Grease consumption of RU crossed roller bearing:
Generally, the amount of grease for cross-roller bearings should not be too much or too little. Too much will cause problems such as increased energy consumption, temperature rise, and affect sealing, but too little will not achieve the purpose of lubrication, so it is reasonable The grease filling amount should refer to the following points:
1. The inner cavity of the bearing should not be full filled with grease, but only half to three-quarters of the total space of the inner cavity of the bearing;
2. For bearings that are used horizontally, the amount of grease added should account for about two-thirds to three-quarters of the inner cavity space;
3. The vertically installed cross roller bearings are filled with grease, and the filling amount should occupy one-half (upper side) and three-quarters (lower side) of the inner cavity space;
4. In the environment that is prone to pollution, the bearings running at low or medium speed should fill all the space in the bearing box;
5. Before filling the high-speed bearing with grease, the bearing should be immersed in high-quality lubricating oil to avoid bearing burns due to insufficient lubricating grease on the friction surface during startup.
