These are 10 pieces of L1490ZZ 9x14x4.5 single row deep groove ball bearings with double shielding. Designed for smooth, reliable operation in compact assemblies, these bearings handle both radial loads and limited axial loads with low friction and speed potential. The double shields help prevent dirt ingress and retain lubrication, improving durability in challenging environments. Each bearing conforms to the L1490ZZ specification and matches the 9x14x4.5 mm dimensions. Key benefits Low friction, efficiency rotation for smooth operation in small assemblies Capable of speed performance typical of deep groove ball bearings Double shielding provides protection against dust and contamination while helping retain lubrication Suitable for long service life with reduced maintenance in appropriate applications Key attributes Model: L1490ZZ Type: Single Row Deep Groove Ball Bearing Size: 9 x 14 x 4.5 mm (inner diameter 9 mm, outer diameter 14 mm, width 4.5 mm) Shielding: Double Shielded (ZZ) Configuration: Deep Groove Ball Bearing Package quantity: 10 pieces Material: Not specified in the listing; refer to datasheet for exact material Compatibility: Fits standard 9 mm bore shafts and corresponding housings; suitable for 9x14x4.5 mm bearing applications Applications and use cases Replacing worn bearings in compact DC motors or gear motors with 9 mm shafts Supporting rotating shafts in small machinery, hobby projects, or lightweight drive systems that require lowfriction, reliable bearings Use in precision instrument assemblies or small equipment where dirt protection and lubrication retention are important Notes Delivered as a 10piece pack, all bearings share the same size and specifications (9x14x4.5 mm, L1490ZZ, double shielded) For performance, ensure proper mounting tolerances and compatible housings or shafts are used This description adheres to the stated model, size, shielding, and quantity while presenting clear benefits and practical applications for the L1490ZZ 9x14x4.5 single row deep groove ball bearings with double shields.
