NMB - DDA-2015ZZ | Deep Grove Ball Bearing Single Row | 15 × 20 × 4.50 mm

Details

NMB DDA-2015ZZ is a deep grove ball bearing single row with inner diameter 15 mm, outer diameter 20 mm and width 4.50 mm. Additional specifications include bore type CYLINDRICAL, seal YES, cage YES and lubrication STANDARD.

These bearing is an ultra-thin, precision miniature deep groove ball bearing manufactured by NMB Technologies (MinebeaMitsumi Inc.). It is constructed from premium stainless steel and features double metal shields (ZZ) to protect against dust and contaminants while retaining lubrication. Engineered primarily for radial loads, though its deep-groove architecture allows it to handle light axial (thrust) loads in both directions. The non-contact nature of the metal shields ensures minimal rotational drag, making it highly efficient for low-power or battery-operated devices. Material : Constructed entirely from premium 440C martensitic stainless steel rings and balls for superior rust and corrosion resistance, paired with a high-ductility stainless steel cage assembly. Features are : Low Friction Design, Extended Operating Life, High Rotational Speed Ceiling, Wide Operating Window, High-Density Ball Complement, Maintenance-Free Life, Low Noise Operation, and Lowered Thermal Dissipation. Applications : Robotics and Automation, Medical Equipment and Laboratory Instrumentation, Aerospace, Defense & Consumer Drones, Semi-Conductor & Cleanroom Automation, Agricultural & Gardening Equipment.
