Four-point Angular Contact Steel Ball Bearings

four-point-angular-contact-steel-ball-bearing

Four-point angular contact steel ball bearings are radial single-row angular contact ball bearings with raceways designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported. The bearings are separable, i.e., the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. Both inner ring halves of four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is combined with a cylindrical roller bearing. In addition, these recesses can be used to facilitate dismounting.

Features of Four-point Angular Contact Steel Ball Bearings:

-Accommodates axial loads in both directions

-Less axial space

-These bearings take up considerably less axial space than double-row bearings.

-High load-carrying capacity

-A large number of balls are incorporated, giving the bearing its high load-carrying capacity.

Separable design

-The split inner ring leads to easier mounting and dismounting of the bearing.

Improved oil flow

-Limited inner ring deformation when subjected to high clamping forces

Steel Ball Bearing Advantages:

Angular contact ball bearings offer many advantages over other types of bearings. Here are just a few of the benefits that they offer:

-High precision: Angular contact ball bearings are designed for high-precision applications. They can achieve extremely tight tolerances, making them ideal for instruments and other sensitive equipment.

-High speed: These bearings are also designed for high-speed applications. They can rotate at high speeds without sacrificing accuracy or reliability.

-Durable: Angular contact ball bearings are very durable and can withstand a lot of wear and tear. They have a long lifespan, even in demanding applications.

-Low maintenance: These bearings require very little maintenance and are easy to keep in good condition.

Application Of Steel Ball Bearing:

Steel ball bearings are one of the most versatile bearing types available. They can be used in a wide variety of applications, from high-speed precision machinery to heavy-duty equipment. Here are just a few examples of where angular contact ball bearings can be found:

-Instrumentation: Angular contact ball bearings are often used in instruments such as flow meters and speedometers, where their high precision is essential.

-Automotive: These bearings are commonly used in automotive applications, including wheels, transmissions, and differentials.

-Aerospace: Angular contact ball bearings are used in many different aerospace applications, from aircraft engines to navigation systems.

-Heavy industry: Heavy-duty

-Medical: Many medical devices, from MRI machines to dental drills, use angular contact ball bearings.

-Machines such as excavators and cranes rely on angular contact ball bearings for smooth operation.

-Angular contact ball bearings are also used in many types of pumps, from small household pumps to large industrial pumps.

-Sports: Many types of sporting equipment, from bicycles to golf clubs, use angular contact ball bearings.
