ZZ Slewing Bearing selects materials for strength, wear resistance, and long-term durability:

Slewing ring: 42CrMo, 50Mn, C45N, 40CrNiMo, C48E.

Special forging spare parts: carburized/hardened steels for gear teeth (20CrMnTi, 18CrNiMo7‑6).

Corrosion resistant: SS 304, 316L, duplex stainless steel.

Surface treatments: heat treatment, quenching, carburizing, induction hardening, and surface coating(Four-Layer Packing, Strong Anti-Rust Oil, Black Oxide Treatment, Jet Black Paint Finish, Hot-Dip Galvanizing (CGL), Electro-Galvanizing (EGL), Hot-Dip Galvanizing + Paint Finish)

Correct installation with flat surfaces.

Proper lubrication using grease.

Avoid overloading or shock loads over capacity.

Monitor operating conditions regularly to prevent debris entry.

Typical factors observed by ZZ engineers:

  • Insufficient or incorrect lubrication.
  • (dust, metal particles) in raceways.
  • Rolling element or track damage.
  • Uneven mounting surfaces or misalignment.
  • Incorrect bolt torque(below grade 8.8) or preloading.
