Me yasa Granite shine kawai zaɓin da ake buƙata don bearings na iska?
A ka'ida, ana iya gina bearings na iska akan kayan lebur daban-daban, amma granite ya zama zaɓi na yau da kullun don saman bearings mai tsayayye a cikin aikace-aikacen da suka dace.
Kwanciyar hankali a tsawon lokaci. Domin granite yana da ƙarancin damuwa a ciki idan aka kwatanta da ƙarfe da aka yi da injina - ƙarfe yana riƙe da ragowar damuwa daga tsarin siminti da injina, wanda zai iya haifar da sauye-sauye a hankali, ƙananan girma a cikin watanni ko shekaru - saman bearing na granite yana ɗaukar ƙayyadaddun lanƙwasarsa fiye da ƙarfe daidai gwargwado. Ga bearing na iska, inda dukkan envelope ɗin aiki ya dogara da kiyaye gibin da aka sarrafa, wannan kwanciyar hankali yana da mahimmanci.
Kwanciyar Hankali. Gibin ɗaukar iska yana da ƙaramin girma—yawanci microns 5-20. Faɗaɗar zafin layin jagora yana canza wannan gibin, yana canza aikin bearing kuma yana haifar da kurakuran matsayi.
