What are the types of seals and shields used in deep groove ball bearings?

Open Type: No seals or shields, suitable for general use with periodic lubrication. Shielded Type (ZZ,): Non-contact metal shields protect against debris while maintaining low friction. Contact Sealed Type (DD): Contact seals provide excellent dust and water resistance.

What are the standard dimensions and tolerances for deep groove ball bearings?

Inner Diameter (d): Ranges from 1 mm to 10 mm. Outer Diameter (D): Sizes span 3 mm to 19 mm. Width (B): Varies from 1 mm to 6 mm, depending on the series. Precision: JIS Grade 0

What types of lubrication are suitable for deep groove ball bearings?

Sealed bearings other than open type bearings are filled with an appropriate amount of grease. Li grease (Polyol ester + Diester is used for general bearings. When applying grease at maintenance, use the same type of grease. For open type bearings, be sure to use grease suitable for the operating environment. If you need further information, please refer to below link. catalog06.pdf

What is bearing number?

Bearing numbers are alphanumeric combinations that indicate the bearing type, boundary dimensions, internal clearance, dimensional and running accuracies, and other related specifications. If you need further information, please refer to below link. catalog02.pdf
