The stock Seimitsu LS-32 joysticks come with a nylon bearing that functions as the pivot for the joystick’s shaft. Well greased it performs well but can wear over time and lead to a slight amount of slop or play in the stick. To counter this Seimitsu remade the bearing in stainless steel and it comes stock in their top end Nobi sticks. Now you can have one in your LS-32! Note that this bearing is very smooth and well made and will feel silky during play however Seimitsu recommend using Shin-Etsu grease to occasionally service the stick.
