KB080CP0 Thin Section Bearing Reference – Open Type C

Eight-inch radial support with a 7.9375 mm section

The KB080CP0 thin section bearing reference specifies an eight-inch bore, 219.075 mm outside diameter and 7.9375 mm width for open Type C contact. LYDL-B080 Type C is the corresponding inquiry identity. This size combines a broad center opening with the KB section and should be reviewed with the complete mounting and thermal arrangement.

KB080CP0 thin section bearing dimensions

Distinguish section selection from preload selection

Choosing a KB section instead of KA changes the bearing envelope. It does not by itself select internal clearance, establish preload or define a running torque. Those properties depend on the actual configuration and installation, so they belong in separate fields of the engineering specification. The nominal eight-inch bore equals 203.2 mm. At that diameter, the support material, temperature difference and mounting condition should be described clearly. A generic fit copied from a different bearing size may fail to represent the intended thin-ring assembly.

Kaydon KB080CP0 reference load ratings

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

KB080CP0, SB080CP0 and CSCB080 identify brand-specific references for the 8 × 8.625 × 0.3125 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.

A broad hollow hub exposed to warm-up cycles

A motor-adjacent hollow hub may warm differently from its surrounding housing. Provide a realistic description of startup, normal operation and shutdown conditions. The bearing’s open construction also requires a lubricant and contamination plan appropriate to that environment. This is a potential application study rather than a supplied motor-bearing specification. No universal speed or temperature limit is claimed from the model code. The objective is to evaluate the actual hub geometry, force directions and operating clearance together.

Related sizes and installation envelopes

KA080CP0 reduces section at the same bore; KB060CP0 reduces bore at the same section. KA100CP0 gives a larger aperture with a smaller section. These alternatives show why bore size and section thickness should be separate selection variables. Compare the installation dimensions of KA080CP0, KB060CP0, KA100CP0. Explore the open Type C size table and radial-contact bearing category. For another contact arrangement, see the KB080XP0 four-point contact reference.

Use operating conditions to define the running check

If running behavior is critical after warm-up, include a representative thermal condition in the acceptance discussion. Document which components rotate, how they are retained and where temperature is measured. A cold free-running observation alone cannot define hot installed behavior. Review cover clearance and service routing around the 219.075 mm outer envelope. Avoid using a cover to impose an uncalculated axial condition on the ring. The approved drawing should clarify location, support and the intended internal setting.

Inspection, handling and packing

Provide support that keeps this eight-inch ring separated from heavy housings or drive parts. Labels should preserve the KB section and open radial identity through storage. Confirm any preservation and cleaning requirements before the receiving team removes the protective coating.

Questions about this model

Does selecting KB080CP0 automatically add preload over KA080CP0?

No. The change is primarily to the nominal section and installation envelope. Internal clearance or preload must be specified and reviewed separately for the actual supplied bearing and mounting conditions.

Can I use the cold running torque as the hot acceptance value?

Only if the agreed test and application justify that relationship. Warm-up can change fits, lubrication behavior and surrounding geometry. State the relevant temperature condition when defining the running requirement.

Which diameter must the housing accommodate?

The nominal outside diameter is 8.625 inches, or 219.075 mm. The eight-inch figure refers to the bore, and the complete housing body requires space beyond the bearing seat.

Is this a motor bearing solely because it has a hollow-center format?

No. Suitability depends on speed, forces, thermal conditions, electrical and environmental requirements where applicable, and the selected configuration. The geometry alone does not establish a motor application qualification.

What is different about KA100CP0 as a design alternative?

KA100CP0 has a larger 254 mm bore but a smaller 6.35 mm section. It changes both aperture and section relative to KB080CP0, so it represents a different layout rather than a direct substitute.
