RCJTC INDUSTRIAL SERIES CONCENTRIC COLLAR
• Same basic design as RCJT, except they use 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.
• Bolt hole spacing dimensions are interchangeable with
the RCJT Series and most competitive units.
• Units are factory prelubricated. A grease fitting is provided
for relubrication.
• Safety end caps are available for selected sizes.
