特點(diǎn):軸向/徑向軸承YRT
YRT軸承由一個(gè)推力/向心座圈，一個(gè)推力/向心軸圈，一個(gè)推力墊圈，兩個(gè)滾針保持架組件和一組向心圓柱滾子組成。 座圈和軸圈有均布的安裝用螺釘孔。該型軸承具有高軸向和徑向承載能力。高傾斜剛度和極高的精度。適用于回轉(zhuǎn)工作臺，卡盤和銑刀頭以及測量和實(shí)驗(yàn)中的軸承配置。該型軸承對與之相配的設(shè)備零件的要求也較高。安裝時(shí)需控制安裝螺釘?shù)呐ぞo力矩。
軸承特點(diǎn):
1、高精度:精度可達(dá)到P4、P2級；
2、高剛性:該系列軸承均帶有預(yù)載荷；
3、高承載:可承受軸向載荷、徑向載荷、傾覆載荷。
4、高轉(zhuǎn)速:YRTS系列軸承可應(yīng)用于轉(zhuǎn)速較高的工作場合。
適用范圍:被廣泛應(yīng)用于精密回轉(zhuǎn)臺立式磨床、分度頭、滾齒機(jī)、銑齒機(jī)工件軸等精密裝置。
