Eight-inch aperture and thin-ring support continuity

The KA080CP0 thin section bearing reference has an eight-inch bore, with a 203.2 mm inside diameter, 215.9 mm outside diameter and 6.35 mm width. LYDL-A080 Type C is the corresponding inquiry identity. The large opening combined with a quarter-inch section makes the support arrangement a central part of the engineering review.

KA080CP0 thin section bearing dimensions

Parameter	Symbol	in	mm
Bore diameter	d	8	203.2
Outside diameter	D	8.5	215.9
Axial width	B	0.25	6.35
Radial section	(D − d) / 2	0.25	6.35

The mounting ring is part of the support system

The bearing has the same nominal section as smaller KA sizes, despite its larger diameter. Review how the housing supports that circumference, including interruptions, thin wall regions and fastening locations. A nominally correct bore does not by itself show that the installed ring will retain an appropriate shape under load. If the bearing sits in a lightweight frame, include the frame material and attachment geometry in the drawing package. Its deformation and temperature response may matter to the running fit. The catalog envelope does not establish an allowable housing deflection or guarantee assembled stiffness.

Kaydon KA080CP0 reference load ratings

Reference rating	lbf	kN (converted)
Dynamic radial — Kaydon method	851	3.785
Dynamic radial — ISO comparison	1,647	7.326
Static radial	2,500	11.121

Source: Kaydon official model table, referenced below. These are Kaydon reference capacities, not verified LYDL supply ratings. Dynamic values use a one-million-revolution L10 basis; the ISO column is a comparison rating calculated per ISO 281:1990. Static values assume rigid shaft and housing support. Ratings are not additive or simultaneous permissible loads. Conversion: 1 lbf = 0.0044482216152605 kN; displayed kN values are rounded.

Brand designations for this nominal envelope

Brand	Designation	Scope

Kaydon	KA080CP0	Open radial-contact reference
Silverthin	SA080CP0	Same nominal size and contact family
INA / Schaeffler	CSCA080	CSC catalog radial-contact reference

KA080CP0, SA080CP0 and CSCA080 identify brand-specific references for the 8 × 8.5 × 0.25 in radial-contact envelope. INA / Schaeffler uses CSC for the Conrad radial family; its following letter identifies the section. Compare the complete specification before interchange. Brand names remain with their owners; this LYDL offer does not imply brand authorization. Catalog references do not guarantee current availability.

Large central openings in inspection equipment

A rotary inspection assembly can need a broad central opening while leaving little axial room for support. The KA080CP0 envelope is one candidate to assess for that packaging problem. Identify the payload center, cable routing and any drive force applied away from the bearing plane before deciding that a radial-contact ring is appropriate. When the instrument measures position during motion, specify the measurement axis and operating state. A bearing catalog reference cannot substitute for a complete error budget covering the frame, shaft, encoder and mounting interfaces. No specific inspection-machine installation is claimed here.

KA070CP0 and KA100CP0 change aperture size within the quarter-inch section. KB080CP0 preserves the eight-inch shaft interface but increases outside diameter to 219.075 mm and width to 7.9375 mm. These choices address different space constraints. Compare the installation dimensions of KA070CP0, KA100CP0, KB080CP0. Explore the open Type C size table and radial-contact bearing category. For another contact arrangement, see the KA080XP0 four-point contact reference.

Roundness and uniform seating around the circumference

Use a measurement plan suitable for a flexible ring and the approved drawing. A single diameter reading may miss an out-of-round condition in the support. During mounting, check for localized interference, trapped contamination or a cover that loads only a few points. Where the assembly includes dissimilar materials, provide temperature ranges for both stationary and rotating parts. Thermal effects should be considered when selecting the fit and operating clearance, particularly if the mechanism sees warm-up cycles or changes in ambient conditions.

Inspection, handling and packing

Support the eight-inch ring so it cannot flex against neighboring cargo. Protective layers should prevent metal-to-metal rubbing without imposing concentrated bending. Specify storage conditions and corrosion protection suited to the interval before installation.

Questions about this model

Why does a large KA080CP0 ring need attention to housing roundness?

A thin ring depends on its mounting support. Localized distortion or an out-of-round seat can influence the installed geometry. Use the agreed support and measurement conditions rather than relying only on a single nominal diameter.

Can I infer stiffness from its 203.2 mm bore?

No. Bore size and section describe geometry, while assembly stiffness depends on bearing configuration, supports and loading. Provide the required displacement or stiffness target with the actual force and moment conditions.

Is KA080CP0 the same as a nominal 200 mm bearing?

Its bore is 203.2 mm, a 3.2 mm difference. The inch reference and a 200 mm design require different mating interfaces even if their catalog descriptions both sound like large thin-section bearings.

What should be checked in an aluminum mounting frame?

Provide frame geometry and its temperature range relative to the bearing rings. Evaluate support deformation and differential expansion as part of fit and clearance selection; no single universal interference value is implied by this reference.

Can KB080CP0 retain the current axial cover position?

Not automatically. KB080CP0 is 1.5875 mm wider than KA080CP0 and also has a larger outside diameter. Review both the outer seat and cover stack before substituting the thicker section.
