       新买的上面，绝大多数都涂有油脂。这些油脂主要用于防止轴承生锈，并不起润滑作用，因此，必须经过彻底清洗才能安装使用。清洗的方法是：凡用防锈油封存的进口轴承，可用汽油或煤油清洗。凡用厚油和防锈油脂如工业用凡士林防锈的，可先用10号机油或变压器油加热溶解清洗（油温不得超过100℃），把进口轴承浸入油。人，待防锈油脂溶化取出冷却后，再用汽油或煤油清洗。凡用气相剂、防锈水和其他水溶性防锈材料防锈的轴承，可用皂类基其他清洗剂，诸如664、平平加、6503、6501等清洗剂清洗用汽油或煤油清洗时，应一手捏住轴承内圈，另一手慢慢转动外圈，直至进口轴承的滚动体、滚道、保持架上的油污xx洗掉之后，再清洗净进口轴承外圈的表面。清洗时还应注意，开始时宜缓慢转动，往复摇晃，不得过分用力旋转，否则，进口轴承的滚道和滚动体易被附着的污物损伤。进口轴承清洗数量较大时，为了节省汽油、煤油和保证清洗质量，可分粗、细清洗两步进行。
