marine crane bearing Cross roller bearings

1, deep groove ball bearing

Continuous groove type 1.1 structure of deep groove ball bearings on each ring has a cross-section of approximately spherical perimeter 1/3 raceway. It is mainly used to bear radial load, also can withstand the axial load.

1.2 in the bearing radial marine crane bearing‍ clearance increases, with the nature of angular contact ball bearing, the axial load bearing two directions alternating.

1.3 small friction, high speed.

1.4 has the advantages of simple structure, low manufacturing cost, easy to manufacture high precision.

1.5 general methods of stamping cage diameter greater than 200mm, slewing bearing‍ the bearing or high-speed operation, the use of the car business entity retainer. Variant structure of deep groove ball bearing as many as 60.
