There is a good reason to select the right balls for the full ceramic bearings. The inner steel and outer rings of the bearing can be machined to be very tolerable. When these are matched with lightweight, high-grade ceramic balls and low lubricant. The result is a low rolling resistance perfect match.
Flange bearings are a more difficult machine, so the roundness is achievable with steel rings. It is also not possible, leading to a high level of vibration. However, the bearings have their benefits and their ability to a wide range of temperatures. Their non-magnetic quality and corrosion make them a top contender. For many applications worldwide that are too difficult.
1. Criteria for selecting bearings
When you choose the different types of bearings like journal bearing, that is right for your machinery. The below given two criteria are essential.
- Criterion 1- Ensure it could be appropriate for the machine usage environment. And the operating condition is being demanded of the bearing.
- Criterion 2- It should be easy to replace and maintain the bearings of the machine.
If these criteria are, damage can be reduced, and the time needed to replace the bearings. Corrosion will diminish when you replace it, and you can use the machine for a long time. In this way, selecting the appropriate bearing will lead to a machine design that is economically better.
2. Priority to selecting bearings
You will select the optimal bearing, based on as given below. When you choose the bearing to use, the most critical factors are a success.
- Bearing arrangements: Are you using two bearings on a single shaft?
- Bearing service life: Dimension and services life are satisfied as per your needs.
- Bearing speed, accuracy, and clearance: Does it have precision and internal clearance?
- Bearing rigidity: Does it have the required rigidity for the machine?
- Bearing lubrication: Can bearing rotate over a long period?
- Components around the bearing: What type of bearing structure are you looking at?
- Bearing mounting and dismounting: Will it give maintenance of the machine?
3. Types of bearings
- When you select the design, most people first decide the shaft's dimension to satisfy the strength. And then you choose the bearing based on that.
- If the load will be perpendicular from the shaft, use a radial bearing, and load the axial shaft.
- If the bearing load will be light, use bush bearing. If heavy load, then use roller bearings.
- If the axial load and radial load are on the single bearing, a light combined load calls for the deep-groove ball bearing. The ball bearing's angular contact is a heavy combined load, and it calls a roller bearing.
- If there is a heavy axial load, applying for both directions. Or combine two or more bearings to use a double-row bearing.
4. Installation space of the bearing
Use the boundary dimensions, choose the bearing type that will fit in your installation space. It is based on the size of the shaft or flange bearing housing.
- The dimensions are bearing outside diameter and width or height. And correspond to the specific bearing diameter as per the series.
- Combine the dimension series code with the width series. Diameter series stepped bearing outside diameter with the bearing bore diameter.
- Even bearing has the same diameter, check the different types of width or outside diameter. So, please select the appropriate bearing from among them.
- Also, select the bearing diameter of series 0, 2, or 3 if your installation space is limited. Because of the machine's downsize, choose the bearing of diameter series 9.
In the final output:
When you select the bearing that is right for your machine, it is essential that the bearing be appropriate. For the requirements of the usage environment and easily acquired for the replacement. In how to select the right bearing, Hi-bond will help you to choose the bearings' types.
According to us, choose the best type of bearing based on the size and load direction. Also, match the dimensions with the shaft and housing from the boundary of the bearing. In the last, check the performance of the bearing type which you have selected. And compare it with the other types of bearing and their criteria.
