Rolling element bearings are used extensively to ensure efficient and smooth operations in a number of machines that have rotary motion, starting from engines and car wheels to even medical equipment. Ball bearings are a prominent type of rolling element bearing that tends to serve a number of important functions, including reducing friction, carrying lead and positioning moving machine parts, while simultaneously facilitating motion. High-quality SKF ball bearings can easily be purchased online.
Ball bearings basically use balls to separate two bearing rings or “races”, for the purpose of reducing friction and surface contact across moving planes. The rotation of these balls causes a reduced coefficient of friction in comparison to flat surfaces rubbing against one another. As there is extremely little surface contact between races and balls, the ball bearings generally have a lower load capacity for their size, in comparison to other rolling-element bearings.
There are a number of distinguished applications and designs available for ball bearings. Their design additionally is specific to their load type and industrial application. A few common designs of SKF ball bearing include:
Angular Contact Bearings: They are designed to work under combined radial and axial loads.
Axial Bearings: These bearings are also known as thrust ball bearings, and are able to work force applied parallel to the axis of the bearing, or thrust loads.
Deep-Groove Bearings: These bearings are meant to carry both light axial and radial loads.
Linear Bearings: Such bearings are designed to facilitate movement in a single direction along a linear axis.
Self-aligning ball bearings: Having two sets of balls that are self-aligning, these bearings can carry both radial and light axial loads.
High-speed angular contact bearings: As its name implies, such bearings can handle high RPMs with a good level of precision and accuracy.
Ball bearing sizes and width vary based on their usage. No matter whether you want automotive ball bearings or bearings for industrial use, you can explore the web to find the bearing type needed for your desired application. Purchasing bearings online is quite simple.
