boxes, and loosely assemble the coupling on any convenient surface. First, determine the size and type of components being used. The Sure-Flex coupling from TB Wood’s has been awarded an ATEX certification, which allows the coupling to be installed in some potentially explosive atmospheres, the coupling is rated as Device Group “II”, Category “2”, Material Group “G” for Gas and “D” for dust, Kind of Ignition “c”, Temperature T4 ( <135C) for EPDM or Hytrel Sleeves, and Temperature T5 ( <100C) for Neoprene or Urethane Sleeves. SURE-FLEX COUPLINGS F118 Installation Instructions Sure-Flex flanges (outer metallic parts) and sleeves (inner elastomeric members) come in many sizes and types.
