Frequently asked question (FAQ)

Question: What are the types of seals and shields used in deep groove ball bearings?
Answer: •Open Type: No seals or shields, suitable for general use with periodic lubrication.
•Shielded Type (ZZ, Z): Non-contact metal shields protect against debris while maintaining low friction.
•Contact Sealed Type (LLU): Contact seals provide excellent dust and water resistance.
•Non-Contact Sealed Type (LLB): Offers moderate dust protection with minimal friction.
Question: What are the standard dimensions and tolerances for deep groove ball bearings?
Answer: •Inner Diameter (d): Ranges from 10 mm to 300.
•Outer Diameter (D): Sizes span 15 mm to 420 mm.
•Width (B): Varies from 3 mm to 78 mm, depending on the series.
•Precision: JIS Grade 0, 4, 5, and 6 standards ensure precision.
Question: What types of lubrication are suitable for deep groove ball bearings?
Answer: Sealed bearings other than open type bearings are filled with an appropriate amount of grease. Li grease (Albania grease) 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.
Question: What is the maximum permissible operating temperature for deep groove ball bearings?
Answer: The standard permissible temperature range is -25°C to 120°C, depending on the material and lubrication.
