Industrial SRJ200543A USNTC02 Carr Sub Assembly

The Rexnord SRJ200543A Carrier Sub Assembly is a Planetgear carrier subassembly for SRJ-series gear drives, representing the 5.74 variant in Rexnord’s planetary reducer lineup, identified by part number SRJ200543A and the catalog code USNTC02, with Atlas and Polaris drive sizes listed as compatible. Manufactured by Rexnord for use within the Planetgear family, this carrier subassembly functions as the central carrier that houses the planet gears in SRJ speed reducers, and it is intended as a replacement part during service, refurbishment, or routine maintenance of Atlas- and Polaris-sized installations. As part of Rexnord’s Planetgear line, the SRJ200543A Carrier Sub Assembly aligns with the SRJ platform’s design for Atlas and Polaris drives, and its USNTC02 designation helps identify the specific revision used in factory assemblies or field replacements. Engineered to meet Rexnord’s specifications for Planetgear SRJ units, the SRJ200543A carrier subassembly provides the structural support and alignment necessary for reliable gear engagement, helping technicians restore performance in older Atlas- and Polaris-series installations without introducing non-OEM components.
