Overview
Nachi 1303 Self-aligning ball bearing
Self-Aligning Ball Bearing with cylindrical bore and normal clearance
The Nachi 1303 is a small double-row self-aligning ball bearing with a 17 mm bore, 47 mm outside diameter and 14 mm width. Two rows of balls run against a single spherical raceway in the outer ring, so the inner ring, ball set and cage can swivel freely inside the outer ring. The bearing therefore shrugs off shaft deflection and housings that are not perfectly in line, a common situation in agricultural machinery, textile lines and long fabricated shafts. Of all rolling bearing types this one has the lowest friction, so it runs cool even at speed. Cylindrical bore, sheet steel cage, normal CN clearance, rated -30 to +150 degrees C.
