7000C系列 接觸角α=15°
7000AC系列 接觸角α=25°

結構特點: 以ISO為標準的LYNTB精密軸承基礎系列;
接觸角: 分15o和25o,成對使用可承受軸向負荷和徑向負荷或合成負荷。
保持架:外圈引導的酚醛樹脂夾布膠木保持架和滾動體引導的尼龍保持架可根據不同用途來選用。
中高速工況選用膠木保持架;500000≤DmN≤1000000時
中低速工況可選用尼龍保持架或膠木保持架。
速度因子: 以外圈引導酚醛樹脂夾布膠木保持架為標準;
油脂潤滑 DmN≤1000000 即 極限轉速N≤1000000/Dm Dm—軸承中徑 油(少量)潤滑 DmN≤1500000
適用范圍: 此類軸承適用范圍很廣;主要用于中高轉速的需要精密軸向定位和徑向定位,高精度旋轉等工況。
例如:數控車床主軸,各類磨床工件軸,磨床砂輪主軸,光伏切片機,真空泵,風機,精密傳動機械等。
