Carbon steel, The middle layer is rubber, which is good for waterproofing. Two-Sided dust cover; comparison of tolerance class. High-hardness bearings, superior load-bearing capacity, wear resistance, impact resistance, high temperature resistance, durability and no deformation, ensuring long-term use. Small friction and high-limit speed.Pre-Lubricated, Easy to maintain. Two steel dust shields to prevent ingress of dirt and foreign matter, anti-rust,high temperature resistance. This deep-groove sealed ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. It is made of steel material which makes it durable and resistant to deformity under heavy loads. This bearing is brand new and pre-lubricated/greased from the manufacturer so no additional lubrication is required.
