Axial load bearing capacity can be accepted as a pure axial load if the deep groove ball bearing is required; normally, the accepted pure axial load must not exceed 0. 5C0. Bearings with small dimensions (inner diameter less than 12mm) and light series bearings (diameter series) 8, 9, 0 and 1) shall not accept an axial load exceeding the equivalent of 0. 25C0. Excessive axial load can greatly reduce the life of the bearing.
When the bearing is started at a low temperature or the viscosity of the lubricant is high; a larger minimum load can be required. Normally, the bearing support itself is added to the load accepted by the bearing; the minimum load required is now exceeded. If the minimum load is not reached; the bearing is required to apply additional radial load; to meet the minimum load requirement. In the application of deep groove ball bearings; usually the axial relative orientation of the inner and outer rings can be adjusted or the spring can be applied. To apply axial preload.
Scale, public service, clearance LYC standard deep groove ball bearing shape scale fits GB/T307. 1 "Rolling bearing radial bearing shape scale master plan", public service fit GB/T307. 1 "Rolling bearing radial bearing public service", The clearance fits the rules of GB/T4604 "Rolling bearing radial clearance".
The scale of the LYC standard deep groove ball bearing is usually made according to the P0 level (general level) and the clearance according to the 0 group (the basic group); if the customer has other special measures for the scale, public service and clearance (including non-standard) ;LYC

The equivalent dynamic load of an equivalent dynamic load deep groove ball bearing is not only related to the ratio of the axial load received by the bearing to the fundamental additional static load; and the different radial clearance also affects the equivalent dynamic load; radial clearance Increase; axial load bearing ability is also added. Regarding the deep groove ball bearing subjected to dynamic load; its equivalent dynamic load can be calculated as follows:
P = Fr when Fa / Fr ≤ e
P = XFr + YFa when Fa / Fr > e
In the formula:
P equivalent dynamic load; N
Fa axial load; N
Fr radial load; N
X Radial load factor Y Axial load factor Equivalent static load For deep groove ball bearings that accept static load; their equivalent dynamic load can be calculated as follows:
Po = 0. 6Fr + 0. 5Fa
When Po < Fr; Po = Fr
