Load Capacity: The bearing components are ground and polished, and the individual steel balls are deformation resistant. Deep groove ball bearings primarily support radial loads and moderate axial loads. Durable Materials: Made of high-quality steel, these bearings are durable, rust-proof, corrosion-resistant, and offer smooth, quiet operation and a long service life. Sealing: The seal provides effective protection against sand, dust, water, and other foreign substances, extending the bearing's lifespan. Double-sealed bearings require less maintenance, have shorter replacement intervals, and are more economical. Various improved designs are available: for example, deep groove ball bearings with rubber seals, deep groove ball bearings with snap ring grooves, high-capacity deep groove ball bearings with filling slots, and double-row deep groove ball bearings. Many Applications: Deep groove ball bearings are used in trolleys, gearboxes, instruments, motors, household appliances, internal combustion engines, transport vehicles, agricultural machinery, construction equipment, civil engineering machinery, roller skates, tools, and more.
