UP / UFL Silver Series Bearing Units
Compare mounting style, shaft locking, bore range and installation envelope before selecting the alternative.
K / U Silver Series Bearing Inserts
K / U Silver Series Bearing Inserts is a light-duty bearing inserts for silver series housings using zinc-alloy / light-duty housed construction; this version uses setscrew or eccentric locking, by insert series. For fit approval, check shaft bore, inner-ring width, outer-ring form and housing seat.
Before dismantling the support, capture the as-installed condition. Measure the shaft centre above the mounting face, record the fixing-hole locations, and photograph any spacers or non-standard hardware. If the base has been welded, slotted or repaired, treat those dimensions as the current machine reality. An old equipment manual can still be helpful, but it should not overrule what is physically present on the machine today.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.

Retrofit-focused buying notes
K / U Silver Series Bearing Inserts is a light-duty bearing inserts for silver series housings using zinc-alloy / light-duty housed construction; this version uses setscrew or eccentric locking, by insert series. For fit approval, check shaft bore, inner-ring width, outer-ring form and housing seat.
The surrounding use case is typically light-duty conveyors, compact auxiliary machinery and modest shaft-support positions, but the final choice still depends on the actual machine position and service conditions.

Legacy Footprint Review
Replacement work on an older machine is rarely as simple as reading the code on the bearing housing. The useful question is whether the new unit will occupy the same physical relationship to the shaft and frame after years of repairs, shimming or local modifications.
Before dismantling the support, capture the as-installed condition. Measure the shaft centre above the mounting face, record the fixing-hole locations, and photograph any spacers or non-standard hardware. If the base has been welded, slotted or repaired, treat those dimensions as the current machine reality. An old equipment manual can still be helpful, but it should not overrule what is physically present on the machine today.
Keep the removed unit until the replacement has been checked. The old part can reveal details that a worn label does not: which side maintenance staff approached, where the locking hardware sat, whether a cover was used, and how much clearance existed around the housing. Those clues are especially valuable when two candidate products share the same bore yet use a different footprint or shaft-retention method.
For purchasing, the best record is a short package containing the complete old code, the measured interface, and one wider photo of the installation. This reduces the chance of ordering a visually similar unit that only fails when the shutdown is already underway. Once a replacement fits successfully, update the spare-parts record with the confirmed dimensions rather than keeping an uncertain legacy description.

As-installed dimensions to check
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
Compact Conveyors
K005 / U005 can be considered for compact conveyors where its silver series insert geometry matches the machine. Outer-ring shape and housing seat must match the selected mounted housing.
Auxiliary Machinery
For auxiliary machinery, the setscrew (k) / eccentric collar (u) arrangement changes installation access and shaft retention. Confirm that detail before standardising the spare.
Packaging Equipment
In packaging equipment service, use the construction of K005 / U005 only where the actual moisture, contamination and cleaning conditions match the selected product family.
