• Inch series.
• Heavy duty.
• Standard cage.

About Shell Type Needle Roller Bearing

• Shell Type Needle Roller Bearings are lightweight with the lowest sectional height among needle roller bearings with outer ring, because they employ a shell type outer ring made from a thin special-steel plate that is accurately drawn, carburized, and quenched.
• Since these bearings are press-fitted into the housing, no axial positioning fixtures are required.
• They are ideal for use in mass-produced articles that require economy.

About Structure and Features

• Shell Type Needle Roller Bearings are lightweight bearings with large load ratings.
• They employ a shell-type outer ring made from a thin special-steel plate that is accurately drawn, carburized, and quenched, thus providing the lowest sectional height among the needle roller bearings.
• There are two types of bearings available in this series; the caged type and the full complement type.
• The appropriate type can be selected according to the operating conditions.
• The caged type has a structure in which the needle rollers are accurately guided by the cage and thrust rings.
• It is useful for applications at high-speed rotation.
• The full complement type needle roller bearing, on the other hand, is suitable for heavy-load applications at low-speed rotation.
• Since these bearings are press-fitted into the housing, no fixtures for axial positioning are needed.
• They are ideal for use in mass-produced articles that require the economy and have a wide variety of applications.
