    Flange Base Locking Trunnions

    Locking Trunnions

    Jig & Fixture Bases

    Trunnions are rugged, precision bearing mounts for revolving fixtures. Ideal for assembly and welding fixtures, and any other applications where the part must be accessible from all sides. For heavy loads, use Trunnions in pairs to avoid a large bending moment. One Locking Trunnion and one Revolving Trunnion are often paired together. The locking version, shown here, has a friction-cone mechanism that stops the rotor at any angle by tightening the knob handle (loosen knob again to unlock). The revolving version has a free-rotating bearing at both ends of the rotor shaft, with no locking mechanism. Choice of two sizes. Made in the USA.
