Tapered roller slewing bearing.

⌀70mm Inner

⌀150mm Outer

REQUIRED:

At least 6 x M3 screws (20mm or longer)

3 print plates in 3mf file included:

1. Top inner and outer race sections
2. Bottom inner and outer race sections - NOT IDENTICAL to (1)
3. Rollers (32), 1cm diameter
   [ALTERNATIVE]: hollow roller: https://makerworld.com/en/models/32988
   [OPTIONAL] Adjust roller scale in [98%,100%] range:
   98% for more freedom. Less accurate. Corresponds to 0.3mm gap
   99% (current) - optimal for this printing profile and gap between surfaces will be 0.2mm
   100% which will have 0.1mm gap and is too tight to rotate freely

ASSEMBLY

1. Fasten the top and bottom sections of the inner race using a minimum of three M3 screws.
2. Place the assembled inner race inside the bottom part of the outer race
3. Insert all 32 rollers.
   Sealed (smaller) sides of the rollers are oriented towards the inner circle (see schematics in image previews) upwards
