NTN 4-Row Cylindrical Roller Bearings 4R2628

NTN Bearing

Since the rollers of the cylindrical roller bearings make line contact with the raceways, these bearings can support heavy radial loads and are suitable for high speed operation.

Assembly and disassembly are comparatively easy even if the inner or outer ring requires a shrink fit, as the bearing is a separation type.

Cylindrical roller bearings are classified as single row, double row and four row type, according to how many rollers are used.

NTN 4-Row Cylindrical Roller Bearings 4R2628:

1) The bearings are mainly used in the roll necks of steel rolling mills and designed so that the load rating is maximized in the allowable space of the roll neck part.
2) The cage types include a comb type cage and a pin type cage (that uses hollow rollers). The pin type cage maximizes the number of rollers for high load capacity.
3) Carburizing (case hardened) steel is used in some cases to prevent inner ring cracks and to improve shock resistance.
4) Consult us for bearing internal clearance and fits to be used for back-up rolls of rolling mills.
5) There are many varieties of these bearings, including bearings which are sealed, have tapered bores, designed for high speed, have creep prevention, etc. Contact us for further
details.
