Bearings are a tiny yet fundamental part. One may choose from a variety of bearing types to meet our needs. These robust bearings control the range of motion of any machine or mechanism. It marks how a particular part or piece should go. Bearings allow for linear motion, as seen in your desk drawer. FF shaft coupling bearing (ลูกปืนจับยึดปลายเพลา FF, which is the term in Thai) controls friction of the machine by preventing the parts from touching one another directly. As a result, a mechanism needs less effort or energy to disassemble the device. Let’s talk about the types of bearings available in the market.
Most Common Types Of Bearing
· Ball Bearing
The ball bearing is one of the most well-known types of bearings. It contains a little metal ball inside. It acts as an obstacle between the metal rings or races. It has a cage-like structure to keep the ball in place. Only a tiny contact patch exists between the race and the ball while the bearing is in motion. These bearings are not ideal because of their low friction torque and bearing capacity.
· Plain Bearings
It’s the most basic bearing design out there. There are no rolling components; it is just a bearing surface. Within the bearing, the shaft is turning. Its sliding friction is higher than the rolling friction it would otherwise have. Shaft rotation inside the bearing surface is one such instance.
· Roller Bearings
The load-carrying properties between the races in roller bearings are cylindrical rolling parts rather than balls. When the length-to-diameter ratio is much larger, we call that part a roller. Their linear contact with the inner and outer races may support greater loads than ball bearings.
· Magnetic Bearings
Magnetic bearings rely on magnetic levitation to keep a moving part in midair. Active Bearing and passive bearing are two popular varieties of magnetic bearings. In the Active type, an electric magnet gets activated when the shaft moves away from its central location. The inactive form requires a more complex and challenging to create a permanent or fixed magnet.
Finale Takeaway
FF shaft coupling bearing helps reduce friction between moving parts and shield moving metals from contact with each other. It eliminates the potential for wear and tear on moving parts due to friction and heat. Since low-friction rolling is put instead of sliding, energy consumption also drops.
