Clearance automatic compensation of high temperature environment---
Due to foot the bearing inner and outer rings spiral spring, temperature change, inner and outer diameters of the axial and radial autostretch, which can ensure that the operating clearance under high temperature environment is essentially the same, and not lead to a stuck.
Resistance to shock---
This kind of inner and outer rings of bearing for spiral springs, high temperature quenching, tempering, and plastic, with strong rigidity and stability.
