Key Performance Features

01. Non-Contact Metal Shielding (-ZZ)

Features dual cold-rolled steel shields that provide physical protection against particulates. Because the shields do not touch the inner ring, they eliminate the friction drag found in rubber seals, allowing for significantly higher top speeds and cooler operation.

02. Optimized Precision Geometry

The deep, high-precision raceway grooves are ground to exacting tolerances to minimize vibration and noise. This design also allows the 6212-ZZ to support moderate axial loads in both directions in addition to heavy radial loads.

03. High-Strength Chrome Steel (GCr15)

Manufactured from premium GCr15 Chrome Steel (SAE 52100), the raceways and rolling elements are heat-treated to ensure maximum wear resistance. This high-purity material extends the rolling fatigue life of the bearing under continuous radial loads.
