Biographie Carbon Steel Bearings ;

Also called ‘commercial grade’, carbon steel is not stainless steel in that it instead features a carbon element of up to 2.1% in weight. The higher the carbon content, the stronger the bearing. With this, however, it becomes less ductile, has a lower melting point, and can’t operate large loads or high speeds.

The benefits of using carbon steel bearings include being the cheapest bearing material for use as well as its hardness.

This type of bearing made with carbon is commonly seen in rolling draws, locks, bikes, roller skates, and shopping carts.

Chrome Steel Bearings ;

Another type of steel bearing is the chrome steel bearing ;and it is one of the most prominent types of bearing components and materials due to the affordable costs, high hardness level, and quieter operating volume. Despite what the name might suggest, a chrome steel bearing has a low chromium level within the steel compound.

With this, the benefits of using a chrome steel bearing end with the high hardness, high-load capacity, low decibel, affordable cost, and wide accessibility. However, it requires the maintenance of lubrication and is not resistant to corrosion or chemicals.

As one of the most commonly sourced bearings the bearing supplier in Singapore and around the world, it has a wide range of industry applications. For example, vibrating motor systems, food processing machines, and linear motion components.

Motorcycle Bearing

Large numbers of bearings are used in motorcycles. Actual numbers will vary depending on the model and other structural factors, but a single motorcycle will have between 20 and 30 bearings built in. These bearings are used in key revolving parts, supporting the vehicle's running, including in the engine, the transmission, and the wheels. They help to reduce friction and to ensure that the motive power of the engine is reliably transmitted to the wheels.

The functions demanded of motorcycle bearings ;include facilitating a smooth ride due to low friction and vibration and ensuring durability. These factors have an influence on fuel consumption and safety, things that have a close relationship to our lives. NSK keeps these points in mind in its product development and optimizes design to improve people's lives and protect the global environment.

Motorcycles have become popular all over the world as a convenient means of transportation, and wherever they are found there will always be bearings rotating. People can appreciate NSK bearings and the technologies involved; the bearings are crucial for the pleasant sound of the engine and the smooth, powerful running of the bike. NSK responds to the eternal desire of riders around the globe for an exhilarating but comfortable ride and easy handling, and the company also makes a contribution to motorcycle reliability and safety. NSK continues to pursue smoothness in bearing rotation and paves the way toward a future where everyone will be able to enjoy smoother rides with reduced power losses.

Bicycle bearings: everything you need to know

Bearings often-overlooked components that actually bring life to your bicycle. You can’t steer, roll, pedal or have a functioning drivetrain without bearings.

Bicycle bearings ;are found in your hubs, bottom bracket, headset, suspension pivots, pedals, shifters… the list goes on – basically, anything that moves on your bike will have some kind of bearing in it.

The different types of bearing used on a bike

Loose ball, caged ball, bushings, needle, and cartridge are the main styles of bearing founds in cycling frames and components. Here, we explain how each type of bearing differs from another.


A bushing (also known as a bush, or sleeve bearing) is a type of plain bearing used in shock mounts, cheaper pulley wheels, and shifters.

A bushing is the simplest type of bearing and is just a sleeve that sits between two surfaces to reduce friction.

Loose ball bearings (also known as ‘cup and cone bearings)

The tried-and-true loose-ball hub designs have lasted decades and make for easily serviceable systems. ;

Loose ball bearings are commonly used everywhere on entry-level bikes, including hubs, bottom brackets, and headsets.

Although they’re the oldest, in many ways they can be superior. They are angular contact, relatively easy to maintain, and can perform exceptionally if well-adjusted.

A ball-and-retainer system is similar to a loose-ball setup but makes for less expensive assembly, and is thus favorable on entry-level components

Cartridge bearings

This cartridge system is a radial system where the application is anticipated to be vertical, but this is rarely the case on a bicycle

Cartridge bearings are the most common type of bearing used on anything but the very cheapest bikes.

These are a one-piece unit that is, usually, pressed into a bearing bore.

Cartridge systems require precision to function well but, as manufacturing technology has moved on, they have become increasingly used as a result of ever-increasing tolerances in the hub, frame, and component bores.

Needle bearings

If you look very closely, you can see a row of needle bearings inside these Speedplay Zero pedals.

Needle bearings, which are also known as roller bearings, are relatively uncommon in the cycling world.

The exception is pedals and very occasionally in headsets, but even then they’ve lost a lot of ground to newer and cheaper tech.

In a needle bearing, instead of ball bearings, the bearings themselves are cylindrical.

Lower maintenance costs

Our bearings are developed to withstand harsh environments. They ensure greater robustness and reliability. No downtime during periods of intensive work.

Toy Bearing

Toys such as radio-controlled cars, yo-yos, skateboards, tops, scooters, roller skates, and jump ropes all rely on bearings for their overall functionality. The same types of bearings that are so important for industrial applications also play a vital role in the design and structure of toys. Whether steel, ceramic, 7mm, 8mm, or 608 bearings, many gifts would never function at all without bearings.

Applications that Keep the Fun Rolling (or Spinning)

Sealed ball bearings of all different sizes are vital for remote-controlled cars. They allow operators to steer cars freely and for engines to work at high speeds.

Another toy that utilizes bearings for high performance is the yo-yo; ball bearings reduce friction while a yo-yo spins at the end of the string. Enthusiasts have used yo-yos with steel bearings for decades, but for even better performance and corrosion prevention, some yo-yos are made with ceramic, instead of steel, bearings.

There are other toys that use toy bearings, as well; ones that you wouldn’t necessarily expect to need them. For instance, many spinning tops utilize independent ball bearings to help them spin on any surface. Even top-of-the-line jump ropes have ball bearings — they often use precision and swivel ball bearings that eliminate friction and maximize the rotation speed of the rope.

Travel in Style

Why settle for walking when you can skate? Any toy with wheels will need bearings for functional, safe, and efficient operation.

Skateboards rely on 608 standard bearings to eliminate friction between the metal in each wheel and the axle it spins around. The scooter, a popular toy, is evolving into a serious mode of transportation. Both sealed and shielded bearings are used to provide maximum protection during outdoor use. Roller skating, one of the oldest recreational pastimes, would be impossible without bearings — two bearings are used per wheel to allow it to move freely.
