Timken - Ball Bearing Housed Units

BALL BEARING HOUSED UNITS
BALL BEARING HOUSED UNITS • CAST-IRON FLANGED UNITS • RCJTC
RCJTC INDUSTRIAL-SERIES
CONCENTRIC COLLAR
• 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.
H
• 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.
• Safety end caps are available for selected sizes.
Suggested shaft tolerances:
1⁄2 in. – 1 15 ⁄16 in., nominal to -0.013 mm, -0.0005 in.;
To order, specify UNIT and SHAFT DIAMETER.
Example: RCJTC 1 3 ⁄16 in.
