Dimension Table of Optional Parts Applicable to BK Type
󱛏Metal Scraper (MS)
󱛠
Use the metal scraper (MS standard) to remove welding
sputters adhered to the guide shaft, stuck grease, etc.
󱛠
The metal scraper causes no damages to the guide shaft,
since it is a coil scraper made of phosphor bronze.
󱛠
The metal scraper may also be used with the SPB
bushings.
󱛏Stopper (ST)
󱛠
The stopper (ST standard) is a part used for positioning
by butting the end of the sleeve body of the shifter. It is
quenched and its accuracy will not deteriorate.
