A uniquely designed lubricant free, self-aligning precision stirrer bearing. The saddle O-ring provides constant force and a positive seal on the stirring rod that allows vacuum operation to as low as 1mm. Ground finish rods from other manufacturers are not recommended for use with this bearing. Complete assembly includes PTFE stirrer bearing, PTFE bushing, saddle O-ring, threaded heavy wall glass adapter, and top cap. See LG-9501 for polished stirrer rods or LG-9502 for stainless steel rods.
