Rulman bilimlari ichki diamaterni hisoblash, rulman aniqligi va ichki bo'shliqni o'z ichiga oladi.
Rulmanning ichki diametri:

Ma'lumotni ko'tarish - aniqlik:
Rulmanning aniqligi, boshqacha qilib aytganda o'lchov aniqligi va aylanish aniqligi mos xalqaro standartlarga va milliy standartlarga ega.
Turli mamlakatlar uchun milliy standartlar xalqaro standartlarga mos keladi.

Ichki rulman oralig'i ichki halqa yoki tashqi halqa mahkamlanganda va o'rnatilmagan qo'zg'alganda radial yoki eksenel siljish miqdorini bildiradi. Harakat yo'nalishiga qarab, uni lamel bo'shliq va eksenel bo'shliqqa bo'lish mumkin.
Umuman olganda, chuqur bilyalı rulmanlar uchun radiusli masofani boshqaramiz, ikki qatorli burchakli aloqa bilyalı rulmanlar uchun eksenel masofani boshqaramiz.
Chuqur trubkali rulmanlar uchun radiusli bo'shliq quyida ko'rsatilgan,
