[Description]
Choose the weight (by material) for the Bearing Actuator and size for Shaft.

Golden Metal Bushing made from Brass. Weight around 9 grams perfect for you who prefer heavy actuator.  Weight is heavy and helps to counterbalance the handle. Good to build repetitive movement rhythm.
Silver Metal Bushing made from Aluminum. Weight around 3 grams, it is lighter than brass and durable.
White/Black Bushing made from Plastic (POM). Weight around 1 gram, put no additional weight to the actuator and plastic is maintenance free.  Light weight, barely put additional weight, good for dynamic movement.

Standard size is 14.5mm, and using different size will gave different feels when the bushing hits the Base bottom hole.  Choose Black Bushing in different size upon need.  Using different size will gave different feels when the bushing hits the Base bottom hole (restrictor).

Recommended Size for Shaft :

13.5mm Bushing for 7mm to 8.5mm Shaft
14.5mm Bushing for 9mm to 9.5mm Shaft
15.5mm Bushing for 10mm to 10.5mm Shaft
16.5mm Bushing for 11mm to 11.5mm Shaft
17mm Bushing for 12mm Shaft

Bushing and Ring are needed to only to install bearing actuator.

[Tips]
Because it puts the point of contact lower than generic actuator, you will need to compensate using slightly bigger actuator compare to generic actuator.

Golden and Silver Bushing will make metal to metal contact to the spring, better if you put some lube on the contact area to reduce friction when the shaft spins.
