C1 clearance bearings that were floppy from side to side are probably past their best. All the bearings in the gearbox and Apron were replaced though. resulted in a pair of front bearings that had no visible marks on the races and ran smoothly. I thought that the spindle bearings felt a bit 'gritty' when I turned the spindle by hand (before I'd got anywhere near putting power on it).Ī very thorough cleaning with degreaser, powerful water jets, brushes, de-watering oil etc. I still have a HLV-H that needs a bunch of work to get up & running, but I don't know the condition of its spindle bearings yet. There are two more bearing sets on eBay that might work, but one is British & the other German & I couldn't locate catalogs for them. It is a long page so I will have to do it in stages & stitch them together.

Here is a link to the SKF page (I couldn't find a download option) that describes their system:Īs soon as I get the chance, I am going to use my photo program to do a screen save on this page for my own reference.

The 15 degree contact is identified by the CD right after the 7011 and in this case, the ACD identifies the 25 degree contact angle. I especially appreciate having the cross reference info.Īs far as the "A" in this SFK system, it actually goes w/the P4 designation (ABEC 7) and means that it has a runout accuracy better than a P4. RichThanks so much Rich for your time and any trouble. So the 50 to 200 preload goes to 65 to 270 poundsĪnd max speed drops from 24K RPM to 22 K RPM

The "KR" code means a Conrad style normally ( deep grove), but found no listingĢ5 degree bearings usually have a 30 % greater preload than 15 degree bearings

I found a MRC 111 KS bearing reference as a 55 x 90 x 18 and was a extra light series ball bearingĪlso found a MRC 111 M and 111S, but they are 55 x 100 x 12 ! They all are 55 x 90 x 18 and have a basic dynamic load of 8600 pounds ~ The SKF is the same as a Barden 111H or a Fafnir 2MM9111WIDUL Normally, a C means 15 degrees and a E means 25 The SKF number 7011CD/P4ADGA is a good bearing For spindlesĭon't know what the "A" means in the eBay item. MRC 111 KRD B ABEC 7 (all marked on the outer race)īesides being a different manufacturer, the MRCs #s are older and even their numbering system has been updated.īesides being a different manufacturer, the MRCs #s are older and even their numbering system has been updated.Well Jim I have some info. This makes sense to my twisted mind too, so I tend to agree with your feeling that I will not likely run into a problem.Ī problem I have is cross-referencing the bearing #s. So, I get from this that the larger angle will take a larger thrust load, but a smaller radial load.

When a radial load is applied, the smaller the contact angle, the smaller the load acting on the rolling element, thus resulting in reduced load at the contact point.” Load at the contact point, and its consequential deformation, is reduced thus resulting in longer life. “Therefore, the larger the contact angle, the smaller the load acting on the rolling element.

I think I might have found an answer in some NSK information. Thanks Rich for responding and for your offer.
