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 137601-6 thru 137601-8 for ground and polished glass rods or 137601-01 thru
