UD is a standard duty bearing inserts series for insert bearing selection for compatible housings or replacement assemblies. The page keeps the complete catalogue drawing and model-by-model dimensional reference together for RFQ selection.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
UD is a standard duty series configured around flush-back bearing insert. Its catalogue definition uses flush-back insert; see table, with individual bore and dimensional variants retained in one model table.
This product page groups the complete catalogue series under one title. Engineers can compare the available unit numbers inside the dimensional reference instead of moving between many nearly identical SKU pages.
Series selection works best from the machine interface outward: mounting face, shaft, locking method and finally the exact catalogue line. Related bearing families can be compared from the main bearing index. Browse related bearing families.
UD is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
The primary configuration is flush-back bearing insert, intended for insert bearing selection for compatible housings or replacement assemblies.
The catalogue identifies flush-back insert; see table for this series; confirm the exact row before ordering.
Series attributes are separated from model dimensions here. This makes the page easier to scan while keeping the original line-by-line dimensional reference intact below.
| Series | UD |
|---|---|
| Catalogue Reference | Part B, page B128 |
| Product Family | Bearing Inserts |
| Duty Classification | Standard duty |
| Locking / Mounting Method | Flush-back insert; see table |
| Inner Ring / Bore Form | Flush back on both sides |
| Housing / Configuration | flush-back bearing insert |
| Material Note | Material varies by unit; confirm selected model |
For replacement work, compare the drawing with the installed housing rather than relying on a familiar series code alone. Mounting dimensions and locking details are the better confirmation points.
UD is relevant when mounted bearing unit assembly requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
For replacement of compatible housed inserts, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
UD is relevant when custom machinery using spherical-OD inserts requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Use this catalogue table for the final unit-number check. It preserves the source row order, dimensional columns and metric/inch alternatives on one reference image.
Begin with the machine mounting envelope, then confirm the shaft and locking arrangement. A similar series code does not guarantee the same center height, bolt pattern, cartridge fit, slot geometry or inner-ring dimensions. In this family, the intended role is insert bearing selection for compatible housings or replacement assemblies.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | outer-ring/housing compatibility |
| 3 | inner-ring width and locking method |
| 4 | seal and relubrication requirement |
Before quotation, confirm the source row that matches the required shaft and housing dimensions. Any option not stated for that row should be treated as an RFQ item rather than assumed as standard.
A useful RFQ includes the target model or shaft size, mounting dimensions, quantity and any environment requirement. That gives the quotation review enough information to confirm the catalogue row. Ever Power Netherlands Branch can review the quotation basis against the same reference.
