Četru rindu konusveida rullīšu gultņi tiek plaši izmantoti dažādām velmētavām. Tas ir tāpēc, ka tie abi var izturēt slodzi no 2 virzieniem. Tedin ir profesionālis liela izmēra konusveida rullīšu gultņu projektēšanā un ražošanā smagajai rūpniecībai.
Tedina priekšrocības:
1. Augstas tīrības pakāpes materiāls:
Caurcietināts materiāls: DAYE tērauds vai BAOSHAN tērauds GCr15SiMn, GCr18Mo, 100CrMo7-4 vai importēts OVAKO tērauds;
Korpusa rūdīts materiāls: DAYE tērauds vai BAOSHAN tērauds G20Cr2Ni4A vai importēts OVAKO tērauds un TIMKEN tērauds;
2. Augsta precizitāte:
Velmētavu velmēšanas gultņiem: ISO pakāpe P5, P4;
Rezerves rullīšu gultņiem Z veida frēzēm: ISO klase P4,
Interfeisa augstuma starpība visiem gultņiem uz vienas vārpstas Mazāka vai vienāda ar 0,005 mm.
Atšķirība starp blakus esošo gultņu sienu biezumu Mazāka vai vienāda ar 0.002mm.
3. Kronēts iekšējais gredzens, sacīkšu ceļš un rullīši:Konusveida TRB rullīši: ar logaritmisku profilu,
4. Rullīšu profilu un izmēru konsekvence
Divrindu un četrrindu konusveida rullīšu gultņu koniskie rullīši ir ražoti ar tik ciešām izmēru un ģeometriskām pielaidēm, ka tie ir praktiski identiski. Tas nodrošina optimālu slodzes sadalījumu, samazina troksni un vibrāciju, kā arī ļauj precīzāk iestatīt priekšslodzi.
5. Uzlabots noguruma mūžs
6. Samazināta trokšņa vibrācija
