The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Engine rocker arm assemblies may include ring-like roller members to engage a camshaft and drive displacement of a valve. The roller members are typically supported on a shaft and bearing members, such as needle bearings may be located between the shaft and the roller member. The inclusion of the needle bearings may reduce a radial thickness of the roller member due to packaging constrains. Removal of the needle bearings may create lubrication concerns for the interface between the shaft and the roller member.
