The RC bearings are made of bearing steel for durability and resistance to rust, corrosion and deformity under heavy loads, and is Shields on both sides keeping lubricant in and contaminants out.
With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance
Pack of 10 pcs steel ball bearings, double-rubber sealed deep groove.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads.
