SKF 608 deep groove ball bearing

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

The SKF 608 Deep Groove Ball Bearing is a high-performance, compact bearing commonly used in a variety of applications, 

particularly in industries where space is limited, and reliable performance is critical. As part of SKF’s renowned line of deep groove ball bearings, 

the 608 series is known for its durability, low friction, and versatility. This bearing is widely used in machinery, electric motors, bicycles, and small household appliances.

Design and Specifications

The SKF 608 deep groove ball bearing features an inner diameter of 8 mm, an outer diameter of 22 mm, 

and a width of 7 mm. Its small size makes it ideal for applications where space is at a premium, while still providing a high load-carrying capacity relative to its size. 

The deep groove design allows the bearing to support both radial loads (forces perpendicular to the shaft) and axial loads (forces along the shaft) in both directions, 

offering excellent versatility.

The bearing's closed design features 2 shields made of metal, providing a high level of protection against dust and contaminants while ensuring that 

the lubricant stays inside the bearing. This sealed design helps to reduce maintenance requirements and increase the overall service life of the bearing.

Materials and Construction

SKF manufactures the 608 bearing using high-quality steel, typically chrome steel, which ensures excellent resistance to wear, fatigue, 

and corrosion under normal operating conditions. 

The precision-machined inner and outer rings provide smooth rotation with minimal friction, 

while the steel balls are uniformly spaced by a steel cage that helps reduce friction and prevent wear.

Applications

The SKF 608 bearing is used in a wide range of applications, including:

• Electric motors: Found in small motors where high-speed operation and low friction are important.

• Bicycles: Commonly used in wheel hubs, pedals, and bottom brackets due to its compact size and durability.

• Household appliances: Found in devices like vacuum cleaners, fans, and printers where low maintenance and long service life are crucial.

• Toys and small machinery: Used in various hobbyist and small-scale mechanical systems.

Advantages

1. Compact Size: The small dimensions make the 608 bearing suitable for applications where space is limited.

2. Durability: Made from high-quality materials, it offers long-lasting performance, even under moderate load and speed conditions.

3. Low Friction: The design ensures smooth and efficient operation, reducing energy loss and heat generation.

4. Protection Against Contaminants: The metal shields help protect against dust, dirt, and moisture, extending the bearing's lifespan.
