Cool... I've been searching for those sizes!!!
The above seal mentioned by davemccoull is listed by CR in 2 different seal types...
23442 is a single lipped 60X80X10 (ID X OD X W)
The second listing is 23438 which is a double lipped seal 60X80X10.
If you are installing these in pairs DO NOT PUT BOTH IN THE SAME DIRECTION!!! Install the first seal using PN 23438 OR PN 23442 and install the second (outer) seal using PN 23442 ONLY installing it BACKWARDS with a little grease between them. This will allow the outer seal to act as a dust wipe and prevent the shaft from being eaten up!
I would never recommend using PN 23438 in a 2 seal application, being that it is double lipped you end up with 4 seal surfaces ganged up together and you can not face them in opposite directions as needed, the lips will crush and bind... Shaft wear, shaft wear, shaft wear!!!
If you wish to install a single seal rather than using the above mentioned seals in pairs the closest part number (found to date) is a CR 23443 60X80X13MM which is a single lip seal.
Keep posting the PN's and or sizes to things as you find them... I have an XML file that is growing by the day with civilian cross reference part numbers and suppliers.
