Bearings are “parts that assist objects’ rotation”. They support the shaft that rotates inside the machinery. Bearings support the rotating shafts of the wheels, gears, turbines, rotors, etc. in those machines, allowing them to rotate more smoothly.  

In the Banka machine’s YouTube video about bearings, you’ll find some key features about the usage and importance of the bearing in the Lathe and other machines.

How many types of bearings are there? बेअरिंग कितने तरह के होते है ?

Here 11 types of bearings are mentioned —

  • Ball-bearing  
  • Thrust bearing
  • Needle roller bearing, 
  • Angular contact ball bearing 
  • Linear motion bearing
  • Magnetic bearing 
  • Radial ball bearing
  • Flexure bearing  
  • Spherical bearing 
  • Double row ball bearing
  • Taper Roller Bearing

What is the function of taper roller bearing? टेपर रोलर बेयरिंग का क्या काम होता है?

Tapered roller bearings are rolling element bearings that can support axial forces (i.e., they are good thrust bearings) as well as radial forces.

Why is accuracy good in ball bearings? बॉल बेअरिंग में क्यों एक्यूरेसी अच्छी मिलती है?

Ball bearings play a fundamental role in various mechanical devices with moving parts, which makes it possible for the components to move with each other with high efficiency and minimum friction.

You might be aware of this Ball bearing. It is used in Fans and they run at high RPM and their durability lasts for approximately 20 to 25 years.

The rubber bearing inside the bearing body holds the grease for years.

Where are thrust bearings used? थ्रस्ट बेअरिंग का कहाँ उपयोग होता है ?

Thrust bearings are used for carrying loads in the axial direction. They are also referred to as axial bearings. Like radial bearings, a thrust bearing contains two race rings, a set of rolling elements, and, frequently, a cage for retaining the rolling elements.

How are the bearings used in lathe machines? लेथ मशीन में उपयोग होने वाले बेअरिंग कैसे होते है ?

In lathe machine Bearings affect the speed, rotation, vibration, precision, and temperature of the machine tool, which in turn alters the quality of the final product.

Bearings are typically composed of a ring or series of rings with a ball or other rolling element that streamlines the motion of the spindle in the desired direction.

What is the importance of bearing in all types of machine? सभी टाइप की मशीन में बेअरिंग का क्या महत्व होता है ?

Function 1: Reduce friction and make the rotation more smooth

The bearings serve to reduce friction and allow for smoother rotation. This cuts down on the amount of energy consumption. This is the single most important function of bearings.

Function 2: Protect the part that supports the rotation, and maintain the correct position for the rotating shaft

A large amount of force is needed between the rotating shaft and the part that supports the rotation. Bearings perform the function of preventing damage from being done by this force to the part that supports the rotation, and also of maintaining the correct position of the rotating shaft.

When should taper roller bearings be used instead of ball bearings? कब बॉल बेयरिंग की जगह टेपर रोलर बेयरिंग यूज़ करना चाहिए?

The main difference between the ball bearing and taper roller bearing is that the taper roller bearing gets dispersed but in ball bearing the balls are separated through a cage and cannot be dispersed and in Taper roller bearing the rollers are also separated through the cage and get fits into the body and the spindle.

The reason why the Taper rolling bearings are used instead of ball bearings is that the Taper roller bearings have elongated rollers which have a much wider contact area.

How does a thrust bearing work? थ्रस्ट बेयरिंग कैसे काम करता है?

Thrust bearings are bearings with balls as rolling elements that are designed to absorb axial, i.e. thrust, forces. They absorb axial forces in the axial direction of the shaft.

When there is a stage where the spindle needs to move at high RPM with the constantly given thrust these kinds of rollers are needed.

Why do thrust bearings come cheap? थ्रस्ट बेयरिंग सस्ते क्यों आते हैं?

In thrust bearing, there is less usage of holes that’s why there is a lack of accuracy which makes it cheaper in price.

Ball-bearing and taper roller bearing which has higher RPM? बॉल-बेयरिंग और टेपर रोलर बेयरिंग जिसमें RPM अधिक होता है?

Taper roller bearing has 5 times less RPM than ball bearing; it means that the ball bearing rotates much faster than that.
