6912 2rs Bearing Structural Features & Performance Benefits
Sealed Construction: The double rubber seals (2RS) effectively shield the bearing interior from dust, moisture, and other contaminants while retaining lubricant, significantly extending service intervals and enhancing reliability in harsh environments.
Load Capacity: With a dynamic radial load rating of 4545 lbf and static radial load rating of 3892 lbf, this bearing handles substantial radial loads efficiently. The deep groove raceway geometry also accommodates moderate axial loads in both directions.
Precision & Stability: Manufactured to ABEC-1 tolerance class with C0 radial internal clearance (0.008mm to 0.028mm), it ensures smooth operation and reduced vibration, contributing to overall system accuracy.
Material Quality: Chrome steel rings and balls provide high hardness and wear resistance, while the stainless steel cage offers corrosion resistance and ensures proper ball guidance at the limiting speed of 8,900 rpm.
