The 6210 ZZ deep groove ball bearing is a robust and reliable bearing solution designed for industrial applications that require stable operation, low friction, and effective protection against solid contaminants. As a single-row deep groove ball bearing with double metal shields (ZZ), this bearing is well suited for applications operating in relatively clean environments where higher rotational efficiency and long service life are essential.
The 6210 ZZ bearing is designed to support high radial loads along with moderate axial loads in both directions, making it a versatile and dependable choice for a wide range of industrial machinery and mechanical systems.
Precision Engineering and Shielded Bearing Design
The 6210 ZZ bearing is manufactured with precision-ground inner and outer rings and high-quality steel balls to ensure smooth rotation, low friction, and reduced vibration. Its deep groove raceway geometry allows for even load distribution across the rolling elements, which helps minimize wear, internal stress, and heat generation during operation.
The bearing is equipped with double metal shields on both sides, which protect the internal components from dust and solid particles while retaining lubricant inside the bearing. Since the metal shields are non-contact, they allow higher operating speeds compared to sealed bearings, making the 6210 ZZ bearing ideal for applications requiring efficient rotation and reliable contamination protection.
Technical Specifications of 6210 ZZ Ball Bearing
The 6210 ZZ deep groove ball bearing has an inner diameter of 50 mm, an outer diameter of 90 mm, and a width of 20 mm. With an approximate weight of 0.46 kg, it provides a strong and durable structure suitable for medium to heavy-duty industrial applications.
In terms of load capacity, the bearing offers a dynamic load rating of 35.7 kN and a static load rating of 23.2 kN, enabling it to operate reliably under substantial radial loads while maintaining stable axial load support.
Regarding speed performance, the 6210 ZZ bearing can operate at speeds of up to 6,900 revolutions per minute when grease-lubricated and up to 8,300 revolutions per minute when oil-lubricated. The double metal shielded design allows for higher speed capability compared to sealed bearings while ensuring effective protection against contamination.
