W 618/2 Deep Groove Ball Bearing - High-Speed, Low-Friction Applications

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

Key Features:

1. Ultra-Slim, Compact Design: The W 618/2 bearing’s thin profile makes it ideal for applications where space is at a premium but performance must not be compromised. Its compact design enables it to fit into tight spaces without sacrificing stability or reliability, making it highly suited for use in miniature motors, electronics, and medical devices.

2. High Precision and Smooth Operation: Thanks to the deep groove design and precisely machined inner and outer rings, this bearing ensures minimal vibration and smooth, high-speed rotation. This allows for consistent and quiet performance, even in high-speed environments, providing reliability in applications requiring accuracy and minimal noise.

3. Durable and Corrosion-Resistant Material: Constructed from high-grade stainless or chrome steel, the W 618/2 is resistant to wear and corrosion, ensuring it can withstand rigorous use. Its material composition makes it suitable for applications in environments where exposure to moisture or other potential contaminants could be a concern.

4. Low-Friction, Pre-Lubricated for Efficiency: Factory pre-lubrication with high-performance grease helps reduce friction and enables smoother operation over time, reducing wear and extending the bearing’s life. The lubrication also makes this bearing easy to install and low maintenance, reducing the need for frequent servicing.

5. Versatile Application Range: This miniature bearing is widely used across industries that demand high precision in compact devices. It is perfect for applications in robotics, medical equipment, small electric motors, aerospace instruments, and consumer electronics, where consistent, low-friction rotation and durability are critical.

6. Customizable Sealing Options: Although it comes in an open design for minimal friction, optional seals can be added for extra protection in applications requiring a sealed environment to keep out contaminants, dust, or moisture.

Application Examples:

• Medical Devices: The W 618/2 bearing’s small size and low noise make it suitable for medical instruments that require smooth and quiet operation.

• Robotics and Automation: Ideal for miniature robotic components where precise, stable performance is crucial.

• Consumer Electronics: Fits well in compact electronic devices, such as miniature fans and precision instruments.

• Aerospace and Automotive Instruments: Designed for high-precision instruments in aerospace and automotive fields requiring reliable and high-performance bearings in tight spaces.

The W 618/2 Deep Groove Ball Bearing combines compact design with high performance, making it an excellent choice for industries that require precise, low-maintenance bearings for modern miniature machinery and equipment. Its robust construction and smooth operation make it a reliable solution for high-speed applications in challenging environments.
