Single row angular contact ball bearing

Single Row Angular Contact Ball Bearing

In applications requiring extreme precision, axial preloading springs may not be suitable. For effective preload application through a spring, the bearing being preloaded should be able to move freely on the shaft or within the housing if the preload is applied to the outer race. This necessitates a minimum of radial play, which could compromise the system's accuracy.

I concur with the first recommendation from israelkk regarding a duplex preloaded pair. If SKF does not recognize the benefits of this setup, they are overlooking an essential aspect. The optimum arrangement would feature the duplex preloaded pair at one end of the shaft and a cylindrical roller bearing with slight radial preload on the opposite end, although achieving this is quite challenging.

Alternatively, utilizing two single row bearings, which you have already acquired, is also an option. You can design the mounting structure for one of the bearings at the shaft's end to be radially rigid while allowing for some axial flexibility or “springiness.” This way, by slightly deflecting the structure during installation, it will apply a load to the bearings once it tries to return to its neutral position.

Considering Replacing Lathe Spindle Bearings with Angular Contact Bearings

When it comes to upgrading my lathe spindle bearings, I have several options. Finding ISO 492 Class 4 tapered roller bearings is difficult, yet many manufacturers offer equivalent outer and inner diameter angular contact bearings. Any loss in thickness can be compensated by using ground shims or by modifying the head stock spindle retaining system. To determine the best approach, I will need to disassemble the head stock, as the bearings’ shoulders do not perfectly align. The load-bearing capacities of these bearings are almost equivalent, though I remain in the speculation stage of this consideration.

Is it worthwhile to replace the spindle bearings in my lathe? I wonder whether the accuracy of the other sliding components utilizes the benefits of ABEC-7 bearings. This is the very machine where I learned to scrape dovetail ways, and both the compound and cross slide function without any wiggle. If my scraping of the bedways is successful, I could essentially create a tool room lathe, albeit without the rigid castings.
