Miniature ball bearings


We have huge inventory of KZ ANGULAR CONTACT BALL BEARING. KZ Bearings designed to accommodate combined loads. These bearings are available in a shield and seals.

  • Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
  • Angular contact bearings are ideal for use in gearboxes, pumps, electric motors, and clutches or other high-speed applications. ACBB are commonly used in the Materials Handling, Steel Mill, Machine Tool and Wind Energy industries.

The difference between Deep groove ball bearing and Angular contact ball bearing :

Deep groove ball bearing and angular contact ball bearing are representative rolling bearings with capability of carrying radial load and bidirectional axial load, they are widely used to many applications. They are suitable for high speed rotation and low noise and vibration conditions.

Deep groove ball bearings are the most common type of bearings. It mainly tolerates radial load, and can also bear radial load and axial load at the same time. When it bears only radial loads, the contact angle is zero. When deep groove ball bearings have large radial clearance, it exhibits angular contact bearing and can tolerate large axial loads. The friction coefficient of deep groove ball bearings is very small and the limit speed is very high.

Single row angular contact ball bearings

These bearings can accommodate axial loads in only one direction, usually adjusted against each other bearing and have non-separable rings, to give it a relatively high load carrying capacity involving a large number of balls.

Double row angular contact ball bearings

With a design corresponding to two single row bearings arranged back-to-back, but where two single bearings take up too much axial space, they can accommodate radial and axial loads in either direction or tilting moments.

Widely used BALL BEARING

Today we'll talk about KZ DEEP GROOVE BALL BEARINGS this Ball bearing has are a rolling-element that performs three main functions while facilitating speed: it carries loads, reduces friction and positions the moving machine parts. Ball bearings use balls to separate two "races", or bearing rings, to reduce surface contact and friction in the mounting planes.

Ball bearings are a regularly used type of bearings and are found in many everyday items, such as skateboards, mixers, bicycles, DVD players, and printers. This type of bearing is commonly used in applications that have high speed and low load.

Deep groove ball bearings are among the most widely consumed type of bearings in the world.

  • They can serve at high speeds and can carry radial and (limited) axial loads.
  • They are normally used in electric motors, compressors, fans, and conveyors.
  • Most common type of ball bearing. These bearings have deep raceway grooves and their race dimensions are close to the dimensions of the balls that run in the bearing.
  • 2RS & ZZ: The 2RS are sealed for life bearings i.e. the grease within the bearing may not leach out or may get contaminated into the bearing and damage. The ZZ is just a metal shield to prevent major contamination that damages the bearing.

How the balls fixed into the bearings?

As the ball passes through the groove, it rotates and collides, the rough edges break, and the ball squeezes into a circular shape, slightly rotating the dough ball between its hands, squeezing of the balls compresses the metal, giving the balls a very hard surface.

Function of Ball Bearings: Bearings reduce friction by providing smooth metal balls or rollers and a smooth inner and outer metal surface for the balls to roll. These balls or rollers "bear" the load, allowing the device to spin easily.

How to check: In the case of small non-separable ball bearings, hold the Bearing horizontally in one hand, and then rotate the outer ring to confirm that it turns smoothly. Individual bearings such as tapered roller bearings can be seen by individually examining their rolling elements and outer ring raceways.

KZ WATCH bearings are designed for precision instrumentation with low friction, low noise and low vibration.

Our KZ brand bearings are designed to provide long life and dimensional accuracy. The advantages of KZ WATCH BEARINGS include accuracy, weight, small size and long life durability.

Today we are seeing technology growth, It's growing at a fantastic speed, and introduced us with new products in many fields including , office automotive, audio visual equipment, medical equipments and many others. The bizarre innovations put a challenge to bearing producers, The bizarre innovations put a challenge to bearing producers, there is skyrocketing demand to offer good bearings with higher performance, accuracy and reliability.

KZ Miniature ball bearings are sometimes referred to as instrument bearings or micro bearings that are very small mechanized components that include the outer ring, inner ring, balls, retainer, shield, small bearings with balls as their rolling elements. These small bearings have an outside diameter of less than (<9.525 mm) or are small bearings with an outside diameter less than or equal to ½” (≤ 12.7 mm) having a ration of outside diameter to inside diameter equal to or less than two.

These are available in inch and metric sizes, open or shielded and flanged or without flange. Miniature ball bearings are useful in a wide diversity of applications.
