KOYO 7044B bearing

220x340x56

Angular contact ball bearing. Concept. Angular c ontact b all b earings c an bear radial load and axial load at the same time. The bearing can work at a higher speed. The larger the contact angle, the higher the axial bearing capacity. I t is usually take 15 degrees contact angle at the h igh precision and high speed.C ontact angle become bigger as given an axial force.
