Square Bearings and Linear Rails

Simplicity™ square bearings and plugs offer the same characteristics of the standard round-way Simplicity™ bearings, but in a square package. The single, square shaft allows offset loads on a single shaft. This maintains radial integrity and reduces the number of costly components by eliminating the need for parallel shafting. The square bearings are available in 2-sided and 4-sided versions for options in adjustability. The housings are anodized aluminum and the easily replaced bearing plugs are 316 stainless steel lined with Frelon™. The addition of tapped mounting holes on each face of the square bearing offers mounting flexibility.
