Product Description

Product description
This type of bearing is used to bear heavier radial-axial combined loads with limit rotational speeds higher. The bearings are mainly applied to the construction parts that limit axial displacement of the axis or housing in double directions.
The bearing is used with four row cylindrical roller bearings limiting the axial motion of roll in rolling mill the axial load capactiy is heavier than four-point contact ball ebearings incomparison with paiy mounted in back-to-back, face-to-face arvangements single row angular contact ball bearings units, the axial clearance of the bearing doesn't need adjustment, these bearings can be mounted with ease and there can be two types: two half-outer-rings and two half-inner-rings according to the installation need of customers.
