Standard Kaydon Reali-Slim® bearings are manufactured to Kaydon Precision Class 1 and the specifications listed in the table below.
Kaydon Reali-Slim® bearings can be optimized for special requirements and ordered with non-standard materials, sizes, tolerances, specifications, and features as well as custom packaging and lubrication options.
Kaydon also have ISO Class 7 facilities for applications requiring clean room assembly. Standard commercial options include changes in diametral clearance, preloading, lubricants, packaging, etching of high points, tagging bearings with actual dimensions as requested, separators, duplexing, data sheets, acceptance testing, and more.

| Diametral clearance & contact angle | ||
| Type A bearing | Diametral clearance for 30° contact angle in single unmounted bearing under light axial gaging load. Wide range of preload or running clearance for matched sets. | |
| Type C bearing | Sufficient diametral clearance to provide small amount of running clearance after installation with recommended fits. | |
| Type X bearing | Gothic arch form for two 30° contact angles under light radial gaging load. Sufficient diametral clearance to provide clearance after installation with recommended fits. | |
| Separator design | ||
| R & G types A bearings |
Circular ring, circular pockets, self retained | |
| P & L types C, X bearings |
Circular ring, snapped over balls for retention | |
| Other | ||
| Quality control | Kaydon Quality Control procedures have been approved by major aerospace industries and agencies of the U.S. Government | ISO 9001, AS 9100 |
| Identification | Marked on bearing O.D.: CAGE code, "Kaydon"®, part number and date code | MIL-STD-130 |
| Cleaning | Multiple cycle immersion and agitation in solvents and/or aqueous cleaners | |
| Preservative | Preservative oil | |
| Packaging | Typically, smaller bearings are heat-sealed in a plastic bag and boxed; larger bearings are "tire-wrapped." | |
