Bele Bearing Basic Technical Data 倍力轴承基本技术参数
Material 材料 The standard material for bearing rings and balls is vacuum de-gassed high carbon chromium steel which allows the high quality consistence and long bearing service life. When the application require for anti-corrosion or heat-resistance properties, stainless steel is required.

Internal Clearance 内部游隙 Bearing internal clearance is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance).
radial internal clearance(Gr)
axial internal clearance(Gt)
The radial internal clearance of a bearing is of considerable importance if satisfactory operation is to be obtained, as it greatly influences bearing performance including fatigue life, vibration, noise, heat generation, etc. Therefore, the selection of the proper radial internal clearance is one of the most important tasks when choosing a bearing.
