This listing includes 2 pieces of fine non standard special bearings designed for compact shaft applications. The set covers several common bearing styles and sizes to provide flexible replacement options in small machinery. Included models and sizes are 695ZZW5, 619/5ZZ, 5 x 13 x 5, MR2010ZZ (10 x 20 x 6), and SB10206. The MR2010ZZ bearings measure 10 x 20 x 6 mm and are described as MR2010ZZ 10x20x6. The 5 x 13 x 5 size refers to a bearing with a 5 mm bore, 13 mm outer diameter and 5 mm width. The ZZ shield configuration indicates double shielding on the bearing designs where applicable. Key benefits Smooth and reliable operation for small shafts, reducing vibration and wear in precision assemblies. Double shield (ZZ) style on applicable bearings helps resist dust and moisture, supporting longer service life in challenging environments. Compact, versatile size range (including MR2010ZZ 10x20x6 and 5x13x5) to fit a variety of micro mechanical projects. Key attributes Functionality: ball bearings for small shaft applications.
