2 Dura-Flex couplings are designed from the ground up using finite element analysis to maximize flex life T Wood s Dura-Flex couplings "split-in-half" element design allows for easy element installation/replacement without moving connected equipment or disturbing the shaft connection. Spacer design can accommodate a large range of shaft spacing with few parts. Patented design of the urethane bond to the leading edge of the steel shoe bolted to the hub, minimizes bond stress for long coupling life. These couplings are highly flexible and able to accommodate shaft misalignments (1/16" parallel misalignment and 4 angular misalignment) while minimizing torsional vibration and preventing damage to connected equipment. Specially formulated polyurethane material provides superior weathering, chemical resistance, and dynamic properties. Patent No. 5,611,732 Features (Metric) Torque up to 4.50 knm; 39,500 in.lbs. Easy to assemble/replace High misalignment ratings No maintenance/lubrication Part-for-part interchangeable with industry standard design In-stock versatile spacer design can accommodate many configurations with few parts ore-to-size (TS), Sure-Grip bushed (QD), and Taper-Lock hubs are available ll dimensions including hardware and fasteners Specially designed, split-in-half element can be easily replaced without moving any connected equipment. pplications Dura-Flex couplings can be found hard at work in many industries such as water treatment, paper and metal processing, power generation, and material handling. These couplings are ideal for a wide variety of applications with uniform to heavy shock loads including: Pumps Fans/lowers Compressors Electric Motors Conveyors Dura-Flex couplings withstand harsh conditions in wastewater facilities. 2 T Wood s P-1956-TW-4 1/11

Conditions subject to extreme temperatures, abrasive dusts, corrosive liquids, excessively high starting torques, etc., must be considered as extra heavy shock loads. These conditions will increase service factors. Consult T Wood s for these selections. Calculate Design Horsepower or Design Torque If Prime Mover is a 970, 1450, or 3000 RPM motor Design KW = Prime Mover KW x Service Factor Go to page 4 and reference the corresponding motor RPM column. If Prime Mover is not one of the three speeds listed above Design 100 RPM = (Primer Mover KW x Service Factor x 100) / Coupling RPM Go to page 4 and reference 100 RPM column. If Using Prime Mover Torque Design Torque = Prime Mover Torque x Service Factor Go to page 4 and reference Torque column.
