Due to their point contact between raceway and ball, deep groove ball bearings are extremely low-friction. In addition, they are suitable for particularly high speeds and even then offer low-vibration and quiet running. This makes deep groove ball bearings ideal for all types of electrical applications. Deep groove ball bearings from CW Bearing are optimized for efficiency are already making an important contribution to reducing CO2 emissions.

We can also manufacture custom sizes for you, supply special seals, or make any kinds of adjustments to the outer rings. Upload your specifications to our website or contact us. We are happy to collaborate with you on the technical details.

• Quiet, low-vibration operation
• Maximum energy efficiency
• High speeds possible
• Reliability even under difficult operating conditions
• Long service life
• Low maintenance / greased for-life
• Minimal total cost of ownership

From a bore diameter of less than 10 mm, these are referred to as miniature deep groove ball bearings. Their design and mode of operation are similar to the larger deep groove ball bearings. Thanks to their small dimensions, they are suitable for very compact applications with extremely high speeds.

Do you need a custom radial clearance, a custom grease or a flange on the outer ring? For individual variations of your miniature bearing, the comprehensive CW configurator is at your disposal.

Series such as 68 and 69 (or 618 and 619) are significantly smaller and narrower than series 60, 62 and 63 with the same bore diameter. Thin-walled bearings are ideally suited to shafts with a relatively large diameter and little installation space.

With the design-related small and light balls, very high speeds can be achieved in vehicle transmissions, for example. For shaft drives in robotics, our application experts have designed a large number of custom bearings, each with inner and outer rings of different widths.

Forestry tools or food applications are often exposed to moisture, so our stainless steel bearings are indispensable. In the case of aggressive media, we recommend our high-performance steels. We will be happy to assist you in choosing the right grease. For food applications, greases with H1 certificate are standard. Our greases are also listeria inhibiting. For outdoor applications, use special greases with good emergency running properties.

Do you want to play it safe? Then go for solid lubricant. Friction causes the polymer matrix to release the lubricant. At the same time, it provides 100% protection against dust or splash water ingress. If desired, it can also be listeria-inhibiting. No matter what you decide. We supply you with the perfect solution.

The double row deep groove ball bearing operates similarly to that of a single row. Double row deep groove ball bearings are also suitable for radial and axial loads in both directions.

With more balls, they offer higher load carrying capacity than a comparable single row deep groove ball bearing. They can also accommodate tilting moments very well. Therefore, double row deep groove ball bearings are ideal for particularly short shafts with limited installation space.

On request, double row deep groove ball bearings are also available from CW Bearing with shields and lip seals.

• Higher load carrying capacity than a comparable single row bearing 
• Less space required than two comparable single row bearings
• Optional seals to protect against dust, splash water or grease leakage
• Quiet, low-vibration operation
• Long operating life
• Low maintenance / greased for-life
• Minimum total cost of ownership
