Made in America
Built To Last
Our heavy-duty roller bearing
wall thickness provides the maximum strength that you can rely on. All Harland Sharp Roller Bearings are hand assembled. Each assembled contains 27 needle bearings. These assemblies are knurled to achieve a precision press fit. In addition, they are heat treated and black oxidized to achieve maximum strength and durability.
We begin with a selection of 9 different 2024-T3511 high quality aluminum extrusions designed specifically for us. These are then machined in-house to ensure a perfect fitting rocker arm every time. Harland Sharp has and always will be committed to sourcing USA materials and resources. We are proud to say that all components, materials and machining is performed right here in our Ohio facilities.
All rocker arm bodies and steel components are machined at
our facility. Quality control is
maintained by our expert machinists. Nothing we deliver
has been made offshore.
Harland Sharp's pins are larger,
offering increased strength, and knurled to eliminate spinning. Centerless ground journals are counter bored and induction
annealed for maximum strength.
The centerless ground, heat treated end is riveted to prevent them backing out of position.
