NTN Miniature and Extra Small Ball Bearings
The dimensional range of NTN miniature and extra small ball bearings Boundary dimensions for both metric and inch systems are in accordance with the internationally specified ISO and ANSI/ABMA standards. The most widely used sealed and shielded type ball bearings have a 1–2 mm wider width dimension than open type bearings.
The main variations of these NTN bearings with snap rings, which simplify the bearing housing construction and design, have also been serialized and are listed in dimension tables. Among the most generally used sealed and shielded bearings are standard ZZ and ZZA type which incorporate non-contact steel shield plates.non-contact type rubber sealed LLB and resin sealed SSA type bearings, and the NTN contact-type rubber sealed LLU bearing.
