719 seriyali burchakli kontaktli rulmanlar

719 seriyali burchakli kontaktli rulman, ayniqsa, qattiqlik talablari yuqori bo'lgan ilovalar uchun javob beradi, chunki u ichki diametriga nisbatan eng ko'p sonli sharlarni o'z ichiga oladi va uning tashqi diametriga nisbatan eng katta mil diametrini sig'dira oladi. Bu ikki xususiyat tizimning qattiqligi uchun ayniqsa muhimdir. Mil diametrining oshishi bilan milning qattiqligi ortadi va sharlar sonining ko'payishi bilan podshipnikning qattiqligi ham ortadi.

719 series Angular Contact Ball Bearings

Yuqoridagi tuzilmada ko'rsatilganidek:

719 seriyali burchakli kontaktli rulmanlar orasida ultra engil seriyadir;

70 seriyali burchakli kontaktli rulmanlar orasida yorug'lik seriyasidir;

72 seriyali burchakli kontaktli rulmanlar orasida mustahkamlovchi seriyadir;

Ilova:

Turli xil ish sharoitlariga ko'ra, radial va eksenel yukning turli xil yuk ko'tarish qobiliyatini olish va yuqori tezlik, diametr va eksenel yuqori qattiqlik talablariga javob berish uchun ko'p jihatdan birlashtirilishi mumkin. Shuning uchun u nozik dastgoh asboblarining shpindelida keng qo'llaniladi.

719 yoki 70 seriyali rulmanlar aylanish tezligi yuqori yoki radial o'rnatish maydoni kichik bo'lsa tanlanishi kerak; og'ir yuk va nisbatan past tezlik uchun 72 seriyali rulmanlar ko'proq mos keladi.
