cylindrical roller bearingMain Character:It can endures radial charge and axis charge at the same time.It can work in the high rev. If contact angular is bigger, the endued-ability on axis side is higher. The ball bearing on high precision and high rev usually 15 contact angular. Under the effect of radial force, the contact angular would become larger.The single-row bearing can only endure axis charge on one direction. While enduring the radial charge, it will cause axis burthen. And it can only restrict the movement of axis or crust on one direction. If it is gemination-both installation and it makes bearing's outer circle face to face, that, it means that wide surface is up against wide surface and narrow surface is up against narrow one, it not only can avoid add-ons axis force, but also can restrict the axis and crust in the windage bound on the two directions.It usually uses inside track or outside track, and inside track and outside track can not be imparted. After heat-expanding, the outside track will assemble with inside-track, rolling body and holding frame. The contenting balls' quantity is larger than deep groove balls', and its rating charge is the most in the ball bearings. And it has strong rigidity and stable running. It can adjust radial windage making use of inside and outside circles. It is often used in pair and endured in pre-burthen to improve bearings' rigidity.
