625-2RS Ball Bearings High Speed 5mm Width Miniature Bearings For Electric Motors Wheels Pool Pumps Spinners

The Single Row 625 2RS Ball Bearing is a high-performance, miniature ball bearing designed for applications requiring compact size, smooth operation, and high-speed capabilities. This bearing features a single row deep groove design, enabling it to handle both radial and axial loads efficiently. The 2RS suffix indicates that the bearing is equipped with double rubber seals on both sides, providing excellent protection against dust, dirt, and moisture while retaining lubrication. With a 5mm width, this bearing is ideal for applications where space is limited but high precision and durability are essential.

Key Features:

Compact Size: Miniature design with a 5mm width, perfect for small-scale applications.
Double Rubber Seals (2RS): Protects against contamination and retains lubricant for extended performance.
High-Speed Capability: Engineered for smooth and efficient operation at high rotational speeds.
Durable Construction: Made from high-quality materials, ensuring long-lasting performance.
Low Maintenance: Sealed design reduces the need for frequent relubrication and maintenance.
Versatility: Suitable for a wide range of applications requiring precision and reliability.

Dimensions:

Parameter	Measurement (mm)
Inner Diameter (ID)	5 mm
Outer Diameter (OD)	16 mm
Width (W)	5 mm

Advantages of 625 2RS Ball Bearing:

High-Speed Performance: Designed to operate smoothly at high speeds, making it ideal for precision applications.
Contamination Protection: The double rubber seals (2RS) ensure reliable performance in harsh environments.
Compact and Lightweight: Its small size and lightweight design make it suitable for applications with space constraints.
Low Noise and Vibration: Ensures quiet operation, which is critical for sensitive applications.
Durability: High-quality materials and construction provide excellent resistance to wear and tear.

Applications:

Small Electric Motors: Used in miniature motors for appliances, toys, and precision instruments.
Medical Equipment: Ideal for devices like dental tools, pumps, and diagnostic machines requiring high precision.
Robotics: Suitable for robotic arms and small mechanical joints.
Consumer Electronics: Used in devices such as drones, cameras, and small fans.
Hobby and DIY Projects: Perfect for small-scale mechanical projects and model building.
