Cold pier machine

ZBO CC structure spherical roller bearing is our main product. It is characterized by the use of steel plate

stamping cage,reinforced symmetrical rolling body and independent spacer, which can be common

with CA structure design in general. Compared with CA structure, CC structure adopts high quality

carbon steel plate stamping parts, the tensile strength of the cage has been greatly improved,meanwhile,

because CC structure design occupies less space inside the bearing than CA structure design, so the

number of rolling elements is increased and the shape size of rolling elements is changed, thus the radial

bearing capacity can be improved to a certain extent. In the limit speed, the CA type and CC type structure

design are comparable to each other.

In the international market, spherical roller bearings of CC structure are widely used for their structural

advantages,and their service life is significantly better than that of CA structure spherical roller bearings in

specific use environments.

The series of bearings for cold pier machine adopt targeted internal structure design, special material and

heat treatment process, with high bearing capacity, stable and durable precision, good lubrication

performance, impact resistance, long life, etc., which can replace imported products. This series of

products can also be used in heavy load and impact environments such as pipe rolling mills and crushers.
