KOYO inch tapered roller bearing ST4276A Koyo ST4276 Tapered Roller Bearing 4302074 transmission parts
brief description of tapered roller bearings:
Tapered roller bearings are designed to take combined heavy radial loads and heavy thrust loads in one direction while operating at moderate speeds. The bearings shown are single row with a cone and cup (inner and outer rings) and a pressed steel retainer. Metric tapers feature a simplified part number for a complete bearing. Inch tapers require a part number for the cup and one for the cone. The difference between the metric and inch tapers is only in the dimensions of measure for the bearings.
