Stirrer Bearings & Couplings

SciMac makes PTFE stirrer bearings to meet the challenging conditions of the laboratory, including heavy duty solid PTFE bearings for use without a Lubricant, due to the natural Lubricating qualities of PTFE. Choose the right bearing for your needs- solid PTFE®, PTFE® with a precision threaded glass taper joint or PTFE® with our Interface Stainless Steel outer shell bearing. The inner PTFE bearing shaft guide and Rulon gasket provide a good seal against the shaft by means of the tightening nut. Replacement parts can be ordered separately for all styles, including saddle O-rings, gaskets and retainers.
