💡 産業機械において、深溝玉軸受はどのような用途に使われるのでしょうか？
Deep groove ball bearings are handy for radial loads in compact spaces and can handle axial loads in one or both directions, making them a common choice for motors, conveyors, and gearboxes.
- high radial load capacity for heavy machinery - ideal for motors, gearboxes, and conveyors in manufacturing settings - standard 20 mm bore fits common shafts across equipment - open design requires proper lubrication and maintenance
