K10008XP0 and J10008XP0 are the open and double-sealed references for the LYDL PX10008 / PX10008UU pair. The nominal size is 100 × 116 × 8 mm.
Evaluate these bearings when the rotating assembly must share its center with cables, a protective sleeve or another service interface. The 100 mm bore locates the bearing; usable passage depends on the complete hub and routing design. Choose the closure after checking where services move and how the assembly is protected.
Submit the hollow-axis section and service-motion envelope for a LYDL configuration review.
K10008XP0 and J10008XP0 provide the KAYDON reference identities for LYDL PX10008 open and PX10008UU double sealed. This combined page covers the LYDL 100 × 116 × 8 mm bearing options for a metric Type X arrangement.
A central service route can be the deciding feature of a rotary assembly. Before choosing the closure, establish where the stationary and rotating components lie, how the services move and what prevents them from approaching the bearing faces.

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

The bearing bore is a mounting dimension. A hub or tubular shaft normally occupies part of it, and the finished passage can be reduced further by fasteners, liners or strain-relief components. Prepare a full section through the axis rather than allocating cable space from the 100 mm dimension alone.
Mark which components rotate and which remain stationary. For cables that flex during motion, obtain the permitted bend and twist conditions from the cable supplier and check them through the intended travel. For continuous rotation, determine whether a rotary service interface is needed instead of assuming that a free cable loop can accommodate unlimited turns.
Add the service movement envelope to the mechanical layout. Consider the cable at its least favorable position, not only in the centered installation photograph. Review assembly access and replacement access as well: a service can fit in operation yet be impossible to replace without dismantling the bearing support.
The outcome should be a controlled interface drawing showing the space reserved for services independently of the bearing seats.

The following values describe KAYDON K10008XP0 and J10008XP0, not certified LYDL performance.
| Catalog rating | Dynamic | Static |
|---|---|---|
| Radial | 6,570 N | 10,395 N |
| Axial | 10,052 N | 25,997 N |
| Moment | 266 N·m | 562 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 J10008XP0 reference, Kaydon lists 630 rpm at loads up to 20% of dynamic capacity, and 0.15 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 use is a rotating camera or inspection head with power and signal services routed through its center. The bearing supports the hub while the service arrangement must remain clear of the rotating parts. Select the open or sealed version in the context of that complete enclosure.
During prototype evaluation, monitor the head with services installed and during the full commanded travel. Compare the motion with the services in different permitted positions. If the measured behavior changes, investigate the routing and strain relief rather than immediately assigning the change to the bearing.
Use representative connectors and protective sleeves in the prototype. A temporary thin test cable may not reveal the clearance or stiffness problems introduced by the production harness. This example is a layout exercise and does not imply an electrical, optical or environmental certification.

Check the inner and outer boundaries of any sleeve that passes close to the bearing. Include sleeve eccentricity, permitted movement and the location of its retaining hardware in the tolerance review. A nominal radial gap does not establish clearance under every allowed assembly condition.
For PX10008UU, show the sealing region on the interface section so nearby components do not use it as a rubbing surface or an axial stop. For PX10008, identify how the exposed bearing is protected from debris released during cable installation or service.
Route services without using the bearing rings as an unintended guide or reaction point. If a harness is restrained to a neighboring component, describe that attachment on the assembly drawing. A build instruction should show the intended routing before the covers are fitted, with enough access for inspection.
Complete the clearance check after installing the production connectors and strain relief.
Use PX10008 — Open and PX10008UU — Double Sealed for LYDL purchasing. The corresponding KAYDON references are K10008XP0 and J10008XP0, 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.
Brand labels cannot define the service passage. INA / Schaeffler’s sealed CSXU050-2RS is a 127 × 146.05 × 12.7 mm example, not this 100 mm seat. NSK NBX identifies an inch-design four-point family, with DD denoting two-sided sealing. Check actual bore and section drawings when comparing suppliers.
An acceptance plan can compare the motion before and after the service package is fitted, using the same load and measurement method. Record where the harness is attached and its permitted freedom of movement. Inspect clearances at both travel limits and at any intermediate position where the route changes shape.
Keep bearing accuracy, assembled runout and camera or sensor performance as separate requirements. Each may be influenced by components outside the bearing. Identify the measurement reference surfaces so results from the component supplier and machine builder can be interpreted together.
Ask the quotation to identify the selected closure and any lubricant or internal-setting requirements needed for the proposed assembly.

Only if the complete design leaves that space available, which a conventional hub usually does not. Calculate the usable opening from the hub, sleeves, fasteners and connectors. The bearing bore must not be advertised as the finished service-passage diameter.
It does not close every route through the machine. Inspect the hub passage, connector openings and cover joints separately. Define the required environmental performance at assembly level, then decide how integral bearing seals contribute to that design.
Repeat the defined motion with the harness in its permitted positions while keeping load and drive settings constant. Check attachment points and bending behavior. A position-dependent service force can affect the assembled axis, so distinguish it from bearing runout or internal resistance.
Review its clearance against each approved bearing section before doing so. The common outer dimensions do not identify every face feature. Include sleeve location tolerances and any axial motion, and verify that no seal becomes a locating or contacting surface.
Supply a section with rotating and stationary components identified, the available installation space and the complete motion range. Add load cases, service-routing details and the chosen closure. This allows the bearing review to address the interface actually being built.
Compare PX10013 if the same 100 mm bore can accommodate a wider section. Review PX11008 when considering a 110 mm seat; a small change in bore still requires a new hub and interface check.
