Bearing Balls

A ball bearing is a specific kind of rolling-element bearing that uses balls to keep the bearing races apart. A ball bearing’s main functions are to support radial and axial loads and lessen rotational friction. In order to contain the balls and transport the stresses via the balls, at least two races are used. In most applications, one race is coupled to the rotating assembly, and the other is immobile (e.g., a hub or shaft). The balls also spin as a result of the rotation of one of the bearing races. The balls’ coefficient of friction is substantially lower than it would be if two flat surfaces were moving against one another since they are rolling. Due to the smaller contact area between the balls and races compared to other types of rolling-element bearings, ball bearings typically have a lower load capability for their size. They will, however, put up with some discord between the inner and outer races.

Angular Contact Ball Bearing

Inner and outer ring raceways of angular contact ball bearings are separated from one another in the bearing axis direction. This indicates that these bearings are made to support combined loads, i.e., radial and axial loads that act simultaneously. These ball bearings can have shielding, seals, or any combination of these. These act as lubricant retainers in addition to providing contamination prevention. These bearings may be constructed of plastic, ceramic hybrid materials, stainless steel, or other materials, and they may also be chrome- or cadmium-plated. Additionally, they can have solid lubrication or be pre-lubricated, re-lubricated, or both.

Single Row Angular Contact Ball Bearing

These bearings, which often adjust against a second bearing and have non-separable rings, can support axial stresses in just one direction and incorporate a large number of balls to give it a relatively high load-carrying capacity.
Single row angular contact ball bearing advantages include:

  • High capacity to handle loads
  • Dependable operations
  • Simple bearing mounting with universal compatibility

Double Row Angular Contact Ball Bearing

They have a construction similar to two single row bearings stacked one on top of the other, but they can tolerate tilting moments in addition to radial and axial loads that are applied in either direction.

The benefits of double row angular contact ball bearing include:

  • Radial and axial loads can be accommodated with less axial space in either direction.
  • Accommodates moments of tilt
  • Rigid bearing configuration

Four Points Angular Contact Ball Bearing

These particular ball bearings can only handle a small amount of radial load for a given axial load, occupy less axial space than double row bearings, and are separable. They are made to support axial loads in both directions and have a high load carrying capability.

  • takes into account axial loads in both directions.
  • High load carrying capacity with less axial space
  • Separatable style
  • enhanced oil flow
  • little inner ring deformation when strong clamping forces are applied

Deep Groove Ball Bearing

The most often used kind of ball bearings are deep groove ball bearings, which can be bought in seal, shield, and snap-ring configurations. These kind of bearings have race dimensions that closely resemble the size of the balls they hold. They are also ideal for supporting large loads. Radial and axial support are both provided by deep groove bearings. To change the relative levels of such loads, however, the contact angle cannot be changed.

Deep groove ball bearings are further classified into the following sub-types

Single Row Deep Groove Ball Bearing

The most prevalent kind of ball bearings are single-row deep groove bearings. They are widely employed. The circular arcs of the raceway grooves on the inner and outer rings are a little bit larger than the radius of the balls. Axial loads can also be imparted in either direction in addition to radial loads. They are ideal for applications requiring high speeds and little power loss because to their low torque. These bearings frequently have steel shields or rubber seals placed on one or both sides in addition to open type bearings and are pre-lubricated with grease.

Deep groove ball bearing with two rows

Design-wise, single row deep groove ball bearings and double row deep groove ball bearings are equivalent. The bearings can support radial loads as well as axial stresses in both directions thanks to their deep, unbroken raceway grooves that closely interact with the balls. These ball bearing varieties are ideal for bearing systems where a single row bearing’s load-carrying capacity is insufficient. Double row bearings in the 62 and 63 series are marginally broader than single row bearings for the same bore and outer diameter, but have a significantly larger load-carrying capability. Only open bearings are available for double row deep groove ball bearings (without seals or shields).

Ball Thrust Bearing

A special class of ball bearings developed for axial stresses are thrust ball bearings. Radial loads cannot be supported by them at all. Ball thrust bearings operate quietly, smoothly, and can handle high-speed applications.Depending on whether the load is unidirectional or bidirectional, they are offered as single direction or double direction bearings.

Single Direction Thrust Ball Bearing

Ball bearings for single-direction thrust are made up of raceway grooved bearing rings that resemble washers. Shaft washer (or inner ring) refers to the ring that is attached to the shaft, whereas housing washer refers to the ring that is attached to the housing.

Double Direction Thrust Ball Bearing

Three rings make up double direction thrust ball bearings, with the middle (central) ring being fastened to the shaft. Additionally, there are thrust ball bearings with an adjusting seat washer under the housing washer to correct for mounting or shaft misalignment. For smaller bearings and bigger bearings, respectively, pressed steel cages and machined steel cages are typically employed.

Ball Bearing Duplex

A duplex bearing is made up of two angular contact ball bearings. Possible combinations include back-to-back (type DB), both front faces pointing in the same direction, and face-to-face, which has the outer ring faces together . Radial and axial loads can be applied in either direction to DF and DB duplex bearings. When there is a significant axial load in one direction and it is important to apply the load uniformly to each bearing, type DT is utilised.Now that you are aware with the typical ball bearing designs, let’s learn about the several ways that ball bearings are constructed.
