Brass cage Spherical roller bearing
Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.
The symmetrical barrel rollers freely align themselves to the concave outer ring raceway. As a result, shaft deflections and mislignments of the bearing seats are compensated.
Features
a, low speed, impact resistance, vibration
b, with self-aligning function, namely the inner ring relative to the axis of a larger outer ring axis is tilted (usually in less than 3 degrees) still operate normally
c, mainly bear large radial load
d, but also can withstand a small axial load
Self-guiding rollers and a floating guide ring between the two rows of rollers
Self-guiding rollers reduce friction and frictional heat. A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
