4-WAY FLEXING ACTION
absorbs all types of
shock, vibration and misalignment
Sure-Flex coupling sleeves have an exceptional ability to absorb torsional shock and dampen torsional vibrations. The EPDM and Neoprene sleeves wind-up approximately 15" torsionally at their rated torque. Hytrel sleeves will wind-up about 7".
The unique design of the Sure-Flex coupling's teeth allows for the absorption of angular misalignment without wear. Alignment of the coupling requires using only a scale and calipers.
Parallel misalignment is absorbed without wear or appreciable energy losses. The lateral flexibility of the coupling sleeve minimizes radial bearing loads normally associated with parallel misalignment. This feature also allows for easier installation by the use of components bored for slip fits without fretting corrosion occurring at the shaft. Only a straight-edge and feeler gauge are required
Sure-Flex couplings may be used in applications with limited axial shaft movements. The axial compressibility of the EPDM and Neoprene sleeves allows for shaft endfloat without the absolute transfer of thrust loads.
Sure-Flex can be installed quickly and easily, because there are no bolts, gaskets, covers or seals. Alignment can be checked with a straightedge placed across the outside of the precision-machined flanges. No special tools are needed for installation, alignment or removal.
The teeth of the sleeve lock into the teeth of the flanges without clamps or screws, tightening under torque to provide smooth transmission of power. There is no rubbing action of metal against rubber to cause wear. Couplings are not affected by abrasives, dirt, or moisture. This eliminates the need for lubrication or maintenance, provides clean, dependable, quiet performance.

Flexible sleeves for Wood's Sure-Flex couplings are available in four materials (EPDM Neoprene, Hytrel and Urethane) and in three basic constructions.
JE-JES-JN-JNSJ sleeves are molded EPDM rubber (E) or Neoprene (N). They are available in one-piece solid construction (JE, IN) or one· piece split construction (JES, JNS). These sleeves may be used in any Sure-Flex flange within a given size. | |||
E-NThese 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-HS-UH (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. |

*On applications involving varying torque loads, design around the maximum load. Then determine the resulting service factor at minimum load. If this value is greater than 4.0, special coupling alignment will be required (see page F1-18).
Caution: Applications involving reciprocating engines and reciprocating driven devices are subject to rotational vibrational critical speeds which may destroy the coupling. The factory can determine these speeds when the rotational inertia (WR2) of the driveR and driveN units is known.
Example: For 150 HP @ 1750 RPM and 1.5 Service Factor - Use #13 EPDM or Neoprene or #10 Hytrel or Urethane.
HP @ 100 rpm = HP x Service Factor x 100/ coupling RPM
Example: For 5 HP @ 55 RPM and 1.25 Service Factor:
HP @ 100 = 5 x 1.25 x 100/55 = 11.36
Use #12 EPDM or Neoprene or #9 Hytrel with rating of 11.4 HP.

Type J flanges size 3 and 4 are manufactured of sintered carbon steel. The powdered metal manufacturing process provides high dimensional accuracy and uniform material properties for high strength. Size 5 and 6 are made of high strength cast iron. All flanges are bored-to-size for a slip fit on standard shafts. The outside diameter of the flange is machined so the surface can be used to check alignment without a special tool. Type J flanges can be used with sleeves of any construction except the Hytrel. Each flange has a keyseat and one (1) setscrew over the keyway.
Type J Sure-Flex Couplings are bored-to-size. Normally, they employ the one-piece JE sleeve, or the onepiece JES sleeve with saw cut to permit replacement where there is Insufficient gap between shafts.
Spacing between internal flange hubs equals G. Spacing between shafts should be greater tnan 1/8 in. and less than L minus .85 times the sum of the two bore diameters.

Some large bore Type S flanges are supplied with shallow keyseats. In these cases, a rectangular key is furnished. The bores involved are listed above.
▲ 1-5/8 for 1-1/2 bore, 1-5/16 for 1-5/8 bore.
Type B flanges are made of high-strength cast iron the same as Types S, C and SC Sure-Flex flanges. Type B, however, is designed to accommodate Wood's Sure-Grip Bushing for easy installation and removal.
Sure-Grip Bushings offer convenient mounting of the flange 10 the shaft securely without setscrews. They are tapered and are split Through both the bushing flange and taper to provide a clamp fit, eliminating wobble, vibration and fretting corrosion. This is the same bushing used in Wood's sheaves and pulleys and is readily available everywhere.

Spacer couplings are available having the most popular between shaft dimensions. Other spacings can be achieved by mixing flanges.
The "Standard" column provides spacings using identical flanges; the "Combination" column mixes flanges; the column headed "Semi-Spacer" uses one flange that is not made for spacer coupling applications and thus does not have a detachable hub.

Sure-Flex. Type C Clamp Hub flanges employ integral locking collars and screws to assure a clamp fit on the shaft. One setscrew is furnished over the key. They are designed primarily for applications where flanges must be removed from one or both shafts without moving either the driver or doven units. A typical application is a screw compressor which uses a replaceable face seal around the input shaft.
Type C Clamp Hub Couplings normally use Hytrel sleeves. However, any of the sleeves shown can be used. Type C couplings may often be used where spacer couplings are required.
Spacing between internal flange hubs equals G.

Sure-Flex flanges (outer metallic parts) and sleeves (inner elastomeric members) come in many sizes and types. First, determine the size and type of components being used. Remove all components from their boxes, and loosely assemble the coupling on any convenient surface. (Do not attempt to install the wire ring on the two-piece E or N sleeve at this time.) Also check maximum RPM values in the table against operating speed. All rubber sleeves (EPDM and Neoprene) have the same ratings for a given size and may be used interchangeably. However, because rubber and Hytrel sleeves have completely different ratings, they never should be used interchangeably.
Inspect all coupling components and remove any protective coatings or lubricants from bores, mating surfaces and fasteners. Remove any existing burrs, etc. from the shafts.
Slide one coupling flange onto each shaft, using snug-fitting keys where required. When using Type B flanges, follow the instructions furnished with the Sure-Grip bushing.
Position the flanges on the shafts to approximately achieve the Y dimension shown In the table. It is usually best to have an equal length of shaft extending into each flange. Move one flange to its final position. Torque fasteners to proper values. Slide the other flange far enough away to install the sleeve. With a two-piece sleeve, do not move the wire ring to its final position; allow it to hang loosely in the groove adjacent to the teeth.
Slide the loose flange on the shaft until the sleeve is completely seated in the teeth of each flange. (The "Y" dimension is for reference and not critical.) Secure the flange to the shaft. Different coupling sleeves require different degrees of alignment precision. Locate the alignment values for your sleeve size and type in the table.
Check parallel alignment by placing a straight-edge across the two coupling flanges and measuring the maximum offset at various points around the periphery of the coupling without rotating the coupling. If the maximum offset exceeds the figure shown under "Parallel" in the table, realign the shafts.
Check angular alignment with a micrometer or caliper. Measure from the outside of one flange to the outside of the other at intervals around the periphery of the coupling.
Determine the maximum and minimum dimensions without rotating the coupling. The difference between the maximum and minimum must not exceed the figure given under "Angular" in the table. If a correction is necessary, be sure to recheck the parallel alignment.

Note: Values shown above apply if the actual torque transmitted is more than ¼ the coupling rating. For lesser torque, reduce the above values by ½.
*Type H and HS sleeves should not be used as direct replacements for EPDM or Neoprene sleeves.
If the coupling employs the two-piece sleeve with the wire ring, force the ring into its groove in the center of the sleeve. It may be necessary to pry the ring into position with a blunt screwdriver.
Install coupling guards per OSHA requirements.
CAUTION: Coupling sleeves may be thrown from the coupling assembly with substantial force when the coupling is subjected to a severe shock load or abuse.
