The double short UniBearing has an open design that enables customized layouts. It is an option that is commonly used in applications with two guiderails. The UniBearing is easy to quickly install or remove without taking it apart, allowing reduced retooling and downtime and increased productivity and flexibility. The pads are mounted using stainless steel flathead socket cap screws that secure it to the housing and eliminate the need for high-cycle pads. The bearing can move or be fixed; when fixed, it allows the guardrail and assembly to move. All UniBearings come with pre-drilled brake holes and tapped mounting holes that enable attachment of accessories to a flat surface.
