Motorcycle bearings and Electric Fan Rolamento 6221 2RS 6221 ZZ 6221 2RSN 105*190*36 mm Chrome Steel Deep Groove Ball Bearings

Motorcycle bearings and Electric Fan Rolamento 6221 2RS 6221 ZZ 6221 2RSN 105*190*36 mm Chrome Steel Deep Groove Ball Bearings

Dimensions: With an inner diameter of 105 mm, an outer diameter of 190 mm, and a width of 36 mm, these bearings are relatively large - sized deep - groove ball bearings. Their larger size enables them to bear greater loads and provides more stable support, which is suitable for the working conditions of motorcycles and electric fans that require certain load - bearing capacity.
Material: Made of chrome steel, this material has high hardness and good wear - resistance, which can ensure the bearings can maintain good performance under long - term high - speed rotation and heavy - load conditions, reducing the occurrence of wear and tear and prolonging the service life of the bearings.
