The temperature range of a Dodge bearing can vary depending on several factors, including the material of the rings and balls, the retainer (cage), any closures such as rubber seals, and the lubricant used. Different oils and greases have different temperature ranges, and as long as the other materials in a bearing are suitable, Dodge can offer bearings with lubricants that can cope with temperatures ranging from -80°C all the way up to 300°C.
It’s important to note that rubber seals should not be used above 110°C, and chrome steel can support the same loads up to 120°C constant and 150°C intermittent.
Additionally, a simple rule for troubleshooting bearing temperatures is to have no more than 180°F (82°C) on the housing, with the bearing outer ring potentially being up to 20°F (11°C) hotter than the housing.
Overall, the temperature range of a Dodge bearing can vary depending on the specific application and the materials used, but it can generally handle temperatures within the range mentioned above.

Understanding Bearing Temperature Conditions
There is always some fluctuation in the operating temperature of bearings within motors. Individual operating temperatures depend on elements such as the application of the motor and the ambient temperature. However, as a guide, 170°F or 80°C should be considered normal.
What is acceptable limit for bearing temperature?
A simple rule for troubleshooting bearing temperatures: No more than 180 degrees Fahrenheit (82 degrees Celsius) on the housing. The bearing outer ring can be up to 20°F (11°C) hotter than the housing.
What is the max temp a bearing should be heated?
A bearing temperature that is less than 180 degrees F is typically considered acceptable (see the chart below). Of course, there may be other consequences for operating in this “good” range. A higher operating temperature will cause the bearing lubricant to deteriorate at a faster rate.
Why is bearing temperature high?
If the bearing is installed incorrectly, the accuracy is low, and the bearing has deflection, torque will be generated during rotation, causing the bearing to heat up or wear. In addition, the bearing will generate vibration, increase the noise, and increase the temperature rise.
What is the maximum temperature you can safely heat a bearing in order to facilitate installation over a shaft?
Bearings should never be heated over 120°C. This temperature mounting method cannot be used for pre-greased and sealed bearings or shielded bearings.
What is an overheated bearing?
Overheating damage may represent itself in many ways, such as babbitt discoloration, cracking, wiping or deformation. It may result from a wide range of problems, many of which stem from the lubricant flow rate, the viscosity, an interruption in the oil films and/or boundary lubrication.
What is standard temperature bearing?
The following is the temperature standard of the motor bearing. 1. General motor operating regulations stipulate that the maximum temperature of rolling bearings shall not exceed 95 degrees Celsius , and the maximum temperature of sliding bearings shall not exceed 80 degrees Celsius .
What is the ISO standard for bearing temperature?
Reference temperature of the bearing on the stationary outer ring or housing washer: θr = 70 °C. Reference temperature of the bearing environment: θAr = 20 °C. angle 0° u α u 45° 5 % of the basic static radial load rating C0r as pure radial load.
Can heat damage bearings?
Even with the initial signs of overheating, local changes to the microstructure occur and the integrity of the material is reduced. Heat cracks form at the affected areas. If overheating damage occurs, the bearing must be replaced and the causes investigated.
Why would a bearing overheat?
The issue of overheating is related to fluid friction, which is a result of fluid churning. This is a secondary effect of overfilling the cavity at the time of relubrication. Installing a relief vent port can help in this situation, but this would be only addressing the symptom rather than the cause.
