1. 無油潤滑或少油潤滑,適用于無法加油或較難加油的場合,可以在使用時不保養(yǎng)或少保養(yǎng); 2. 耐磨性能好,摩擦系數(shù)小,使用壽命長; 3. 可在-195℃~+280℃范圍內(nèi)使用; 4. 走合性能好,低噪音,無污染; 5. 薄壁結(jié)構(gòu),質(zhì)量輕,可縮小機(jī)械體積; 6. 在運(yùn)作時能形成轉(zhuǎn)移膜,起到保護(hù)對磨軸的作用,無咬軸現(xiàn)象; 7. 對磨軸的硬度要求低,未經(jīng)調(diào)質(zhì)處理的軸都可使用,從而降低了相關(guān)零件的加工難度; 8. 無吸水、吸油性,熱膨脹系數(shù)小,散熱性好,尺寸穩(wěn)定; 9. 鋼背面可電鍍多種金屬,因此可在腐蝕性介質(zhì)中使用,不會生銹; 目前已廣泛運(yùn)用于各種機(jī)械的滑動部位,如自動化機(jī)械設(shè)備(伸縮、搖擺、滑動、彎曲、回旋、回轉(zhuǎn)部位)油壓氣缸導(dǎo)套、齒輪泵浦、紡織機(jī)械、自動售貨機(jī)、塑膠成型機(jī)、壓鑄機(jī)、橡膠機(jī)械、煙草機(jī)、健身器材、辦公機(jī)械、液壓搬運(yùn)車、汽機(jī)車、摩托車、農(nóng)林機(jī)械等。 |
