If your bearings have a metal shield on them, you do not have to remove the shield to clean them. If your bearings have a rubber seal then you should remove the seals according to the instructions below. Doing this achieves maximum performance. Using our Clean Touch bearing cleaner, or any standard degreaser, fill a small glass cup or vial sufficiently to submerge your bearings completely. Place the shielded bearings, or the sealed bearings with the seals removed, into the solution. You can also use a small ultrasonic cleaner if you have one.

Soaking time may vary depending on whether you have grease or oil in your bearings or if you are using an ultrasonic, but a few hours of soaking should be more than enough. You can now either blow your bearings dry with compressed air or allow them to air dry for up to 24 hours. For maximum performance the bearings should be thoroughly dry. At this point you can spin test the bearing on an awl or any sharp pointed tool like our Utility Tool. If the bearings do not spin to your satisfaction you may need to repeat the cleaning and drying process. Learn More »

Angular Contact Bearings
Angular contact bearings are designed such that there is an angle between the races and the balls when the bearing is in operation. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings are typically assembled with a thrust load or preload....Learn More »
