K15008XP0 and J15008XP0 are reference models for LYDL PX15008 open and PX15008UU double sealed, sized 150 × 166 × 8 mm.
On a shallow platform, closure choice and retaining-cover design must be reviewed together. Check which ring face receives the clamp load and whether the cover clears the sealed version. The shared envelope does not establish a common retainer drawing or identical mounted behavior.
Send the support-plate section, fastening arrangement and required platform performance for a comparison of the two LYDL configurations.
K15008XP0 and J15008XP0 are the KAYDON references for LYDL PX15008 open and PX15008UU double sealed. These 150 × 166 × 8 mm Type X options share boundary dimensions, while the chosen closure must be checked against the retaining cover and lubrication plan.
For a shallow rotating platform, examine the housing, fasteners and ring-contact faces as one assembly. Adding integral seals does not correct an unsuitable support plate or establish how accurately the assembled axis will run.

See the LYDL metric Type X listing for the catalog grouping. Confirm the actual material, internal setting and lubrication on the supply drawing.

A thin bearing ring does not remove the need for a stable seat. Review the support beneath the locating face, the nearby openings and the way the housing connects to the rest of the machine. A plate that looks substantial in an isolated section may be supported only at widely separated attachment points.
Identify the load path from the rotating component through the bearing to the base. Include both process loads and clamping forces. Where the base or cover is flexible, assess the assembled structure rather than assigning all measured displacement to the bearing.
Specify the surfaces that control location and the surfaces that merely provide clearance. This distinction helps the machinist and inspector avoid treating a cosmetic cover surface as a functional datum. Keep the machining and inspection datum scheme consistent with the final mounting arrangement.
If a lightweight housing is required, validate the chosen geometry under the representative loads and fastening conditions. Neither the catalog load rating nor a free-state ring measurement can establish the stiffness of that complete structure.

The following values describe KAYDON K15008XP0 and J15008XP0, not certified LYDL performance.
| Catalog rating | Dynamic | Static |
|---|---|---|
| Radial | 8,296 N | 15,347 N |
| Axial | 13,033 N | 38,383 N |
| Moment | 492 N·m | 1,213 N·m |
These limits are not simultaneous. The dynamic basis is one million revolutions of L10 life; static values assume rigid ring support. Obtain the LYDL rating basis before calculating application life. The LYDL series table labels force capacities in “kg”; this page does not silently reinterpret those entries as newtons.
For the sealed J15008XP0 reference, Kaydon lists 420 rpm at loads up to 20% of dynamic capacity, and 0.35 N·m maximum no-load torque with standard internal fit and lubricant, at room temperature under 5 lbf thrust. These are conditional reference figures, not unrestricted limits for the supplied LYDL bearing.
A possible PX15008 application is a low-profile platform inside an inspection or automation module. The shallow 8 mm bearing width can support a compact axial layout, but the platform still needs space for locating faces, retainers and lubrication provisions.
Prepare the assembly section with the final mounting bolts, base attachments and any access openings visible. A platform bolted to a rigid laboratory block can behave differently from the same unit attached to a production panel. Use the intended interface when deciding whether prototype measurements represent the machine.
During a loaded check, measure at more than one angular position if the process requires consistent behavior around the rotation. Document the measurement radius and load application point. This study supports application review; it is not a published positioning or stiffness specification for PX15008.

The retainer should act on the intended bearing face without touching unintended components. Establish the contact geometry from the approved drawing, including corner relief and the clearance needed by moving parts. Do not use additional bolt torque to compensate for a locating surface that does not seat correctly.
Define an assembly sequence and fastener settings with the responsible design engineer. Then measure the selected running characteristic after the ring is seated and again after retention is complete. If the result changes materially, investigate where the clamping load enters the assembly.
Inspect for trapped debris, raised edges and uneven contact before repeating the build. A repeatable test is more informative than successive undocumented adjustments to individual screws. Retain the settings from the accepted sample and identify the tools used to achieve them.
When comparing PX15008 with PX15008UU, check seal relief in addition to the ring-contact face. A cover suitable for the open version still needs a clearance review before sealed samples are fitted.
Use PX15008 — Open and PX15008UU — Double Sealed for LYDL purchasing. The corresponding KAYDON references are K15008XP0 and J15008XP0, respectively.
KAYDON K means steel construction without seals or shields; J means steel construction with two nitrile seals. X identifies four-point contact, P a standard snap-over separator, and 0 Kaydon class 1 / ABEC 1F. These codes do not certify the LYDL configuration.
An equivalent seal description does not establish cover clearance. INA / Schaeffler CSXU050-2RS and NSK’s inch-design NBX family with DD illustrate different names for sealed arrangements. They are not specified substitutes for the 150 mm seat. Require each proposed bearing’s section drawing before approving a common platform retainer.
Choose acceptance measurements that relate to the finished platform: for example, runout at a defined radius or displacement under a stated force. Record whether the drive coupling and process hardware are attached. A bearing-only inspection and a platform inspection should remain distinguishable in the documentation.
For supplier communication, include the functional seat dimensions and the assembly datum scheme. Ask which bearing characteristics will be inspected before shipment and which require testing after mounting. This makes responsibility clearer when a complete unit fails a performance requirement.
Protect the locating faces during storage and installation. Keep the closure choice on the assembly record: PX15008 needs the specified working lubrication, while PX15008UU requires confirmation of grease and seal clearance.

Incoming checks describe the bearing under their stated conditions. The mounted result also depends on seat geometry, fits, retention and support stiffness. Compare inspection methods and assembly stages before concluding that either measurement is wrong.
Use one retainer only after checking both section drawings. It must load the intended ring face while clearing the sealed construction. Compare resistance after seating and after final retention using a controlled method; extra bolt torque is not a remedy for interference or unsuitable contact geometry.
Use a representative attachment whenever base flexibility can influence the result. If a different fixture is necessary, identify that limitation and establish how results will transfer. A rigid bench fixture should not silently stand in for a flexible production interface.
Provide the assembly stage, fastener settings, measurement method and the angular location relative to the housing. Include the load and whether the drive is connected. This information helps distinguish repeatable geometry effects from an inconsistent hand check.
No. Its different section changes the installation envelope and the bearing selection, but it does not correct an unsuitable base. Review the support and the bearing together, then validate the revised arrangement against the required mounted performance.
PX15013 retains a 150 mm bore with a different section and housing envelope. PX20008 keeps the 8 mm section while moving to a larger seat; evaluate that page when the platform opening drives the design.
