Smooth operation is.
Smooth operation is the key. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings. Utilizing a double circuit linear motion ball bearing system, the load is supported by several lines of balls inside return circuits which infinitely circulate com one side of the retainer to the other. The Linear Bearing will handle heavy and consistent use with calm, even-handed durability. This reduces friction resistance, consumes less energy and attains a far lower starting friction level than all other conventional bearings.
