BB90 has a 90. 5mm shell width and 37mm inner diameter and is designed so that the bearings of external cups can hide within the frame. The CeramicSpeed kit comes as two bearings, which are then pressed into the frame. Those two bearings consist of either CeramicSpeed Standard or Coated Bearings. Both feature super smooth, super round CeramicSpeed balls rotating in hardened steel

Defective parts; impossible to assemble
Two of the metal rods were not made in the proper proportion (the metal button that pops up into a hole in another bar each connects to was off from where it is supposed to be located) and were literally impossible to connect to the other two bars that they are supposed to connect to. Hence impossible to assemble. A total waste of money. Possibly the worst quality control I have ever seen.

Bad holes
Poles 1 and 2 don't click together due to poorly drilled holes, the clicker and the predrilled holes don't line up, really should return, but it's for outside, may try to fix the holes with a drill

Quick and easy assembly
This room divider is quick and easy to assemble, and does a great job at providing coverage with its large dimensions. The construction is sturdy and the divider material provides great privacy. This divider is relatively lightweight but despite just the two legs and somewhat large size, it's quite stable.
