All About Ball Bearings

What are Ball Bearings?

Ball bearings are types of rolling-elements bearings that carry loads, reduce friction, and position moving machine parts while facilitating motion.

They reduce surface contact and friction across moving planes by utilizing separate two “races,” or bearing rings. Compared to flat surfaces that rub against each other, the coefficient of friction is reduced by the rotating motion of the balls.

Ball Bearings Design

Ball bearings consist of four major parts which are: 2 rings/races, the balls (the rolling elements), and the retainer (the ball separator). Angular contact ball bearings and radial ball bearings include an interior and outer ring. Angular contact ball bearings and radial ball bearings are designed to assist loads which can be oriented in a perpendicular direction to the axis of rotation, known as radial loads.

The outer race is stationary and mounts into housing. When the radial load is transferred from the bearing to the housing, the outer race also aids in that transfer. The internal race supports and guides the shaft during rotation, and it mounts onto a rotating shaft. The perform of the rolling elements is for carrying the load and distribution of the load throughout the raceways.

The rolling elements rotate at a different speed from the speed of the internal race, however they rotate across the interior race. The separator capabilities as a barrier that stops the balls from bumping into each other. The separator is situated between the balls. Thrust bearings support loads which are parallel to the axis of rotation, which are referred to as axial loads. Thrust ball bearings consist of rings of equal size.

Supplies Utilized in Balls in Ball Bearings

The material used to make rolling bearing ball bearing balls range widely and is always mainly centered on the ring’s materials. This gives assurance of the harmonization of the interplay of cage, outer ring, and internal ring within the system. This is usually important when heating or cooling of the bearings is concerned within the application. The ball bearing running properties are of importance; they have to be good. The commonest supplies used to make ball bearings are listed beneath, with their relation to the ring material:

Roller Bearing Steel 1.3505/100Cr6

This material is used for metal ball bearings. For these types of ball bearings, balls made from hardened steel are sometimes used. The material that’s often used is stainless-steel having a composition of about 1% carbon and 1.5% chrome.

Martensitic stainless-steel balls’ properties make them suitable for the production of ball bearings since they make stable components that are resistant and durable in steady operation. Balls which might be made from roller bearing metal are durable and robust. They are not highly susceptible to corrosion, and needle rollers and cylindrical rollers are made of this material.

Stainless Steel 1.4401 and 14401

This material is used for ball bearings made of plastic. These stainless steel balls are not hardened. They exceptionally resist corrosion and in addition resist saltwater and alkalis. Hardened metal balls must not be used for plastic ball bearings. The limits of the material in the plastic ring limit the maximum permissible load for the plastic ball bearings. Stainless steel balls are cheaper than glass balls.

Soda-Lime Glass

When a metal free ball bearing is required, this is when glass balls come into play. Glass balls are additionally used when the ball bearings’ chemical resistance is high. Soda-lime glass is used to make bottles, flat glass, drinking glasses, and ball bearing material. The chemical properties of soda-lime glass are superb and suitable for ball bearings normally exposed to chemical stress for a short while, however not to great chemical stress. The name lemon glass has also been given to it because of its light green color.

Borosilicate Glass

This type of glass is much more costly compared to soda-lime glass. The chemical-resistance properties of borosilicate are even greater than these of soda-lime glass, which means that it is utilized in applications that involve robust acids. The benefits of borosilicate glass are listed under:

Excellent heat resistance and in addition resistance to temperature changes

Mechanical stability

Very low coefficient of linear expansion

Aluminum Oxide

This type of material is used for balls for ceramic ball bearings. Ceramic balls made from aluminum oxide are additionally called oxide ceramics. They have a polycrystalline structure. These balls are light weight and have the following properties: good resistance to corrosion, good abrasion resistance, and good heat resistance.

They are extremely immune to corrosion, despite other influences like water, acids, and salt solutions. It is crucial that these types of balls don’t have contact with hydrochloric acid, hydrofluoric acid, strong alkaline options, and warm sulphuric acid. These types of balls are also known to be self-lubricating and they’re electrically insulating. Balls made of aluminum oxide are colored in white to ivory and are manufactured according to ASTM F 2094 Class II/III.
