Spherical roller bearings, whose high load carrying capacity and ability to accommodate misalignment help you obtain low maintenance costs and long bearing service life. QIBR spherical roller bearings could be used for many applications, including wind turbine main shafts, continuous casters, vibratory applications and high-speed applications.
The latest international design, it uses symmetrical spherical rollers, two pieces of quenched steel stamping cage, inner ring without ribs and with a middle retaining ring guided by the cage.
The middle retaining ring close to the outer ring can improve the lubrication of the contact between the end face of the roller and the retaining ring.
Its function is to reduce bearing friction, help guide the roller in the non-load area, and assist the roller to enter the load area while rolling The length of the sub is increased, so the rated load has been greatly improved. Usually the rated load can be increased by 20% to 35%.
The overall brass processing cage, the inner ring has no intermediate flange, the end face has two small flanges, and the rollers are symmetrical. Has a certain self-lubricating function. The roller occupies a small space, which limits the overall size and quantity of the roller body, and its carrying capacity is limited. The cage has its own movable guide ring.
CA is slightly stronger than CC in terms of lubricity and load-carrying capacity. Since the purchase cost of CC is higher than the cost of CA, CA spherical roller bearings can be used instead of CC if there is no special design requirement.
The rollers are symmetrical, the inner ring has no middle ribs, and no end ribs, the cage is divided, the material is a stamped steel frame cage, and a movable intermediate ring is designed between the roller and the roller.
It can effectively reduce the internal friction of the bearing, can effectively assist the rolling elements in the non-stressed area to enter the load area correctly, and also increase the limit speed of the bearing. Can withstand greater axial load capacity than CA structure design, CC structure should be used more frequently under heavy load and high speed working conditions.
