Keep the evidence with the model shortlist
The models on this page illustrate bearing roles; they are not confirmed replacements for an unspecified machine. Keep the original complete marking, machine position, load and speed duty, temperature, lubricant and mounting arrangement together. Check the candidate's recorded values below and leave unreported parameters unknown.

What matters in this application
Position
Separate intermediate hanger, drive-end thrust and tail-end radial support.
Conveyed material
Record abrasiveness, particle size, moisture, chemistry and any hygiene requirement.
Operating condition
Include screw speed, start-up torque, axial thrust, shaft alignment and thermal growth.
Which bearing structures make sense?
Plain hanger bearings
Evaluate the specified bronze, polymer, composite, wood or other approved bearing material.
Check first: Material compatibility and allowable wear matter; do not apply rolling-bearing fatigue equations.
Rolling end supports
Use a properly rated and sealed housing arrangement outside the material path where designed.
Check first: A radial pillow block alone may not provide the required screw-thrust capacity.
Recommended starting points
These candidates illustrate specific roles and envelopes, not a ranked list or interchangeable set. Review each condition before using a model in a design.

— = not reported, or not directly comparable for a mounted unit. Width conventions differ for inserts, complete units and bearing assemblies; inspect the dimensional drawing. Values are read from the current BearingScope records, not estimated from model numbers.
Work through the selection
- Identify hanger and end-support positions from the conveyor drawing.
- Determine material exposure, screw loads and thrust direction.
- Select the appropriate hanger material and separately verify end-bearing loads and housing interfaces.
- Check alignment, expansion allowance, sealing and the approved wear-inspection schedule.
Symptoms worth checking
Hanger squeal or rapid wear
Review material compatibility, lubrication and shaft alignment.
Drive-end heating
Check axial thrust path, lubricant and support setting.
Symptoms are investigation prompts, not a diagnosis. Isolate equipment safely and follow its maintenance procedures before inspection.

Application questions, answered
Are wood hanger bearings always obsolete?
Material suitability depends on the specified conveyor duty. Do not replace a designed material solely because it differs from a rolling bearing.
Can UCP205 carry all screw-conveyor thrust?
Do not assume so. Verify the unit's permissible axial loading and the complete thrust-location arrangement.
