K10013XP0 is the reference for LYDL PX10013, an open four-point contact bearing with 100 × 126 × 13 mm boundary dimensions. It is a 13 mm-section option for a 100 mm bearing seat.
Changing from a 100 mm-bore, 8 mm-section layout requires a new housing and axial-stack review. The unchanged bore does not make the wider bearing a direct replacement. Compare support geometry and application requirements before selecting the revised arrangement.
Provide the existing and proposed assembly sections to request a PX10013 drawing and quotation.
K10013XP0 is the KAYDON Type X reference associated with LYDL PX10013 open. The LYDL product has a nominal 100 × 126 × 13 mm envelope and belongs to the 13 mm metric section group.
This page addresses a common redesign decision: retaining a 100 mm shaft seat while considering a wider bearing section. The change affects more than the part number, so the review should include the housing, locating shoulders, cover and complete axial stack.
For this 13 mm section, the checked official sources identify PX10013 and K10013XP0 as open. A sealed redesign needs its own confirmed designation and drawing. Do not create a J-prefixed reference by analogy with the 8 mm sealed family.

See the LYDL metric Type X listing for the catalog grouping. Confirm the actual material, internal setting and lubrication on the supply drawing.
Compared with PX10008 at 100 × 116 × 8 mm, PX10013 retains the nominal bore but increases the outside diameter by 10 mm and width by 5 mm. The radial section grows from 8 to 13 mm. These are envelope differences, not an installation instruction or a prediction of assembled stiffness.
Check whether the surrounding housing has room for the revised seat and whether nearby fasteners or passages would be affected. A larger bore in the housing can reduce material where a bolt or process interface already constrains the design. Show those features on the section supplied for review.
Next, follow the axial dimension chain from the machine datum to the working component. Decide where the additional width will be accommodated. Moving a cover alone may shift a coupling, encoder target or workpiece plane if the locating strategy is not kept consistent.
Release a revised assembly drawing that identifies all affected parts rather than treating the bearing as an isolated substitution.

The following values describe KAYDON K10013XP0, not certified LYDL performance.
| Catalog rating | Dynamic | Static |
|---|---|---|
| Radial | 12,543 N | 16,485 N |
| Axial | 18,691 N | 41,198 N |
| Moment | 532 N·m | 931 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.
The open reference table does not provide a model-specific speed limit here. Request the permitted operating conditions for the LYDL lubricant, internal setting and mounting arrangement; do not borrow a sealed model's speed figure.
A machine builder may want to retain an existing 100 mm shaft interface while changing the bearing arrangement in a compact rotary module. PX10013 can be evaluated as one candidate, provided that the available radial and axial spaces are checked with the required loads and operating behavior.
Begin with the function that motivates the redesign. If the problem is measured movement at a tool, define the allowed movement and the test load before selecting a new section. If the problem is life or a changed duty cycle, provide the relevant load history. A wider section should answer a stated engineering requirement.
Build the prototype with the revised housing and retention parts. Results obtained by temporarily spacing the old cover away from the assembly may not represent the final support arrangement.
A common shaft diameter does not establish that the existing shoulder is suitable for a new bearing. Compare its contact area, corner relief and axial location with the approved LYDL drawing. Identify which face controls the working position and which components provide retention.
Review the coupling and any sensing hardware that follows the shaft axially. A nominal 5 mm width increase can create a different interface problem depending on whether the bearing is located from its front face, rear face or another datum. Record the actual stack instead of assuming where the added width will appear.
The revised open arrangement also needs a workable lubrication and protection plan. Confirm that the new cover and housing do not block an intended access route or create a debris pocket near the bearing.
After assembly, verify the functional position of the rotating component against the machine datum, not only the seating of the bearing itself.
Use PX10013 — Open for LYDL purchasing. The verified KAYDON reference is K10013XP0; no sealed counterpart is assigned.
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.
Use dimensions when comparing an alternative section. INA / Schaeffler CSXU050-2RS measures 127 × 146.05 × 12.7 mm, illustrating why a similar width does not make it a 100 × 126 × 13 mm replacement. NSK’s NBX/DD terminology belongs to its inch-design four-point range. Compare complete interfaces, not rounded dimensions.
Use the same functional test to compare the previous and revised module where that comparison is meaningful. Keep the applied loads and measurement locations consistent, and document any other changes made at the same time. Otherwise an improvement cannot be attributed reliably to one design decision.
Request the LYDL characteristics needed for selection, including internal setting and the applicable load-rating basis. Reference-brand values are comparison data and do not replace the specification of the supplied bearing.
Keep the original and revised drawings under separate revisions. Identify any spare parts that are no longer compatible so maintenance personnel cannot mix an old retainer with the new bearing arrangement.
Their nominal outside diameters and widths differ. Review the housing seat, adjacent wall thickness and complete axial stack before substitution. Retaining a 100 mm bore preserves only one boundary dimension; it does not preserve the whole mounting interface.
No. Define where and under what load the unwanted movement occurs. Housing flexibility, fits, retention and other components can affect the result. Evaluate the revised assembly against a measured requirement rather than inferring accuracy from section size alone.
That depends on the assembly datum scheme. Trace the dimension chain to the working component and determine which locating faces can move. Check adjacent couplings, sensors and covers before choosing a revised stack.
No. PX11008 has a 110 mm bore and 8 mm width, while PX10013 has a 100 mm bore and 13 mm width. The shared outside diameter does not establish shaft compatibility, axial location or equivalent performance.
Tie the trial to a released drawing revision and a stated functional requirement. Record the bearing configuration, changed mating parts and test conditions. Purchasing can then order the approved arrangement without relying on a vague instruction to supply a stronger bearing.
The PX10008 / PX10008UU group provides the 100 mm-bore, 8 mm-section comparison. PX11008 is included to distinguish its shared 126 mm outside diameter from a genuinely matching installation.
