SN300系列滚动轴承座具有多種不同的先進設計方式和廣闊的尺寸範圍，品質優良，SN300系列滚动轴承座是SKF軸承座中   常用的一種。這種設計的軸承座具有多種功能，能滿足廣泛應用的要求。
SN300 Series Rolling Block with a wide variety of advanced design methods and a wide size range, high quality, SN300 series of rolling bearings SKF Bearing Block are the most common kind. Bearing this design has multiple functions can meet the wide range of applications.
SN300系列滚动轴承座和31系列的SNL軸承座適用於：230、231和240系列球面滾子軸承和C 30和C 31系列的CARB軸承。大型的SN300系列滚动轴承座和SNL 31系列滚动轴承座是SKF從小型SNL軸承座中積累的經驗，再將其擴展至   大軸徑的應用方式。這些滚动轴承座是在SD軸承座的基礎上開發出來的，在尺寸上彼此可以互換。  
SN300 series and 31 series Bearing Block Bearing Block for SNL: 230,231 and 240 series of spherical roller bearings, and C 30 and C 31 series of CARB bearings. SN300 series of large-scale, and SNL 31 Rolling Block, Block is a series of rolling bearings SKF bearing in from the small SNL experience, and then extend it to the way the application of a larger shaft diameter. The bearing is a bearing on the basis of SD developed, in size can be interchangeable with each other.
