How to choose suitable bearings for the TY50-20-4KW hard-tooth surface gear reducer.

Choosing bearings suitable for TY50-20-4KW hard tooth surface gear reducers requires comprehensive consideration of multiple factors. The following are specific selection methods:

Analyze the load situation: Determine the direction and magnitude of the load that the bearing should bear based on parameters such as the input power of 4KW, output torque, and operating speed of the reducer. TY50-20-4KW reducer may bear both axial and radial loads simultaneously, and angular contact ball bearings such as SRG90, SR174, etc. can be considered. These types of bearings can withstand combined axial and radial loads; If mainly bearing radial loads, cylindrical roller bearings are also a good choice, such as N1016, N214, etc.

Considering the speed factor: The speed of the reducer needs to be combined with specific operating conditions, but generally speaking, ordinary bearing models can meet their speed requirements without the need to specifically choose high-speed bearings to avoid cost waste. For example, at normal speeds, both angular contact ball bearings and cylindrical roller bearings can adapt well.

Determine accuracy level: If high transmission accuracy is required for the reducer, bearings with accuracy levels such as P5 and P4 can be selected to ensure output accuracy and transmission stability.

Consider installation space: Measure the installation space of the reducer bearing chamber and the size of the transmission shaft to ensure that the size specifications of the selected bearings are appropriate. For example, if the installation space is limited, a compact bearing type can be chosen.
