Rulmanlar kullan\u0131lacaklar\u0131 yerlere g\u00f6re \u00e7e\u015fitli hassasiyet gruplar\u0131nda imal edilirler. Her rulman\u0131n normal hassasiyette (\u00f6l\u00e7\u00fcsel veya \u00e7al\u0131\u015fma hassasiyeti olarak) olanlar\u0131 mevcuttur ancak \u00e7ok hassas yataklanan (tak\u0131m tezgah\u0131 milleri gibi) ve y\u00fcksek devirde \u00e7al\u0131\u015fan millerde kullan\u0131lacak rulmanlar\u0131n daha hassas boyut ve \u00e7al\u0131\u015fma toleranslar\u0131n\u0131n daralt\u0131lm\u0131\u015f olarak imal edilmesi gerekir. \u00c7ok hassas olmayan \u00e7al\u0131\u015fma ko\u015fullar\u0131 i\u00e7in (konvey\u00f6r gibi) gere\u011finden fazla hassasiyete sahip rulman se\u00e7ilmesi gereksiz maliyet art\u0131\u015f\u0131na sebep olur.

Rulman Bo\u015flu\u011fu<\/h4>\n

Bir rulman\u0131n i\u00e7 veya d\u0131\u015f bileziklerinden birisi sabit oldu\u011funda di\u011feri radyal veya eksenel y\u00f6nde hareket eder. Bu hareketin miktar\u0131na rulman bo\u015flu\u011fu denir. Rulman bo\u015fluklar\u0131 radyal ve eksenel olmak \u00fczere iki y\u00f6nde dikkate al\u0131n\u0131r. Rulmanlar millere m\u00fcmk\u00fcn oldu\u011funca hassas bir \u015fekilde yataklanmal\u0131d\u0131r. Tak\u0131lan rulman\u0131n bo\u015flu\u011funun ancak birka\u00e7 mikron olmas\u0131na izin verilir. Bu \u00e7al\u0131\u015fma \u015fartlar\u0131n\u0131 elde edebilmek i\u00e7in \u00e7e\u015fitli kriterler dikkate al\u0131nmak zorundad\u0131r. Rulman bileziklerindeki ve ba\u011fl\u0131 par\u00e7alardaki farkl\u0131 \u0131s\u0131 genle\u015fmeleri rulman\u0131n kas\u0131lmas\u0131na yol a\u00e7ar. S\u0131k\u0131 ge\u00e7meler rulman bo\u015flu\u011funu azalt\u0131r. Genelde uygulama yerine tak\u0131lm\u0131\u015f bir rulman\u0131n \u00e7al\u0131\u015fma bo\u015flu\u011fu, tak\u0131lmam\u0131\u015f rulman bo\u015flu\u011fundan daha k\u00fc\u00e7\u00fckt\u00fcr. Tak\u0131lmam\u0131\u015f rulman\u0131n bo\u015flu\u011fu de\u011fi\u015fik \u00e7al\u0131\u015fma \u015fartlar\u0131na ve uygulama toleranslar\u0131na uygun olarak se\u00e7ilmelidir. Bu nedenle normal bo\u015fluklu rulmanlar\u0131n yan\u0131 s\u0131ra daha k\u00fc\u00e7\u00fck ve daha b\u00fcy\u00fck bo\u015fluklu rulmanlar da vard\u0131r. Rulman bo\u015fluk gruplar\u0131 ISO 5753-1, ISO 5753-2 ve TS 6269 standardlar\u0131nda detayl\u0131 olarak tan\u0131mlanm\u0131\u015ft\u0131r. Buna g\u00f6re:
\nC2 bo\u015fluk grubu :<\/b>\u00a0Normal (C0) den k\u00fc\u00e7\u00fck bo\u015fluk
\nC0 (Normal) bo\u015fluk grubu :<\/b>\u00a0Normal bo\u015fluk (kodlama yaz\u0131lmaz)

Radyal bo\u015flu\u011fun se\u00e7iminde uyulmas\u0131 gereken kurallar pratik olarak \u015f\u00f6yle s\u0131ralanabilir:
\n1 – Normal \u00e7al\u0131\u015fma \u015fartlar\u0131nda rulman bileziklerinden birinin hafif pres ge\u00e7me toleranslar\u0131na sahip olmas\u0131 halinde Normal (C0) bo\u015fluk se\u00e7ilir.
\n2 – E\u011fer tatl\u0131 s\u0131k\u0131 yataklama gerekli ise, o zaman azalt\u0131lm\u0131\u015f radyal bo\u015fluk C2 se\u00e7ilir. Ge\u00e7melerin s\u0131k\u0131 olmamas\u0131na dikkat edilmelidir.
