Inert PTFE stirrer bearings feature a totally enclosed bearing body for non-shedding, anti-whip, chemically resistant performance

The design has a composite PTFE/PEEK main internal seal and a specially fabricated glass ball-bearing for rigidity and smoothness during lengthy operation. The maximum recommended speed is 500 rpm in continuous operation. Ideal for glass, metal, or PTFE stir shafts. The bottom is a molded, inner standard taper joint. Average length is 96 mm, with a 45 mm O.D. at bearing center.

The bearings can also be used in slight vacuum or slight pressure applications.
