The 6204 ZZ deep groove ball bearing is a reliable and widely used bearing solution designed for applications that require stable performance, low friction, and effective protection against solid contaminants. As a single-row deep groove ball bearing with double metal shields (ZZ), this bearing is ideal for applications operating in relatively clean environments where higher speed capability and long service life are essential.
The 6204 ZZ bearing is engineered to support high radial loads along with moderate axial loads in both directions, making it a versatile and cost-effective solution for a wide range of industrial and mechanical systems.
Precision Engineering and Shielded Bearing Design
The 6204 ZZ bearing is manufactured using precision-ground inner and outer rings combined with high-quality steel balls to ensure smooth rotation, reduced vibration, and quiet operation. Its deep groove raceway design provides excellent load distribution, minimizing internal stress and heat generation during operation.
Equipped with double metal shields on both sides, the bearing is protected against the ingress of dust and solid particles while allowing higher rotational speeds compared to sealed bearings. The non-contact shield design helps retain lubricant inside the bearing without increasing friction, resulting in efficient performance and extended service life.
Technical Specifications of 6204 ZZ Ball Bearing
The 6204 ZZ deep groove ball bearing has an inner diameter of 20 mm, an outer diameter of 47 mm, and a width of 14 mm. With an approximate weight of 0.11 kg, the bearing offers a compact yet durable structure suitable for light to medium-duty industrial applications.
In terms of load capacity, the bearing provides a dynamic load rating of 13 kN and a static load rating of 6.6 kN, allowing it to operate reliably under significant radial loads and moderate axial loads.
Regarding speed performance, the 6204 ZZ bearing can operate at speeds of up to 14,000 revolutions per minute when grease-lubricated and up to 17,000 revolutions per minute when oil-lubricated. The double metal shielded design enables higher speed capability compared to sealed bearings while maintaining effective contamination protection.
