INCH TTU TAKE-UP UNITS
Inch TTU TAKE-UP UNITS
• The same care taken in the selection of stationary pillow
blocks also must be applied to selecting the proper
take-up unit.
• Load requirements should be carefully evaluated before
specifying a particular take-up assembly.
• The frame assembly and adjusting screw of TTU units are
made of steel.
• The bearing housing is cast iron. Steel or ductile iron
housings are additional options.
• Units include housing for adapter-mounted bearings only,
for either fixed or float position (be sure to specify).
• One stabilizing ring is included for fixed-position
assemblies.
• Sealing is triple-ring labyrinth or end closures.
• For extremely contaminated environments, the DUSTAC
seal is suggested. See page D-80 for more information.
