The 624ZZ Deep Groove Ball Bearing is a high-carbon steel rotary ball bearing with 13mm outer diameter and 5mm thickness, fitted with double ZZ metal shields for dust protection, suited for light mechanical loads in compact robotics, drone motors, 3D printers, and RC model builds. This ball bearing is the compact counterpart to the 626ZZ variant covered separately — at 13mm outer diameter versus the 626ZZ’s 19mm, this 624zz bearing fits significantly smaller housings, printed bearing holders, and motor flanges where the larger 626ZZ body would not physically clear the surrounding structure.
The deep groove ball bearing’s smaller 13mm OD makes it the preferred choice for drone motor shaft support, RC car drivetrain bearings, small electric motor end caps, and inline skate and scooter wheel bearings — all applications where the compact form factor saves weight and fits tighter bearing pockets. This ball bearing for 3d printer use suits the smaller idler pulley positions and guide wheel shafts in compact 3D printers and laser cutters where a 19mm bearing would create clearance issues with adjacent frame members or pulleys.
5mm thickness, this bearing for cnc machine is thinner than the 626ZZ’s 6mm — in applications with significant axial thrust loading, this thinner bearing has less axial load capacity and builders requiring higher thrust resistance should use the thicker 626ZZ variant. Available from StemVolt, your trusted destination for robotics components and STEM DIY kits at competitive prices. This 624ZZ deep groove ball bearing is ideal for robotics, mechanical assemblies, and smooth rotary motion.
