The KC050CP0 thin section bearing reference combines a five-inch bore with a three-eighths-inch section for open radial contact. Its nominal dimensions are 127 × 146.05 × 9.525 mm. LYDL-C050 Type C is the inquiry identity used here; include KC050CP0 and the intended duty when requesting a quotation or a drawing for the mounting review.

| Parameter | Symbol | in | mm |
|---|---|---|---|
| Bore diameter | d | 5 | 127 |
| Outside diameter | D | 5.75 | 146.05 |
| Axial width | B | 0.375 | 9.525 |
| Radial section | (D − d) / 2 | 0.375 | 9.525 |
A housing-mounted ring may experience a load that moves around its circumference, even when the housing itself does not rotate. Identify whether the force direction stays fixed relative to each ring. That relationship belongs in a fit assessment alongside the load magnitude and operating temperature.
The 9.525 mm section distinguishes this bearing from the five-inch KA and KB references. Its outer seat is 146.05 mm in nominal diameter, and the bearing depth remains separate from the thickness of any locating shoulder. An envelope sketch should include adjacent rotating parts and their clearances.

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 | Designation | Scope |
|---|---|---|
| LYDL | LYDL-C050 Type C | Supply inquiry identity |
| Kaydon | KC050CP0 | Open radial-contact reference |
| Silverthin | SC050CP0 | Same nominal size and contact family |
| INA / Schaeffler | CSCC050 | CSC catalog radial-contact reference |
KC050CP0, SC050CP0 and CSCC050 identify brand-specific references for the 5 × 5.75 × 0.375 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.
Send KC050CP0, quantity and the application to begin a quotation. Where an existing assembly must be preserved, identify its fixed interfaces and include the available drawing. A complete analysis is not required to start the commercial inquiry.

An eccentric drive or rotating imbalance can impose a changing radial force. A constant catalog load number does not describe the time history of that force, and the starting, steady-running and stopping conditions can differ. State the speed range and load cycle when asking for selection support.
This reference may be considered during a packaging study, but no suitability for a particular eccentric mechanism is implied. The assembly's balance, support stiffness and vibration requirements need their own review. If significant thrust or moment is present, assess the appropriate contact arrangement before selecting on nominal diameter.
| Reference | Bore d (in) | Outside D (in) | Width B (in) |
|---|---|---|---|
| KC050CP0 | 5 | 5.75 | 0.375 |
| KB050CP0 | 5 | 5.625 | 0.3125 |
| KD050CP0 | 5 | 6 | 0.5 |
| KC060CP0 | 6 | 6.75 | 0.375 |
KB050CP0 reduces the five-inch section and KD050CP0 enlarges it. KC060CP0 instead increases the bore while retaining the KC section. These alternatives should be compared against the constraints of the housing and shaft, not treated as visually similar replacements.
Compare the installation dimensions of KB050CP0, KD050CP0, KC060CP0.
Explore the open Type C size table and radial-contact bearing category. For another contact arrangement, see the KC050XP0 four-point contact reference.
Specify whether acceptance testing is performed with a drive attached, under a representative radial load or on a separate fixture. These conditions can produce different observations. Include the test temperature and measurement position when a running torque or accuracy requirement matters.
The bearing's reference designation does not authorize transferring another brand's cage, lubricant or clearance directly into the LYDL order. Agree these details in the drawing or supply specification, then use the same revision during receipt inspection and installation.
For a precision assembly, preserve the bearing's identity through storage and inspection. Keep the ring protected from moisture and handling contamination, and use separation that prevents its edges from striking other components during transit.
No. A rotating imbalance or eccentric force may move the load around a stationary ring. Describe the load direction relative to each ring so the fit can be assessed for the actual mechanism.
Keep 146.05 mm as the nominal conversion from 5.75 inches. A machining tolerance must be specified separately; rounding the nominal value can change the intended interface.
Provide speed, eccentric geometry, mass distribution and the force cycle, including start and stop conditions. Also describe thrust, overhang and support spacing so the bearing reactions can be evaluated.
It will not reproduce a specified loaded running condition. Agree the fixture, radial load, temperature and speed if torque is an acceptance requirement; a hand check can only provide a limited observation.
The outside diameter grows to 152.4 mm and width to 12.7 mm. KC050CP0 uses a 146.05 mm outer diameter and 9.525 mm width, so both the seat and retention depth differ.
Include “LYDL-C050 Type C, KC050CP0 reference,” quantity and delivery destination. Add the required load case, speed and installation drawing when available. Ask for a drawing review if the shaft, housing or retention geometry must match an existing assembly.
