Magnetic stirrer coupling (G-MRK), glass+PTFE

Magnetic stirrer coupling (G-MRK)

• Perfect combination of drive shaft with ball bearings, rotor and lower bearing made of PTFE/PEEK and a conductor made of borosilicate glass.
• Requires little space due to compact construction.
• No leakage or memory effects due to non-porous, welded rotor.
• This rotor holds the stirrer shaft by means of three stud screws which are fixed in the counterbores of the stirrer shaft.
• This provides optimum power transmission and a safe fixing.
• The 6 mm square can be fixed into the stirrer coupling or into the agitator.

Product advantages:

• Powerful transmission for ground joint size 19/26: 15 Ncm / for ground joint size 29/32 and 45/40: 50 Ncm
• No grease required
• All products which are exposed to the medium do not contain any metals
• High speed of up to max. 1.500 rpm
• High working temperatures up to +250°C are possible
• Excellent chemical resistance
• Safe to run dry
• Long durability
• Space-saving drive shaft O.D.'s for ground joint size 19/26: 28 mm / for ground joint size 29/32 and 45/40: 38 mm
