Conveyor drum pulley bearing is rolling element bearing used in conveyor system. Usually use spherical roller bearing and self-aligning ball bearing in conveyor drum pulley etc. which plays a role of reducing the friction among the components. Bearings support the rotating shaft and hence the pulley. The bearings are housed in 'plummer blocks' which enable the mass of the pulley assembly plus the belt tension forces to be transmitted to the pulley supporting structure.
Bearings used for conveyor pulleys are generally spherical roller bearings, chosen for their radial and axial load supporting characteristics. The bearings are self-aligning relative to their raceways, which means that the bearings can be 'misaligned' relative to the shaft and plummer blocks, to a certain degree. In practical terms this implies that the bending of the shaft under loaded conditions as well as minor misalignment of the pulley support structure, can be accommodated by the bearing.
Due to customers` requirements, XKTE can offer different structures of spherical roller bearing, such as steel sheet metal frame structure(C type), brass solid cage structure(CA type/M type)
CC, CA Spherical roller bearings are special bearings, because the energy consumption of such bearings is relatively low, just toughness more advantages. CA, CC Spherical roller bearings can operate freely in high-speed machinery, as well as high rigidity Low-friction precision work in the popular, but also has high bearing capacity so much loved by the majority of users.
Both the dynamic load rating and rating life equations contain no difference regarding cage design and material (brass or steel)
CC Spherical roller bearings equipped with steel cages and operating in conditions of poor lubrication, may lead to adhesive wear and smearing. The hard steel contaminants that may appear, as well as the indentations that may form on raceways and rolling elements, act as locations for surface fatigue
brass cages have a much higher resistance to adhesive bonding and, for this reason, even in harsh conditions, when lubrication is insufficient, they enable bearings to attain the design rating life.
Some spherical roller bearing variants may include perforated outer ring and oil groove features in their design to facilitate easier lubrication and further extending their longevity. with the suffix W33 or H.
Self-aligning ball bearing for conveyor drum pulley.
Main products are 1308-1316
Spherical roller bearing are available with heavy duty rollers and cages that are suitable for extreme demand harsh applications such as vibratory screens. Mining Conveyor Machine, and mining bulk conveyor pulley. In this sort of aggressive operational environment, the spherical roller bearing is the only type that delivers acceptable service life. generally have a longer life span than other bearing types.
