UC300 Heavy-Duty Bearing Inserts
Compare mounting style, shaft locking, bore range and installation envelope before selecting the alternative.
UK Tapered Bore Bearing Inserts
On UK-SERIES, the mechanical form is tapered-bore insert bearings for adapter-sleeve mounting, the construction is chrome-steel insert bearing construction, and the shaft connection is adapter sleeve locking. The machine-side comparison should cover shaft bore, inner-ring width, outer-ring form and housing seat.
Before loosening both supports, establish a useful machine datum or mark their original positions. Compare centre heights and the natural shaft line through the assembly. If one new housing is taller, narrower or located differently, tightening it first can force the second bearing to accommodate the mismatch rather than allowing the shaft to sit freely.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

This product family is commonly reviewed for conveyors, fans, roller tables and general industrial housings using replaceable inserts. Actual load, speed, cleaning and contamination conditions should be stated for the ordered position.
Alignment Across Paired Supports
A bearing unit works as part of a shaft-support system. When two or more housings carry the same shaft, replacing one position without considering the others can create alignment problems even if the individual bore size is correct.
Before loosening both supports, establish a useful machine datum or mark their original positions. Compare centre heights and the natural shaft line through the assembly. If one new housing is taller, narrower or located differently, tightening it first can force the second bearing to accommodate the mismatch rather than allowing the shaft to sit freely.
During installation, start the mounting hardware lightly and let the shaft establish its natural position through the support points before final tightening. This is especially helpful when the frame is older or when the machine has been repaired around one bearing location. The goal is not to use the housings as alignment jacks.
After commissioning, compare the two supports during inspection. Unusual temperature, noise or movement at one side is not proof of a bearing defect by itself, but it is a useful signal to review alignment, mounting and lubrication before another spare is ordered.
Paired-support geometry
Use the drawing to compare shaft bore, inner-ring width, outer-ring form and housing seat. Read the printed values rather than scaling the illustration; for modified equipment, send current machine measurements with the enquiry.

Applications
Conveyors
UK205 can be considered for conveyors where its tapered bore geometry matches the machine. Check the machine-side interface shown in the drawing before final model approval.
Fans & General Machinery
For fans & general machinery, the adapter sleeve arrangement changes installation access and shaft retention. Confirm that detail before standardising the spare.
Replacement & MRO
In replacement & mro service, use the construction of UK205 only where the actual moisture, contamination and cleaning conditions match the selected product family.
