Kuvavanyo lwethu lwelabhoratri, sivavanye ulungelelwaniso lwe-bearing seal ezintathu kwi--30°C: isitywino somlomo esiqhelekileyo se-nitrile rubber (NBR) esine-lithium grease, isitywino somlomo se-fluorocarbon (FKM) esine-lithium grease, kunye nesitywino somlomo se-polyurethane (PU) esine-calcium sulfonate grease yokwenziwa. Uvavanyo lulinganise ukuvuza kwesitywino emva kweeyure ezingama-500 zokusebenza kwi--30°C kwigumbi elifrijiweyo, kunye ne-roller ejikelezayo kwi-300 RPM phantsi komthwalo we-radial we-50 kN.

I-NBR seal eqhelekileyo ene-lithium grease ibonise ukuvuza okukhulu ukuqala kwiiyure ezili-120 zokusebenza, kunye nokulahleka kwegrisi okulinganiselweyo kwe-4.5 grams ngeeyure ezingama-500. Izinto ze-NBR seal ziba brittle kwi--30°C - ubushushu bayo bokutshintsha kweglasi (Tg) obumalunga ne--35°C kuthetha ukuba izinto zisebenza kufutshane kakhulu nomda wazo wokuqhekeka - kwaye ukuqhekeka kwemilebe yesitywina okubangelwayo kuvumela igrisi ukuba iphume kwaye izinto ezingcolisayo zingene kwindawo yokubeka. I-FKM seal ene-lithium grease ibonise ukuvuza okuphakathi kwe-1.8 grams kwiiyure ezingama-500, kunye nezinto ze-FKM ezigcina ukuguquguquka kwi--30°C ngenxa ye-Tg yayo ephantsi ye--45°C. I-PU seal ene-synthetic calcium sulfonate grease ibonise ukusebenza kakuhle, kunye nokuvuza kwe-0.3 grams kuphela kwiiyure ezingama-500.

Ngokusekelwe kwezi ziphumo zovavanyo, ngoku sichaza izitywini zemilebe ze-polyurethane kunye negrisi ye-calcium sulfonate yokwenziwa kuzo zonke iirola ezifakelweyo ezinikezelwa kwimisebenzi yokwemba i-Central Asia. Iindleko ezongezelelekileyo zokuphucula ukusuka kwiitywini ze-NBR eziqhelekileyo ukuya kwiitywini ze-PU zimalunga ne-USD 2.50 ngerola nganye, kwaye iindleko ezongezelelekileyo zegrisi ye-calcium sulfonate yokwenziwa ngaphezu kwegrisi ye-lithium eqhelekileyo zimalunga ne-USD 0.80 nge-roller bearing fill nganye. Ngokwamava ethu, olu hlaziyo oludibeneyo lwe-seal kunye negrisi lunciphisa izinga lokungaphumeleli kwe-field bearing kwii-conveyors ezisebenza ebusika ukusuka kwi-12-15% ngonyaka ukuya kwi-2-4% ngonyaka, kwaye siyithatha njengenkcazo ebalulekileyo kuyo nayiphi na i-forged roller efakelweyo kwiimeko zemigodi ephantsi kwe-arctic.
