Thornton mechanical lab surface grinder | The Hobby-Machinist

Surface grinders live in a world of metal grit and grinding wheel dust, which must be kept out of the bearings, or they will rapidly get damaged. Make sure you have some kind of sealing system that works properly, no missing parts or aftermarket wannabe sealing, everything in the bearing area tight and spotless when it goes back together.

Ball Bearing Types & Applications | SPB-USA, LLC

Ball Bearing. Types & Applications. Ball bearings are simple but powerful components that minimize friction in rotational applications ranging from industrial machinery to office equipment. Spherical ball bearings have only minimal contact with their containing races, allowing them to transfer radial or axial loads with rapid, fluid motion.

TECHNICAL INFORMATION

Both ball and roller thrust bearing require a minimum axial load to ensure a proper arrangement of balls/rollers along each raceway. In the case of ball thrust bearings operated at higher speeds, centrifugal forces and gyroscopic moments can have detrimental influence on the balls, i.e. sliding movements between the raceways and balls.

What are the best methods for preload in a bearing system ...

If preload is used primarily to protect the bearing from the damage caused by external vibrations when stationary, then greater preload is required and k = 0,02 should be used. Spring loading is also a common method of applying preload to angular contact ball bearings in high-speed grinding spindles.
