What is the surface treatment of the centralizer?

The surface treatment is spray-paint to protect against corrosion and wear.

Can the axle shear stresses be managed effectively?

Yes, the roller/axle relationship ensures axle shear stresses remain within elastic limits, preventing permanent deformation.
