UCTX00 Series Take Up Bearing Units — Medium Duty, Setscrew Locking
A take-up unit combines a mounted bearing with a slotted cast iron housing that slides along a frame rail or between guide faces, driven by an adjusting screw. The slot travel (controlled by dimensions N1 and N2 — slot width and slot length) allows the bearing centreline to be moved axially or laterally relative to the drive structure after installation, tensioning a belt, chain, or timing drive without removing the bearing from the shaft. Once the correct tension is set, the housing is locked in position by tightening the frame bolts through the slot. This combination of bearing and tensioning mechanism in a single unit reduces the number of components on a conveyor or drive frame, lowers installation time, and makes re-tensioning after belt stretch a tool-only operation without shaft removal.
The UCTX00 is the medium-duty step-up from the standard UCT200 in the take-up housing format, mirroring the UCPX00 relationship to UCP200 in the pillow block range. The heavier housing cross-section and higher-rated UC insert bearing of the UCTX00 address the two most common failure modes of a standard-duty take-up unit under elevated belt tension: housing deformation under sustained load that changes the slot alignment, and insert bearing fatigue from loads that exceed the UCT200 capacity. When L10 calculations show UCT200 life below 20,000 hours under the actual belt tension and speed combination, the UCTX00 is the next step before moving to the UCT300 heavy duty series.


Key Features
⚙
Heavy-Section Take-Up Frame
Heavier cast iron housing cross-section delivers higher bending stiffness and resistance to frame deformation under sustained high belt tension than UCT200 at equivalent bore sizes.
🔧
Setscrew Locking — UCX Insert
Higher-rated UCX series wide inner ring insert with higher C and C0 values than UCT200 equivalent at same bore size. Same dual 120° setscrew geometry.
⇨
Full Slot Travel Range
N1, N2 slot dimensions provide the same proportional travel range as UCT200 for equivalent bore sizes. Tensioning procedure is identical.
📏
Metric and Inch Bore
25–85 mm metric bore with inch bore variants per housing size.
✅
GB / ISO / ANSI / JIS Compliant
Drop-in replacement for UCTX-pattern medium duty take-up units.
▭
Solid Base Option
Hollow base standard. Solid base (SB) on request for highest belt-tension installations.
