This series has the same basic design as RCJT, except it uses the concentric collar rather than the self-locking eccentric collar as the shaft-locking device
All units are equipped with GC-KRRB wide inner ring concentric collars
The spherical outside diameter mounted in the corresponding machined housing seats provides the initial self-alignment
The bolt-hole spacing dimensions are interchangeable with the RCJT series and most competitive units
The units are factory-prelubricated A grease fitting is provided for relubrication
