NTN 4-Row Cylindrical Roller Bearings 4R15201๏ผ
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.
