INA bearing of sealing material is metaplasia of fluoride fluoride rubber (FKM, and FPM, such as Viton) or made of fluorinated greases, bearing grease Arcanol L79V. If high temperature is inevitable, you should consider reading the relevant safety instructions. According to the user request, bearings can provide information on the data.
High adaptability
Evaluation of adaptability of high speed standard
Usually, INA bearings the highest permissible speed is dependent on the maximum allowable working temperature OK. Operating temperature depends on the bearing the heat and friction when passing out the bearings and bearing heat. To factors affecting the temperature decides to speed around the bearing type, size, precision, and bearing parts, as well as clearance, lubrication, cage structure and the load.
Thermal reference speeds in most dimensions are listed in the table. First part of bearings according to DIN 732 (draft) pointed out that conditions in the environment and in the references when the conditions are not the same, such as load, viscosity, allowing the temperature of the oil, and so on. DIN 732 was included in part II of the draft allows the rotational speed of the actual forces. INA bearing provides a diagram of the calculation easier.
Speed limit may be the same or lower than the reference speed. It considers only through mechanical limit, and must be addressed as a maximum allowable operating speed.
In addition, care should be taken in high speed and acceleration is large, INA bearing loads cannot be very small;
The speed limit
Factors determining the speed limit is mechanical limits, namely, strength or contact INA bearing parts sealed sliding velocity. Speed limit is given in the bearing tables and standard does not qualify the reference speed on-contact seals bearing the speed limit. In these cases the speed limit for quite P/C=0. 1 load, operating temperature rainfall figure of 70 degrees, oil bath lubrication, General conditions for installation.
