High-speed rolling mill bearings are available in four rows of tapered roller bearings and double row cylindrical roller bearings. Normally, four-row tapered roller bearings are used in rough and medium-sized rolling mills; double-row cylindrical roller bearings are used in finishing mills; horizontal rolling mills and The plumb mill uses the same type of bearing.
Whether it is a four-row tapered roller bearing; it is still a double-row cylindrical roller bearing; its basic layout is similar to that of a conventional rolling mill bearing; however, the depiction of each part fully considers the problem of smoothness and heat dissipation; that is, the inner ring, the outer ring, and the inner ring Rings (for four-row tapered roller bearings), cages, rollers (for double row cylindrical roller bearings) have many slots, holes, etc. This way; grooves, holes make smooth, heat dissipation channels and bearings The seat and the passage on the roll form a firm smooth and heat-dissipating system; coupled with outstanding sealing equipment; the bearing can operate stably in high-speed and high-pressure conditions.
Although the high-strength rolling mill bearings supplied by various manufacturers have different personalities; they all have one thing in common; that is, the inner bearing is relatively thicker than the standard bearing; the outer ring is relatively thin.
