Features of Outer Ball Cylindrical Roller Bearing Outer Ball Cylindrical Roller Bearings are mainly characterized by low section height and high load bearing capacity. The main bearing has a compact structure and low price, and the bearing seat hole cannot be used as the raceway of the needle roller cage assembly. Bearings and bearing housings must be installed together. If the box shoulder and axial snap ring positioning can be omitted, the bearing housing bore can be very simple and economical.

The outer ring of the lubricating oil hole in the outer ball cylindrical roller bearing. According to user needs, all single punched peripheral needle roller bearings whose shaft diameter is greater than or equal to F7mm must be equipped with an outer ring with lubricating oil holes (model suffix AS1). Sealed outer ball cylindrical roller bearings, in the sealed space limitation, can not be installed due to occasions, provide open or closed sealed outer ball cylindrical roller bearings. This type of bearing friction type oil sealing equipment is filled with polyurethane or synthetic rubber and lithium-based grease with good anti-rust performance, and the working temperature is -20~100C.
