Standard Bushings

Sibo’s standard is a standard bushing with SIBO tolerances (Ø Outside u6 – Ø Inside C8) that undergo casehardening and tempering treatment with case hardening depth of 0.8-1 mm and Hardness HRC 58-62.

When the bush undergoes this special thermal treatment to fully enhance its characteristics, it is suitable for use in workplaces requiring excellent resistance to wear and tear and seizing. The smoothness obtained with this cycle reduces the friction factor and consequently makes the bush more efficient.
