Taper Roller Bearing 30307
30307 tapered roller bearings belong to the metric 30000 series, with an inner diameter of 35.000 mm and an outer diameter of 80.000 mm, and a thickness of 22.750 mm. They have ordinary tolerances and also provide P6X, P6, P5, P4, and P2 tolerance products, all of which are in line with GB307.1. Clearance is only available after installation and can be determined after adjustment with another bearing oriented in the opposite direction. Because of its outer diameter of D≤650mm, the steel plate stamping cage is used, and the rear code of the cage is not marked.
This type of bearing has a wide range of applications and is mainly used in transmission devices, construction machinery, vibrating screens, machine tools, automobiles, metallurgy, mining, petroleum, machinery, electric power, motors, fans, railways, and other industries.
