Frequently asked question (FAQ)

Question: What are the dimensional standards followed?
Answer: These bearings adhere to:
•ISO Standards: Ensure compatibility with metric and inch series worldwide.
•ANSI/ABMA Standards: Define tolerances and dimensions for the inch series in the American market. Now, MISUMI only handle Metric series.
The dimensions include the inner diameter d, outer diameter D, and width B, ensuring a precise fit.
Question: How do sealed and shielded bearings differ?
Answer: Sealed bearings (LLU, LLB) provide superior protection against contaminants like dust and moisture. Shielded bearings (ZZ, ZZA), on the other hand, block B while allowing contaminants such as dust higher rotational speeds.
Question: What are the tolerances and accuracy levels of these bearings?
Answer: These bearings meet international tolerances, offering:
•Dimensional Accuracy: For precise fits.
•Rotational Accuracy: Ensuring low vibration and noise.
Question: How do these bearings handle noise and vibration?
Answer: The low-friction design of miniature and small diameter ball bearings reduces vibration and noise, making them suitable for applications requiring high precision and quiet operation.
Question: What factors should be considered when selecting these bearings?
Answer: When choosing a miniature or small diameter ball bearing, evaluate the following:
•Load Type: Axial, radial, or combined loads.
•Operating Speed: Ensure compatibility with permissible speeds.
•Environmental Conditions: Select appropriate seals or materials for usage environment.
•Fit and Tolerances: Match dimensions and clearances to application requirements.
