4309 bearing is suitable for high or even very high speed operation, and are very durable, without frequent maintenance.4309 bearing has small friction coefficient, high limit speed, varied size range and form, and is used in precision instrument, low noise motor, automobile, motorcycle and general machinery industries.
4309 bearing have simple structure and are easy to achieve higher manufacturing accuracy compared with other types, so they are easy to be mass-produced in series and have lower manufacturing cost, and are very popular in use.In addition to the basic type, there are various variant structures.

4309 bearing installation method: force fit: bearing inner ring and shaft tight fit, outer ring and bearing hole is a loose fit, press the bearing to be pressed on the shaft are available, and then put the shaft together with the bearing load bearing hole, when pressed on the bearing inner ring end face, cushion the assembling casing made of a soft metal material.4309 bearing outer ring and bearing hole tight fit, inner ring and the shaft is a loose fit, 4309 bearing can be pressed into the bearing hole first, then assembling casing diameter should be slightly less than the diameter of a hole.If the bearing ring is tightly matched with the shaft and the seat hole, the inner ring and the outer ring should be pressed into the shaft and the seat hole at the same time, and the structure of the assembly sleeve should be able to tighten the end face of the inner ring and the outer ring of the bearing at the same time.
