Q1: What do 2Z and C3 stand for?
A1: 2Z is double metal dust shields, C3 is enlarged clearance for high‑speed high‑temperature use.
Q2: Are 2Z/C3 bearings pre‑greased?
A2: Yes, factory pre‑lubricated for fast installation and less maintenance.
Q3: Why choose C3 clearance?
A3: It compensates shaft thermal expansion to prevent bearing jamming.
Q4: Is 2Z bearing waterproof?
A4: No, only dust‑proof. Choose 2RS for wet working conditions.
Q5: What loads can 2Z/C3 take?
A5: Mainly radial loads, plus moderate bidirectional axial loads.
