Questions buyers ask

Why would a pivot bolt contain both an axial and a radial passage?

They can form part of a deliberate route from a lubrication point to a working interface. Their need depends on the bearing arrangement and service method. Review connectivity, remaining section and cleaning access together. Do not add passages solely because another pivot design uses them, or infer that they bypass sealed-bearing instructions.

Can a grease groove replace the specified bearing lubrication method?

No. Identify the actual bearing or bushing arrangement and its intended service method. A groove may be useful in one design but unnecessary or unsuitable in another. Do not override sealed-bearing or component instructions with a generic drilled lubrication path.

What needs checking at cross-drilled passage intersections?

Consider connectivity, inaccessible edges, remaining debris and the intended flow path, using methods appropriate to the geometry. Also retain the structural design requirements. A clean external hole opening does not establish the condition of every internal intersection.

Does a larger groove always distribute lubricant better?

Not universally. Its usefulness depends on the working interface and route, and changing it can affect contact and remaining section. Evaluate the actual design and service objective rather than increasing groove size as a general remedy for wear or noise.

Can a similar catalog feature be copied into a new component?

Use it as a design reference, not as automatic approval. Check the actual mating geometry, loads, operating motion and assembly method. Similar-looking knurls, slots or eccentric features can serve different purposes and require different controls.
