The suffixes of SKF single row deep groove ball bearings indicate the characteristics of bearing design and production, and are widely used in determining the types of bearings. Here are some of the commonly used suffixes:
1. W - This suffix is used on SKF sealed bearings to indicate that the bearing has a steel-reinforced contact seal.
2. TT - This suffix is used on SKF bearings made with two-lip contact seals, which also feature a low torque design and anti-corrosion protection.
3. TN9 - This suffix is used on SKF bearings with a non-contact seal on one side.
4. C3 - This suffix is used to indicate an increase in the internal clearance of the bearing.
5. C4 - This suffix is used to indicate an even greater increase in the internal clearance of the bearing.
6. RLS - This suffix is used on SKF deep groove ball bearings that have a deep raceway groove and can accommodate larger shafts due to a higher load capacity rating.
7. RS - This suffix is used on SKF deep groove ball bearings that have a shallow raceway groove and can hold slightly smaller shafts due to their lower load capacity rating.
8. MSI - This suffix is used on SKF bearings that have been manufactured in stainless steel and require maintenance-free operation due to their superior corrosion resistance.
9. U - This suffix is used on SKF bearings that have an improved service life due to an increased load capacity rating.
10. P - This suffix is used on SKF bearings that are pre-lubricated and require no additional lubrication.
