Cylindrical Roller Radial Bearings - Four-Row Timken 510RX2461

Описание

Timken’s four-row cylindrical roller bearings are designed for the rigors of daily use in applications where moderate and high speeds, high radial loads, elevated temperatures and debris are constant challenges. Designed with well-balanced cross sections, these bearings provide high-radial-load capacity within the bearing envelope. The radial internal clearance (RIC) for the bearing assembly must be included when ordering either a) the complete assembly or b) with the inner-ring set. It is advisable to order the inner-ring set independent of the outer ring set when the final grind of the inner-ring O.D. is accomplished after mounting on the roll neck. The RX bearings are four-row construction, having two single flangedouter races and rib rings for roller spacing. This allowsfor complete disassembly for inspection. The RX style is usuallypreferred in bearings above 400 mm bore. Both brass and pin-type cages are available in this bearing style.Most inners are two-piece assemblies. Two outer rings with three rib rings. Two inner rings. Four pin-type steel cages. RX-1 – with lubrication grooves and holes on outer rings. RX-9 – with oil-mist nozzles and O-rings in outer rings. RX-11 – with lubrication grooves, holes and O-rings on outer rings. Specifications Bore d 510 mm Static Load Rating Co 27280000 N Dynamic Load Rating C11 12680000 N Bearing Dimensions O.D.
