K20013XP0 is the KAYDON reference for LYDL PX20013, an open metric Type X bearing sized 200 × 226 × 13 mm.
For this ring size, purchasing and quality teams should agree how the bearing is supported and measured before comparing inspection reports. Free-state component checks and mounted-machine results answer different questions. Define the required records, identification and handling method alongside the technical specification.

K20013XP0 is the comparison reference for LYDL PX20013 open, a 200 × 226 × 13 mm four-point contact thin section bearing. The quoted product is LYDL and should be ordered against an agreed configuration and drawing revision.
This page focuses on the handoff between the supplier, receiving inspection and machine assembly. A useful acceptance plan explains what will be measured, how the ring will be supported and which records remain with the part after unpacking.
The confirmed purchasing identity here is PX20013 open, referenced to K20013XP0. No sealed KAYDON counterpart was verified in the official literature reviewed. Keep any request for an integral-seal design outside the released part number until its specification is approved.

See the LYDL metric Type X listing for the catalog grouping. Confirm the actual material, internal setting and lubrication on the supply drawing.
A diameter or runout value is meaningful only with a defined method and acceptance criterion. Identify the datum surfaces, support arrangement and measuring force where these affect the result. State whether a characteristic is evaluated on the unmounted bearing or after installation in a specified fixture.
Ask the supplier and receiving team to review the same drawing and inspection plan. If their equipment or support arrangements differ, establish how the methods will be compared before a disputed shipment occurs. Do not assume that two measurements with the same label were obtained under equivalent conditions.
Keep dimensional acceptance separate from functional behavior in the machine. A component report cannot establish the runout of the complete hub, and a machine measurement cannot isolate a bearing dimension without an appropriate method.
The inspection agreement should also state how unusual results are recorded and reviewed. Retaining the actual readings and setup information is more useful than a pass stamp without supporting context.

The following values describe KAYDON K20013XP0, not certified LYDL performance.
| Catalog rating | Dynamic | Static |
|---|---|---|
| Radial | 18,319 N | 31,695 N |
| Axial | 28,910 N | 79,238 N |
| Moment | 1,464 N·m | 3,375 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 builder producing a rotary module in batches may need the same PX20013 configuration over several deliveries. The practical challenge is to preserve the approved combination of bearing characteristics, documentation and assembly conditions when purchasing schedules change.
Start the first-article review with a clearly identified sample and released mating-part drawings. Record the checks performed by the supplier and those performed after assembly. Use the resulting acceptance record to define future orders, including any special lubricant, internal setting or marking requirement.
This example is a procurement and inspection workflow, not a claim that LYDL has already qualified the bearing for a particular machine. The actual acceptance limits must come from the customer's design requirements and the agreed supply specification.
Specify how the bearing is supported while it is unpacked, inspected and transferred. Use a handling method that protects the ring faces and keeps contamination away from the open raceway. Do not let removal from the protective pack erase the connection between the part and its identification.
Prepare a clean temporary location for the bearing if inspection and assembly are separated in time. Keep the specified protection in place until the next controlled operation. Confirm any requirements for corrosion protection or storage with the supplier rather than assigning an unsupported shelf-life claim.
During mounting, use the approved seating and retention procedure. Record the transition from unmounted inspection to mounted functional checks so a later comparison does not mix the two conditions. If an assembly is removed and rebuilt, identify which results belong to each build.
Return the accepted records to the quality system with the component identification intact.
Use PX20013 — Open for LYDL purchasing. The verified KAYDON reference is K20013XP0; 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.
Keep reference-brand examples out of the released part identity. INA / Schaeffler CSXU050-2RS demonstrates a sealed-model designation; NSK NBX and DD denote its inch-design four-point family and two-sided sealing. These are terminology comparisons only. They supply neither a matching 200 × 226 × 13 mm model nor an inspection specification for LYDL.
State which inspection results must accompany each delivery and which are required only for first-article approval. Specify the identification needed on the product or package and the documents used to link a delivery to its production record.
If sampling is used, agree the sampling plan and the response to an out-of-limit result. Do not describe a sampled inspection as proof that every characteristic of every unit was measured. If a particular measurement is required on every bearing, make that requirement explicit in the quotation.
Purchasing should also identify changes that require notification or renewed approval. A repeat order should reproduce the qualified configuration, not merely the nominal 200 mm bore.
First compare the drawing revision, support, datum scheme, measuring force and temperature conditions relevant to the method. Differences in setup can affect comparability. Preserve the readings and investigate with the agreed inspection procedure before deciding which result governs acceptance.
Use the condition appropriate to the specified characteristic and state it explicitly. Component dimensions and complete-assembly behavior are different requirements. Where both matter, define two tests rather than treating one result as a substitute for the other.
Maintain the agreed protection and identification during each transfer, using a suitable support method. Avoid exposing the raceway unnecessarily or resting functional faces on uncontrolled surfaces. Confirm the delivered preservation condition and any preparation needed before working lubrication is applied.
First-article records qualify a specified configuration and process under agreed conditions. Routine records support acceptance of later deliveries according to the inspection plan. State which tests recur and which changes invalidate the original approval.
A certificate can document agreed component checks, but it does not demonstrate every behavior of the completed machine. Keep the component release and mounted functional acceptance separate, with their own methods and limits. Link both to the approved configuration.
PX20008 keeps the nominal 200 mm bore with a thinner section and different housing envelope. PX15013 provides a smaller-bore 13 mm-section comparison centered on cyclic-duty requirements.
