Thin Section Ball Bearings are extremely accurate, quiet and have a high loadcapacity. They are manufactured in three different versions. The diameter of a Thin Section Ball Bearing remains constant within a serie, even with an increased shaft diameter. This property differs from other standardized bearings. Depending on the shaft diameter a choice can be made from the various series with increasing cross-sectional dimensions. This way a higher loadcapacity can be obtained without changing the shaft diameter. With Thin Section Ball Bearings very light structures can be obtained which require little installation space.
