Compatible with ALKO axle design without brakes, ensuring stability and reliability after installation.
The seal ring size is 25x52x7mm. The seal ring is used to ensure the sealing between the bearing and the axle, preventing dust, moisture and other impurities from entering, thereby protecting the bearing and extending its service life.
The bearing numbers are 30203 30205, which match the diameter and load requirements of the wheel to ensure the smooth operation of the wheel, and are used to carry heavier loads or adapt to larger wheel diameters.
The seal ring is made of rubber material, which is durable, wear-resistant and not easy to damage.
Contains 30203 bearings, 30205 bearings, and 2 seal rings each. Please check the wear and looseness of the wheel bearing group regularly, and replace or tighten it in time if necessary.
