Revealing the mystery: Purposes of Multiple Ball Bearings
The Numerous types of Ball bearings make them a mystery for the normal people. It is difficult to know which type is for which purpose and which type to choose when you need it. So, we have come up with an article which will reveal the “mystery” of this tiny but most useful mechanical part’s types thus clarifying all your confusions.
Before proceeding to the types, you must know about the ball bearings themselves. So, here we go!
To maintain the separation between the bearing races, balls are used in some bearings. These rolling-element bearings are referred to as ball bearings.
The purpose of ball bearings is to reduce the friction and make the rotation smooth for an axis. So, the smoother the rotation and lesser the friction, the better the bearing, as simple as that!
With infinite applications, like in automobiles, medical equipment, aircraft, and general mechanical instruments, these small and precise parts have formed a special place for themselves due to their usefulness.
The most widely used types of these elements are the deep groove ball bearings, angular contact ball bearings and thrust ball bearings. Read till the end to know about them!
Deep Groove Ball Bearings
Characterized by the deep raceway grooves which have circular arcs in the inner and outer rings with the size slightly larger than that of the balls, deep groove ball bearings are known for their versatility and excellent performance.
Single row, stainless steel made, filling slot enabled and double row deep groove ball bearings are the main subtypes of these bearings.
The least requirement of maintenance, simple & non-separable design and robustness make them the best choice for the high, super high speed and low power loss requirements.
Deep groove ball bearings have found their applications in the steel industry, mining & construction, gearboxes, electric motors, semiconductors, pumps, compressors, motorcycles, wind turbines, rails, and other machinery.
Angular Contact Ball Bearings
The axially asymmetrical races are used in angular ball bearings to support the combined axial and radial loads.
The special contact angle allows these ball bearings to bear the axial loads in one direction, along with the significant radial loads.
The high-grade balls, advanced grease technology, high-quality steel, perfect contact angle and super finished raceways are the main qualities which should be looked for, in order to choose the best angular contact ball bearings.
The injection molding machines, the headsets of bicycles are some common examples where the angular contact ball bearings are used.
The shape of housing washer (the outer ring seat) decides whether the thrust ball bearings are flat seated or aligned seated. These mechanical items are powerful for sustaining the axial loads but not the radial loads.
For the single-direction thrust bearings, pressed steel cages or brass machine cages are generally used while the cages used in Double- Direction Thrust Ball Bearings are the same as those in Single-Direction type of the same diameter series.
The paper-making industries, motorcycles, mining and construction, gearbox and steel-making machinery are the general places where you can find the vast applications of the thrust ball bearings.
Having so many awesome usage and confusing applications due to the types, mixing in the mind, these are the most efficient and thus the most common ball bearings. We hope, you will never get stuck in resolving this mystery again as you know it all now!
