Solet cylindrus globosus gestus non separabiles sunt gestus radiales duplices-ordo, in aperto consilio ut vexillum producti. Postulantibus, DHK etiam designare potest et unum ordinem globosum rotundum gestus producere vel gestus rotundi globosi anuli exterioris findi.

Secundum magnitudinem et seriem DHK cylindri sphaerici gestus in pluribus variationibus designationis producuntur, diversa consilia diversa cylindro sphaerica designant et diversis caveis aptantur.

Partes consilii C symmetricas sphaericos globulos et centrum laxum in costa aptant cum duobus fragmentis caveam chalybem ut vexillum pressis.

Partes consilii MB habent centrum LABRICIUM, cum scutulis asymmetricis et duobus fragmentis anuli interioris equitandi et caveis aeneis solidis machinatis. Hoc consilium producitur ad magnas cylindrus sphaericas gestus ut vexillum. Tales gestus habent facultatem maiorem celeritatem.

Partes consili CA don t habent centrum flange. Sphaericis globulos symmetricas habent, et una machina solida cavea aenea aptantur.

Ma partus consilium habent laxam centrum rector anulum. Habent symmetricas scutellas, unam machinam et anulum exteriorem in caveam solidam aeneam emittentem aptatam. Huius consilii gestus sunt praesertim ad usum in applicationibus pulsum.

Sphaerica cylindrus gestus saepe etiam in bores acuminatis (i.e. lychni 1,12) adhibitis, nimirum suffixo K seu tortum gerens est 1:30, nimirum suffixo K30 pro serie 240 et 241 ut vexillum. Facillime modi sunt perferendis eum. Facilitas inscendendi huiusmodi genera utendi adaptor (H) et manicas recessus (AH) dat recta escendere in ducta vel subtilia subsellia hastili versa ad applicationes ubi summus cursus accurate non est necessarius.

Sulcus lubricus et perforata DHK cylindrus globosus gestus praeter seriem 213... generantur incorporationes simplices lineamenta re-lubricationis ut vexillum, e.g. circumferential sulcus et lubricating foramina

anulus exterior. Haec lineamenta cum suffixo W33 coniunguntur.

Misalignment

Partes globos globosae sunt optimae ad misalignments compensandae. Maximum licitum misalignment a centro positionis eorum dependet a consilio, serie et actu operante. Valores sequentes licitae sunt maximae.
