6312‑2Z/C3 is single‑row deep groove ball bearing fitted with double metal shields and C3 enlarged internal clearance.
It handles radial loads as well as bidirectional axial loads for general industrial rotating assemblies.
Pre‑greased at factory, double‑side metal shields block dust and dirt to cut daily maintenance work.
C3 clearance fits working conditions with higher operating temperature and minor shaft thermal expansion.
Made of standard bearing steel, it delivers steady running performance for motor and transmission equipment.

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.
