Rexnord SRB200543A Sub Assembly

Rexnord SRB200543A Carrier Sub Assembly is a replacement carrier for Rexnord Planetgear speed reducers, specifically the SRB 5.74 size. As a carrier sub-assembly, it sits in the planet gear stage to support the planet gears and facilitate torque transfer within the Planetgear reduction set. This part is identified by the model SRB200543A and is specified with an outer diameter of 7.86 inches, matching the SRB 5.74 configuration. The SRB200543A is designed as a direct swap-in replacement for compatible Rexnord Planetgear units, helping maintain gear alignment and performance in compact, high-torque drive systems. In routine maintenance of Rexnord Planetgear speed reducers, this carrier sub-assembly plays a critical role in preserving the integrity of the planetary gear train and the overall durability of the reducer.
