What are they?
Single row deep groove ball bearings are the most widely used type of roller bearing. They feature a simple, non-separable design with deep raceway grooves, allowing them to support both radial and axial loads in either direction.
What are they used for?
Due to their versatility and high-speed capabilities, they are primarily used in electric motors, industrial pumps, gearboxes, fans, agricultural machinery, and automotive components where reliable rotation is critical.
What are their main advantages?
They offer exceptionally low friction, smooth operation, and high-speed capacity. Furthermore, their simple design requires minimal maintenance, making them highly cost-effective for large-scale industrial applications.
Product Overview: Structural Excellence
Single row deep groove ball bearings are engineered with a remarkably simple yet versatile structure. The deep, uninterrupted raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and certain axial loads in both directions simultaneously.
This optimal internal geometry results in exceptionally low friction, which translates to smooth operation, minimal heat generation, and the ability to achieve very high rotational speeds. Because they are robust in operation and require little maintenance, they have become the foundational component of modern industrial machinery.
Whether deployed in high-speed electric motors or heavy-duty industrial gearboxes, their easy installation and reliable performance make them the preferred choice for procurement teams and design engineers worldwide.

Available Configurations
We supply different configurations of single row deep groove ball bearings according to your specific application environment and customer requirements.
Open Type
Designed without seals or shields. Ideal for applications where the bearing is enclosed within a continuously lubricated housing, allowing for maximum speed capabilities.
Shielded (Z / ZZ)
Equipped with metal shields on one (Z) or both sides (ZZ). Provides non-contact protection against larger dust particles while retaining factory-filled grease.
Sealed (RS / 2RS)
Features rubber contact seals on one (RS) or both sides (2RS). Offers superior protection against moisture and fine contaminants, perfect for exposed environments.
Custom Configurations Available
Beyond standard types, we offer chrome steel, stainless steel options, custom internal clearance levels, OEM laser marking, and customized industrial packaging tailored to your brand.
Common Series Designations
6000 Series
Extra Light Series. Positioned for applications with limited space and lighter loads. Offers excellent dimensional flexibility and is commonly used in small motors and precision instruments.
6200 Series
Light Series. The most popular and balanced series. Ideal for moderate radial loads and speeds. Widely utilized in general industrial machinery, automotive parts, and appliances.
