Spherical roller bearings have two rows of barrel shaped symmetrical rollers, related the adjective `spherical'. typically held in a brass or steel cage without fixed middle block.a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis .Therefore, spherical roller bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, The center point of the sphere in the outer ring raceway is at the roller bearing axis. modified line contact between rollers and internal & external ring to achieve maximum loading capacity. mainly bear radial load.
Since sliding cannot be eliminated in the contacts between the cage and other bearing parts, the cage itself is the first component to be affected when lubrication becomes inadequate. Compare with Steel Cage Spherical Roller Bearing, 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.
FEATURE:
The design of Spherical Roller Bearing allows the roller rows in Roller Bearing to run at different speeds, thereby enabling the bearing to absorb high levels of linear deviation. Spherical roller bearings have high radial load capacity, which is especially suitable for work under the heavy load, high shock or vibration load and misaligned loads, but can't afford to pure axial load.
TYPES:
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.
APPLICATION:
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.

The machine is a kind of electric tensile tester which adopts the motor to drive ball screw to move fixture. Place the fixture with sample between the upper and lower fixture, use a given speed to pull sample upward by upper fixture. Load cell above upper fixture will sense tensile strength, and convert the strength into voltage sign and output to the display screen. And the strength value will be displayed automatically on micro computer or host computer.
Â
