When replacing blower bearings
, it is essential to select the right ones. You should choose a bearing that is resistant to the forces of the blower and can withstand the high pressures encountered during operation. A dry-sump design will reduce operating temperature and protect the bearings from corrosion. Wet-sump designs will increase surface drag and reduce the efficiency of the machine.
Magnetic bearings are another alternative, although they are more expensive. This technology is able to handle the high speeds required by aeration blowers. It also has fewer failure modes.
Standard housings for blower bearings have several different designs and materials. Most are made of gray cast iron, but metals of different grades and plastics are also used. Some types are made to withstand high pressure, while others are designed for lower pressures.
Other types of housings include split Plummer block housings, which simplify installation and maintenance. These housings are available for spherical roller, ball, or CARB toroidal roller bearings. They are available in single or two-piece housing bodies and are available with shaft/coupling guards.
Proper lubrication is crucial for maintaining the performance of your blower. Oil lubrication is preferred over grease. Re-lubricate as frequently as recommended by the manufacturer. If your blower is not performing properly, it may be a sign that the ball bearings have worn out.
While replacing the bearing, you should not attempt to remove or dismantle the blower. You should carefully inspect the bearing before replacing it. It is best to do so in a clean environment at room temperature. Premature handling of the bearing can cause it to wear out sooner than expected, which can result in a costly breakdown. Furthermore, you should avoid using any bearing that has been dropped or damaged.
