Bearing Handles for Sally's Rolling Pin

Bearing Handle for Sally's Pro Rolling Pin.

🔩 Required Components (per handle)

Metal Parts

• 1× M8x80 mm screw
• 2× 608ZZ Ball Bearings (8×22×7 mm)
  

🔧 Functional Principle

• The M8 screw forms the fixed axle.
• The 608ZZ ball bearings sit in the handle.
• The roller rotates on the screw.
• The spacers ensure a defined distance and prevent axial tension.
• The press fit of the ball bearings prevents any play in the handle.

🧰 Assembly Instructions

• Press bearing No.1 into the front of the handle.
  1. The tight fit is intentional to prevent wobbling or rattling later.
  2. I used the socket wrench with extension.
• Slide bearing No.2 onto the M8x80mm screw, followed by the long spacer.
• Now push the screw into the handle.
  1. Here I also used the socket wrench.
• When the screw protrudes from the front of the handle, the small spacer ring can be slid on.
  1. This prevents rubbing between the handle and the large screw.
• The handle and the large screw can now be connected to each other.
  1. The M8 thread is already provided there at a depth of 25mm.
  2. Do not overtighten the screw; the thread length provides the necessary clamping and prevents unscrewing.

• Finally, place the lid on the handle.
