There may be many causes for the rising in temp of bearings of a rotary kiln.
1. Axial force of riding wheel oversize.
2. Oil selection is improper, oil viscosity is not enough.
3. Kiln body local high temperature radiation reduce lubricating oil viscosity, oil film becomes thin.
4. Radial force of riding wheel oversize, resulting in increasing the friction between axle and bearing bush.
5. check if the roller shaft or the bearing has developed pitting marks. These can break the lubrication film and raise the temp.
6. In the bearings, cooling water interrupt for a long time, resulting in temperature increment.
7. Also check ELEVATION VIEW allignment. If kiln's centreline is down from the reference slope it will addd additional load on the bearings of that pier resulting in high temp.

Temperature control laws in a workplace?
The Food Hygiene (England) Regulations 2006, Schedule 4, sets out the ways you must control the temperature of foods that are capable of supporting the growth of harmful bacteria. For high risk foods in particular, keeping them chilled or hot is the single most important control in making sure they are safe to eat. However, for controlling the temperature of the workplace, there are no specific regulations.
What is a temperature control?
a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD as input. It compares the actual temperature to the desired control temperature, or setpoint, and provides an output to a control element. The controller is one part of the entire control system. these are found in the interior climate control system, and in engine cooling system.
