Frequently Asked Questions
What is a Deep Groove in a Radial Ball Bearing?
A deep groove in a Radial Ball Bearing refers to the design of the inner and outer raceways (also referred to as races or rings), which have a deep concave spherical profile matching the profile of the balls' surface. This design provides a larger contact area, allowing the bearing to handle higher axial and radial loads. Deep Groove Ball Bearings are versatile and commonly used in automotive and industrial machinery.
Why use a deep groove ball bearing?
Deep Groove Ball Bearings are widely used due to their versatility and ability to support both radial and axial loads. Their simple design, featuring a deep raceway, allows for smooth and quiet operation with minimal friction. Deep Grooves are suitable for high-speed applications making them ideal for use in multiple applications.
What load type is a Deep Groove Ball Bearing?
Deep Groove Ball Bearings handle both radial and axial loads. They are suitable for high-speed applications and are commonly used in industries like automotive and industrial machinery due to their ability to manage mixed load types efficiently. Radial ball bearings operate at high speeds with low friction. Known for durability, they minimise wear and reduce maintenance costs.
What is the difference between a thrust ball bearing and a radial ball bearing?
Thrust ball bearings support axial loads parallel to the shaft and are used where the primary load is along the axis of rotation. Radial ball bearings, on the other hand, handle radial loads perpendicular to the shaft and can also manage some axial loads. Radial bearings are suited for high-speed applications, while thrust ball bearings are specialised to provide axial load support.
