    Four Row Sealed Full Complement Cylindrical Roller Bearings

    The cylindrical roller is in line contact with the raceway, and the radial load capacity is large. It is not only suitable for bearing heavy load and impact load, but also suitable for high-speed rotation. CRB raceways and rolling element geometric shapes have been improved and designed to have higher load-bearing capacity. The new structural design of ribs and roller end faces not only improves the axial load-bearing capacity of the bearing, but also improves the roller end faces. The lubrication condition of the contact area with the rib improves the performance of the bearing. This type of bearing is mainly used in medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, reduction gears, loading and unloading handling machinery, and various industrial machinery.

    Tolerance
    Sinofou produces single-row, double-row and four-row CRB with tolerances of up to Class 4, and also produces double-row cylindrical roller bearings with special tolerances of Class SP and UP for machine tool spindles.
    Radial Clearance

    The standard products of Sinofou single-row CRB have basic radial clearance, and also can have 3, 4 groups of clearance.

    The standard products of Sinofou double-row CRB have 1 group of clearance, cylindrical bore bearings also can have 2, 3 groups of clearance, and tapered bore bearings also can have 2 groups of clearance.

    The standard products of Sinofou four-row CRB have 3 groups of clearance, and other clearance products are also available.

    Bearings with radial clearance greater than or less than the standard value can also be produced according to user requirements.

    Cage
    Single-row CRB mostly use vehicle solid cages, stamping cages, nylon cages, etc. Double-row cylindrical roller bearings mostly use turned brass cage, sometimes can also use nylon cages. Four-row cylindrical roller bearings mainly use turned brass cage, and for larger size, turned solid pillar cages shall be used.
