Thus, except for Spindle Broaching types of operations, they (Angular Contact Ball Bearins) have fairly good axial load capabilities and lower overall friction. The question really is, What kind of axial load do you need? |
| Roger B:
Both options are better than the original bearings. If I remember correctly the angular contact bearings don't require the spacers to be modified. |

Did this on my CJ18A "taper rollers" did not fit the shaft difference in dimensions damaged the shaft, plus seals are a problem this cost me a new shaft, so went with angular contact bearings Looking back i think the original bearings where just as good |

Hi all Perhaps these PDF File Is Useful for you. Thanks to Arceurotade.co.uk I have no connection with this company only know it from reading of it on other forums. Please be aware that Taper Roller Bearings are 17.25 mm wide and the Angular Contact Bearing and the Ball Bearing are 16 mm wide. I Converted an X2 Mill Drill to Taper Rollers and Poly Vee Belt Drive With no problems. Eric |
