vertical adjustment and still choose your agitator diameter and style.
The 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

Please Note: The CG-2077-M Mechanical Seal Stir Bearing housing
and components should not be cleaned or submersed in solvents.
Bearing should be removed during cleaning to prevent solvent
exposure.
FEATURES:
• Dry running mechanical seal rotates with the shaft, providing for a
vacuum and pressure-tight seal.
• Unlike conventional PTFE bearings, Chemglass’ mechanical seal stir
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 up to 2,000rpm* with the seal life being
3,000 hours.
*Max RPM will depend on shaft and/or agitator type, along with
alignment of motor and coupling. Chemglass recommends a max of
500rpm with used with any glass vessel, lid or shaft. Longer length
stirrer shafts are required for use with CG-2077-M mechanical seal stir
bearings.
