UK Tapered Bore Bearing Inserts
Compare mounting style, shaft locking, bore range and installation envelope before selecting the alternative.
UC300 Heavy-Duty Bearing Inserts
On UC300-SERIES, the mechanical form is heavy-duty wide inner-ring insert bearings, the construction is chrome-steel insert bearing construction, and the shaft connection is setscrew locking. The machine-side comparison should cover shaft bore, inner-ring width, outer-ring form and housing seat.
Start by reserving a clear shaft line and the envelope needed by the chosen mounting form. Leave realistic room for bolts, collars, grease access and eventual removal. A housing that fits in a CAD model can still become awkward on the shop floor if a guard blocks the fastener path or if a wrench cannot reach the locking feature after the rest of the machine is assembled.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

Design-stage selection notes
On UC300-SERIES, the mechanical form is heavy-duty wide inner-ring insert bearings, the construction is chrome-steel insert bearing construction, and the shaft connection is setscrew locking. The machine-side comparison should cover shaft bore, inner-ring width, outer-ring form and housing seat.
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.
Designing the Support Into New Equipment
New-machine projects allow the bearing position to be engineered before the frame, guards and nearby components become fixed. That makes early interface planning more valuable than simply selecting a familiar housing and drawing the structure around it later.
Start by reserving a clear shaft line and the envelope needed by the chosen mounting form. Leave realistic room for bolts, collars, grease access and eventual removal. A housing that fits in a CAD model can still become awkward on the shop floor if a guard blocks the fastener path or if a wrench cannot reach the locking feature after the rest of the machine is assembled.
The design record should identify the exact product reference, the shaft size, the locking method and the mounting dimensions that locate the unit. Put these items in the bill of materials rather than relying on a generic note such as “flange bearing.” Doing so makes the first build easier to inspect and gives future maintenance teams a better starting point when the same support must be replaced.
Think about spares at the same stage. If several positions could share one product, verify the interfaces deliberately instead of assuming commonality because the shaft diameters match. A small amount of design discipline now can prevent a plant from carrying several almost-identical housings that cannot actually substitute for one another.
Machine drawing review
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
UC305 can be considered for conveyors where its heavy-duty, wider inner ring 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 setscrew arrangement changes installation access and shaft retention. Confirm that detail before standardising the spare.
Replacement & MRO
In replacement & mro service, use the construction of UC305 only where the actual moisture, contamination and cleaning conditions match the selected product family.
