COUPLINGS DISC REXNORD

• The Rexnord Thomas Series 54RDG couplings are reduced diameter gear and grid replacement couplings.

• The Rexnord Thomas Series 54RD couplings are specifically designed as replacements for close-coupled gear and grid couplings, and where overall shaft-to-shaft spacing is minimal. • Materials of construction are identical to the Series 52. Stainless steel disc packs are supplied as standard.

• The Thomas CMR Coupling is engineered to accomodate torque loads up to 3,124,000 lb-in and shaft diameters up to 16.0 inches. • The Rexnord Thomas CMR coupling is ideal for heavy-duty, slow to medium speed applications, where high-starting torque, shock loads, torque reversals or continuous alternating torques are present.

• The Thomas AMR Coupling is engineered to accomodate torque loads up to 3,124,000 lb-in and shaft diameters up to 16.0 inches. • The Rexnord Thomas AMR coupling is ideal for heavy-duty, slow to medium speed applications, where high-starting torque, shock loads, torque reversals or continuous alternating torques are present.

• Thomas XTSRS couplings are single flexing design that accommodate angular misalignment only. • Typically used in three-bearing applications where radial load is supported by the coupling, such as single bearing generators. • Two XTSRS couplings may be combined with intermediate shaft to support full-floating shaft applications. • XTSRS couplings are available in 23 standard sizes with continuous torque capacity up to 2,510,000 lbs-in.

• Thomas XTSRLS couplings are full-floating shaft couplings designed for applications with relatively long distances between connected equipment, either horizontally or vertically.

• XTSR52 couplings are compatible with one, two or three sizes larger hubs and available in 23 sizes ranging from 494 through 5258. • The Thomas XTSR52 Coupling is engineered to accomodate torque loads up to 2,510,000 lb-in and shaft diameters up to 16.0 inches.

• The XTSRGA coupling bolts up to the existing AGMA Standard rigid gear coupling hubs, enabling simple replacement of the floating shaft assembly. • XTSRGA couplings are available in 16 standard sizes with continuous torque capacity up to 1,130,000 lbs-in.

• The Rexnord Thomas XTSR71 spacer disc coupling is a high performance 3-piece design enabling compact packaging for critical operating conditions including API applications. • The Thomas XTSR71 couplings are API 610, ISO 14691, and API 671 (ISO 10441) compliant when specified as well as ATEX II 2GD c T6 certified.

• Modulflex DISC is built under compression allowing torque to move back and forth at high speeds • High precision manufacturing eliminates joint vibration • High strength stainless steel disc set, designed for infinite dynamic load life even with reciprocating forces • Flexible disc design offers infinite dynamic load life and provides angular, radial and off-axis capabilities • Modular design for easy installation

• The CENTADISC-C series torsionally stiff couplings and driveshafts offer a cost-effective, low-maintenance solution for vibration and noise-damping. • The lightweight composite materials ensure safe transmission of high torques and speeds. Built with modularity, CENTADISC-C can be combined with additional CENTA torsional coupling products for optimal adaptation and performance.

• CENTADISC-M series flexible driveshafts are lightweight, making them ideal for high-speed ferries and ships, but with the precision-engineered design, the M series products offer a driveshaft solution for many other industries and applications as well.

• Built for single-bearing electric motor-to-gearbox applications in light rail bogey drives, CENTADISC-T couplings are electrically insulating for extreme loads. Large insulation spans eliminate leakage and high-frequency currents.

• Custom spacer lengths up to 275 inches (7,000 mm) • Continuous torque ratings up to 36,200 lb-in (4,090 Nm) • Shaft diameters up to 12.75 inches and bore capacity up to 5.06 inches
