Precision 15 mm Double RCE Shaft
Part Number
AFE9MBDA
MAXIMUM ROTATION RATE: 4000 RPM — Never exceed maximum rotation rate when working with rotating electrodes.
This bearing assembly is tapered to fit into a standard 24/25 port on an electrochemical cell. The outer diameter of the upper portion of this special shaft is machined to a very high tolerance so that it will mate properly with the inner diameter of our gas-purged bearing assembly.
Each shaft is shipped with twenty (20) fluoroelastomer washers which are used to mount and seal the cylinder sample on the shaft. Additional replacement washers are available separately.
See “Description” tab below for special instructions on changing and tightening cylinders on this shaft.
[notice color="red"]MAXIMUM ROTATION RATE: 4000 RPM — Never exceed maximum rotation rate when working with rotating electrodes.[/notice]When changing 15.0 mm OD cylinders on this precision shaft, be very careful not to overtighten the PEEK nut onto the end of the shaft. It should only be finger tight when sealing the cylinder between two fluoroelastomer washers. If the nut on the end is overtightened, the washer may bulge and cause leakage of electrolyte into the stainless steel shaft. This can result in severe corrosion and irreparable damage to the shaft and may also affect electrochemical measurements.
Dummy inserts made from PTFE can also be purchased for general cleaning and storage of 15 mm OD RCE shafts.
