Adapter-style spacer model is characterized by unitized center assembly that “drops” in/out for fast installation or removal. Series 71 encompasses original 4- and 6-bolt designs, and utilizes scalloped disc profile for reduced stiffness and optimal torque transmission.
Adapter-style spacer model is characterized by unitized center assembly that “drops” in/out for fast installation or removal. Series 71-8 features 8-bolt design for higher torque capacities compared to 4- and 6-bolt designs.
Non-adapter style spacer coupling consists of just three main components (two hubs and center spacer), translating into a low weight, high torque design that is well-suited for general purpose industrial applications. Typical applications include motor and turbine driven pumps, compressors, fans, synchronized rollers, wire feeders and blowers.
Adapter-style spacer design enables quick “drop in” installation and removal without moving connected equipment. Balanced to AGMA Class 9 and compliant to API 610 as manufactured, the XTSR71 is ideally suited for critical process pumps, fans, and compressor drive applications. The XTSR71 coupling also meets API 671 when specified.
Directly replaces lubricated gear couplings commonly found in many pulp and paper applications with long spans between connected equipment. The XTSRGA coupling bolts up to the existing AGMA Standard rigid gear coupling hubs, replacing the floating shaft assembly.
Designed for long span applications where shaft spacing exceeds maximum length of standard fully machined spacer designs (XTSR52 / XTSR71).
The single flex element design accommodates angular misalignment only. Typically used in three-bearing applications where radial load is supported by the coupling, such as single bearing generators.
