The 6012 ZZ deep groove ball bearing is a single-row radial ball bearing designed for smooth rotation, high-speed capability, and reliable performance in industrial and automotive applications. Featuring double metal shields (ZZ), this bearing provides effective protection against dust and light contamination while maintaining low friction and stable operation.
The 6012 ZZ bearing is capable of supporting high radial loads along with moderate axial loads in both directions, making it a versatile solution for a wide range of mechanical systems.

Precision Engineering and Double Shielded Construction
The 6012 ZZ bearing is manufactured from high-grade bearing steel with precision-ground raceways and accurately sized steel balls to ensure smooth motion, minimal vibration, and reduced operating noise.
Its deep groove raceway geometry enables efficient load distribution across the rolling elements, minimizing wear and heat generation during continuous operation.
The double metal shields (ZZ) are installed on both sides of the bearing to retain lubricant while protecting internal components from dust and debris. This design reduces maintenance requirements and enhances service life, especially in moderately contaminated environments.

Technical Specifications of 6012 ZZ Ball Bearing
The 6012 ZZ deep groove ball bearing has an inner diameter of 60 mm, an outer diameter of 95 mm, and a width (B) of 18 mm. The approximate weight of the bearing is 0.38 kg, providing a compact yet durable structure for industrial use.
In terms of load capacity, the bearing offers a dynamic load rating (C) of 29.4 kN and a static load rating (C₀) of 21.5 kN, allowing it to operate reliably under substantial radial loads while supporting moderate axial forces in both directions.
Regarding speed performance, the limiting speed reaches 6,900 rpm in grease lubrication and up to 7,500 rpm in oil lubrication. Due to the presence of metal shields, operating speeds remain high while providing improved internal protection compared to open-type bearings.
