1 SPECIFICATION/HOW TO ORER/NOMENCLATURE PARA-FLEX SPECIFICATION PARA-FLEX s employ a molded, non-lubricated elastomeric flexing member loaded in shear. The flexible member is compounded natural or neoprene rubber with textile cord reinforcement throughout and has an extra layer of reinforcement adjacent to the split for added durability. The compound of natural rubber element shall be suitable for operation in ambient temperature from -45 F to +80 F; Neoprene -40 F to +0 F. The flexible element is attached by clamping between axially separable rings with exposed SAE grade 8 cap screws 4. The couplings are designed to be capable of accommodating combined misalignments of 4 angular, / 8 parallel, and 5 / 6 end float at the full rating of the coupling without restricting the rating or life of the coupling. The flexible element must be replaceable without disturbing the coupled equipment and without the requirement for realignment. The coupling assemblies have optional methods of attachment to the shaft including but not limited to: clearance fit, interference fit or TAPER-LOCK bushings. Clearance fits and interference fits are supplied with an industry standard keyway and two set screws, one over the key and one at 65. Spacer s consist of two hubs and a pre-assembled center assembly. The center assembly is readily removable to facilitate maintenance on pumps or other connected equipment and must be replaceable without disturbing the coupled equipment and without realignment. PX40: 4_ angular, /6 parallel, 3/6 end float. PX0: 4_ angular, /8 parallel, /4 end float. 3 PH & PF: angular, /6 parallel, 3/6 end float. 4. FBX style couplings utilize class 0.9 metric cap screws.

4 SPECIFICATION/HOW TO ORER/NOMENCLATURE Other s -- POLY-ISC SPECIFICATION POLY-ISC s are a pin type coupling using a molded polyurethane disc. The physical properties of the disc allow for the cushioning of shock loads and the resistance to most common chemicals such as acids, alkalis and petroleum products. The disc has an operating range of -90 F to +70 F. The flexible disc is captured through metallic pins, utilizing a light press fit over the pins to prevent the accumulation of abrasive particles between the disc and pins. The pin holes are barreled to allow angular misalignment and the flexible disc allows /3 parallel misalignment. The disc has spacer buttons to achieve automatic flange spacing which speeds up installation. Both flanges are machined all over and are taper bored to receive TAPER-LOCK bushings to permit quick and easy installation on shafts of equal or different diameters. HOW TO ORER Consists of: () TAPER-LOCK Flanges () isc NOMENCLATURE 3-/4 - H (O.. of ) Type of T-L Flange H-Bushing installs from hub side F-Bushing installs from flange side RIGI SPECIFICATION Rigid s provide a connection between two perfectly aligned shafts. Flanged Rigid s consist of two flanges joined by bolts and taper bored for TAPER-LOCK bushings to connect shafts of the same or different diameters. Ribbed Rigid s are axially split to clamp on shafts of the same diameter and held together by bolts. The coupling uses one key over the entire length and permits quick and easy installation and removal.

10 ENGINEERING/ TECHNICAL Selection Methods: -FLEX, PARA-FLEX, GRI-LIGN, GEAR, POLY-ISC, & Rigid s HP/00 METHO: Step : Obtain required service factor from Service Factor Tables on pages PT--68 and PT--69. Step : etermine the application HP per 00 RPM: HP 00 RPM = Motor HP x 00 x Service Factor RPM Step 3: From Rating Tables, find a rating equal to or greater than the HP/00 RPM. Note coupling size from lefthand column. Step 4: Check maximum RPM capability. Step 5: Check maximum bore capacity. If maximum bore is exceeded, move to larger size with adequate bore but be sure maximum RPM of coupling is not exceeded. NOTE: If spring set motor brake is used, and brake HP is greater than prime mover, use brake HP in place of motor HP. ESIGN HP METHO: Step : Obtain required service factor from Service Factor Tables on pages PT--68 and PT--69. Step : etermine application HP: HP esign = HP x SF Step 3: From rating tables, select appropriate coupling RPM column and find a rating equal to or greater than HP design. Note coupling size from left hand column. Step 4: Check maximum RPM capability. Step 5: Check maximum bore capacity. If maximum bore is exceeded, move to larger size with adequate bore but be sure maximum RPM of coupling is not exceeded. TORQUE METHO: Step : Obtain required service factor from Service Factor Tables on pages PT--68 and PT--69. Step : etermine torque required for application. Torque (in lbs.) = 6305 x HP x SF RPM Step 3: From Rating Tables, find a rating equal to or greater than the torque. Note coupling size from lefthand column. Step 4: Check maximum RPM capability. Step 5: Check maximum bore capacity. If maximum bore is exceeded, move to larger size with adequate bore-but be sure maximum RPM of coupling is not exceeded. NOTE: If system peak torque is known and is non-reversing, start at Step 3. If system peak torque is known and reversing, multiply by.0 and start at Step 3. --FLEX COUPLINGS PAGE PT-- GRI--LIGN COUPLINGS PAGE PT--38 PAGE PT--57 PT--67
