Three-and-a-half-inch shaft inside a four-inch outer envelope

The KA035CP0 thin section bearing reference combines an 88.9 mm bore with a 101.6 mm outside diameter and 6.35 mm width. This open Type C reference is identified for quotation as LYDL-A035 Type C. It is useful to evaluate when the four-inch constraint belongs to the outer bearing envelope rather than the shaft.

KA035CP0 thin section bearing dimensions

Parameter	Symbol	in	mm
Bore diameter	d	3.5	88.9
Outside diameter	D	4	101.6
Axial width	B	0.25	6.35
Radial section	(D − d) / 2	0.25	6.35

Interpreting a four-inch housing constraint correctly

For KA035CP0, four inches describes the bearing outside diameter. KA040CP0 uses four inches for the bore and therefore needs a larger housing. This distinction is particularly important when a buyer receives an old sketch labeled only four-inch thin bearing. The nominal bearing envelope does not define the outside diameter of the housing body. A wall, flange or fastener pattern lies beyond the outer seat. If the entire housing must fit within four inches, a bearing whose own outside diameter is four inches leaves no radial space for that conventional wall arrangement.

Kaydon KA035CP0 reference load ratings

Reference rating	lbf	kN (converted)
Dynamic radial — Kaydon method	530	2.358
Dynamic radial — ISO comparison	1,230	5.471
Static radial	1,140	5.071

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-A035 Type C	Supply inquiry identity
Kaydon	KA035CP0	Open radial-contact reference
Silverthin	SA035CP0	Same nominal size and contact family
INA / Schaeffler	CSCA035	CSC catalog radial-contact reference

KA035CP0, SA035CP0 and CSCA035 identify brand-specific references for the 3.5 × 4 × 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.

Compact radial guidance around a hollow sleeve

A hollow sleeve can be assessed against the 88.9 mm nominal bore while its support fits a 101.6 mm bearing envelope. Define the sleeve’s external load and the location of its other support. If the sleeve carries an offset arm, include the resulting moment rather than describing only the arm’s weight. The example does not establish a universal permissible arm length or payload. These depend on the complete support geometry and the selected configuration. A short technical sketch can resolve whether a radial-contact design is the appropriate starting point.

Related sizes and installation envelopes

Reference	Bore d (in)	Outside D (in)	Width B (in)
KA035CP0	3.5	4	0.25
KA025CP0	2.5	3	0.25
KA030CP0	3	3.5	0.25
KA040CP0	4	4.5	0.25

Moving from KA030CP0 to KA035CP0 adds half an inch to both diameters; moving onward to KA040CP0 adds another half inch. The nominal 6.35 mm width stays constant throughout, while each model needs its own shaft and housing interfaces. Compare the installation dimensions of KA025CP0, KA030CP0, KA040CP0. Explore the open Type C size table and radial-contact bearing category. For another contact arrangement, see the KA035XP0 four-point contact reference.

Provide a removal route as well as an insertion route

A compact installation should allow maintenance without prying against the open raceway or driving through the rolling contacts. Review access behind the ring and the sequence for releasing retainers before the housing design is finalized. This is especially relevant when the available outer envelope is tightly constrained. Inspection should identify the approved bore, outer seat and width tolerances. If a measurement is taken on a removed bearing, record its support condition so it can be compared meaningfully with the specified method. Do not convert a free-ring measurement into an assumed housing-fit correction.

Inspection, handling and packing

Keep the three-and-a-half-inch bore identity visible during receiving. A four-inch outside-diameter ring may otherwise be confused with a four-inch-bore item in a mixed shipment. Use individual wrapping and restraint to protect its narrow section from tool or component contact.

Questions about this model

Can a complete four-inch-diameter housing contain KA035CP0?

The bearing itself has a four-inch outside diameter. A conventional surrounding wall would require additional radial space, so the complete housing limit must be reviewed rather than equated to the bearing envelope.

How is KA035CP0 different from a four-inch-bore model?

Its bore is 3.5 inches, or 88.9 mm. KA040CP0 has a four-inch bore and a 4.5-inch outside diameter. These are different shaft and housing sizes despite the shared four-inch dimension.

What information is needed for an offset sleeve arm?

Include the applied force, arm length, bearing positions and direction of motion. Those determine the support reactions and moment demand; arm weight alone is not a complete bearing load case.

Should maintenance access be included in the first layout?

Yes. Show how retainers are released and how the ring can be removed without loading through the balls or damaging the raceway. A compact envelope can otherwise leave no practical removal route.

Does an 88.9 mm bore specify the running clearance?

No. Bore diameter describes the shaft interface. Internal running clearance is a different property and must be selected with fits, temperature and the intended operating conditions.
