Self aligning ball bearing is divided into open self aligning ball bearing, KA retainer bearing, double sealed self aligning ball bearing and single sealed self aligning ball bearing these four categories.
Open self aligning ball bearing is one of the most common self aligning ball bearing, also called open bearing plate bearing, both bearing itself without sealing roller, there are several layers of nylon self aligning protection ball bearing sealing ring, the sealing performance is good, the bearing sealing type self aligning ball to make an unnecessary move. Bearing easy to install according to the actual situation before their master grease filling capacity for self bearing aligning ball, self aligning ball bearing self open aligning ball bearing seal cost also has a certain price advantage than the belt, roller conveyor and to improve market competitiveness.
KA bearing retainer is used in mine transport machinery, mining supplies must be coal card, nylon retainer bearing fit the national security certificate standard, effectively avoid bearing rolling caused by static electricity, solid nylon is characterized by the stick strength and elasticity have good links with the appearance of the nylon steel has excellent lubricating sliding function. With the rolling body stick smooth surface touch, rarely occur in the conflict, thus bearing heating and wear is very low, low density data means to frame is very small, adhere to the operation characteristics of nylon frame in the lack of lubricant under the condition of great promise, bearing continued to operate for a period of time, not soon locking and further damage.
Self aligning ball bearing double seal for sealing requirements relatively high or roller bearing grease injection conditions of production enterprises is not perfect, the bearing at the factory before injection plus good oil bearing self sealing dustproof cover, iron sealing, glue sealing of cap sealing dustproof; single sealed bearing iron seal and rubber seal. The axial bearing capacity of self aligning ball bearing will directly affect the service life of the roller and affect the working efficiency of the whole conveying system.
