Five-inch bore within a half-inch radial section

The KD050CP0 thin section bearing reference is an open Type C design measuring 127 × 152.4 × 12.7 mm. It uses a half-inch square section around a five-inch bore. Specify LYDL-D050 Type C together with KD050CP0 for a quotation, with the actual load case supplied when evaluating the reference capacities.

KD050CP0 thin section bearing dimensions

Parameter	Symbol	in	mm
Bore diameter	d	5	127
Outside diameter	D	6	152.4
Axial width	B	0.5	12.7
Radial section	(D − d) / 2	0.5	12.7

A six-inch outside diameter does not identify a six-inch shaft

For this bearing, the six-inch dimension belongs to the outer ring. The shaft interface is five inches. That distinction becomes important when several larger thin-section references are compared on a housing drawing or when a supplier receives only an outside-diameter measurement. The half-inch section consumes more radial and axial volume than the KA, KB and KC five-inch options. The reference load table may support an engineering comparison, but a larger catalog rating is not a substitute for verifying the support structure and actual reactions.

Kaydon KD050CP0 reference load ratings

Reference rating	lbf	kN (converted)
Dynamic radial — Kaydon method	1,964	8.736
Dynamic radial — ISO comparison	3,808	16.939
Static radial	3,760	16.725

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
LYDL	LYDL-D050 Type C	Supply inquiry identity
Kaydon	KD050CP0	Open radial-contact reference
Silverthin	SD050CP0	Same nominal size and contact family
INA / Schaeffler	CSCD050	CSC catalog radial-contact reference

KD050CP0, SD050CP0 and CSCD050 identify brand-specific references for the 5 × 6 × 0.5 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 radial-support study with occasional impact

A mechanism that experiences occasional impact needs a description of the peak force and how it reaches the bearing. Include clearance take-up, force offset and the condition of the surrounding supports. An average steady load does not represent a short shock event. The KD050CP0 envelope can be considered during that study, without asserting impact qualification or a safe working payload. Separate the static assessment from the rotating fatigue calculation. The resulting supply requirement should state the relevant operating and inspection conditions.

Related sizes and installation envelopes

Reference	Bore d (in)	Outside D (in)	Width B (in)
KD050CP0	5	6	0.5
KB050CP0	5	5.625	0.3125
KC050CP0	5	5.75	0.375
KD060CP0	6	7	0.5

KB050CP0 and KC050CP0 offer smaller sections at the five-inch bore. KD060CP0 preserves the half-inch section but increases both nominal diameters by one inch. Check which housing and shaft interfaces can change before ranking candidates by reference capacity. Compare the installation dimensions of KB050CP0, KC050CP0, KD060CP0. Explore the open Type C size table and radial-contact bearing category. For another contact arrangement, see the KD050XP0 four-point contact reference.

Do not equate static capacity with permissible machine weight

Static reference capacity depends on the manufacturer’s stated assumptions and is not a lifting or equipment rating. A suspended mass can generate different bearing reactions depending on its offset, acceleration and support arrangement. Review the complete force system before interpreting the number commercially. Check shoulders, corner clearances and axial retention against the drawing for the supplied configuration. The bearing’s 12.7 mm width is one component of the axial stack. A thicker section does not remove the need for appropriate mounting force and clean seating surfaces.

Inspection, handling and packing

Protect the half-inch ring from contact with heavy machine parts during transport. Use separation and restraint that prevent both surface damage and concentrated deformation. Request identification and any agreed inspection records to remain linked to the individual order items.

Questions about this model

Is KD050CP0 the six-inch-bore bearing in this group?

No. It has a five-inch bore and six-inch outside diameter. KD060CP0 is the six-inch-bore reference and requires a seven-inch outer envelope.

Can its static radial capacity be converted directly to payload kilograms?

That would not establish an allowable machine payload. Force direction, offsets, acceleration, shock and the support arrangement determine bearing reactions. Static catalog capacity is not a certified equipment working-load limit.

What is needed to assess an occasional impact?

Describe the peak force or impact event, its location, duration where known and how the structure transmits it. Include any free movement before contact; average process load alone does not describe the event.

Does the half-inch section include external seals?

The nominal 12.7 mm section describes the open bearing. Any separate sealing arrangement and its retention require additional review and space in the machine layout.

Why keep a separate dynamic check for a shock-loaded mechanism?

A static or peak-load assessment does not cover fatigue from repeated rotation. The rotating duty and the occasional peak must each be evaluated using the appropriate method and configuration data.
