MECHANICAL SEAL STIR BEARINGS, 10MM, 1-3/4IN THREADED CONNECTION

• Dry running mechanical seal rotates with the shaft providing for a vacuum and pressure tight seal;  maximum vacuum rating is 5 Torr, maximum pressure is 2-3 PSI

• Unlike conventional PTFE Bearings, bearing will not “flake” contaminating your reaction

• All seals are made using perfluorinated O-rings providing outstanding resistance to the most aggressive chemicals

• Bearing seals are rated at up to 2000 RPM* with the seal life being 3000 hours

Our mechanical seal bearing is the only design on the market that will permit you to use your current glass, metal or PTFE covered stir shaft. The design allows you to have the flexibility of vertical adjustment and still choose your agitator diameter and style. Bearing has a ferrule and locking nut to ensure that the seal rotates properly, and is supplied complete with a gold-plated wrench. Lower joint adapters are supplied complete with perfluorinated O-rings and a loosening nut.

PLEASE NOTE: Bearing body and lower joint adapter must be ordered separately.

(*Max RPM will depend on shaft and/or agitator type along with alignment of motor and coupling. Chemglass recommends a max of 500 rpm when used with any glass vessel, lid, or shaft. Longer length stirrer shafts are required with CG-2077-M mechanical seal stir bearings.)
