Smallest Ball Bearings vs Largest (Part 1)

Friday, August 28th, 2015

As part of keeping you in the know, this will be a two part post featuring the descriptions and applications of the world’s smallest ball bearings, then next time, the world’s largest. Let’s jump right in.

The world’s smallest ball bearings are given the name “miniature ball bearings”, or they’re sometimes referred to simply as “small bearings”.

This type of ball bearing is ideal for high-performance, compact designs, operating at high speeds.

What Can Miniature Bearings Do?

As technology rapidly grows, it isn’t just the devices in our hands that grow smaller, but devices in all sorts of fields of work, too. That is where the tiny ball bearings come in to steal the show and help us out.

Miniature bearings can be used for medical and dental applications, office products, watches, computers, telecommunications, home entertainment, home electronics, automotive, and industrial markets.

They are specifically designed to reduce friction between moving parts in various applications that are subject to a limited amount of space. In addition, they are ideal for their minimal service requirements.

Miniature bearings are supplied in a wide range of types and designs. They are robust, and capable of handling light to moderate radial and thrust loads. These bearings are quiet-running, and typically available in stainless steel, with seals or shields, and various lubricant options.

How Small is Small?

Typically, miniature ball bearings will be smaller than an inch or two. But, the smallest? Capable of high speed rotation of more than 5,000 rpm, this ultra-small ball bearing is teeny-tiny.

It has an outside diameter of 1.50 millimeters, inside diameter of just 0.50 millimeters, and width of 0.65 millimeters. They are manufactured in stainless steel, and contain six balls with a 0.25mm diameter.

Minebea Co., Ltd., NMB’s parent company, is the producer of this specific miniature bearing. There are other companies who are looking to maximize the miniature bearing market as well, such as NSK Micro Precision Co., Ltd.

NSK Micro Precision Co., Ltd. (ISC), have manufactured a deep groove ball bearing with an outer diameter of only 2.00 mm, and bore diameter of 0.60 mm.

Both companies seek to produce even smaller diameters and thinner widths in their miniature bearings, and maintain equivalent or even better accuracy and performance compared with their conventional bearings.

Next week, we’ll take a look at how the world’s largest ball bearings work, and what they are used for. Can you guess how many times larger they are than these mini-bearings?

NSK Ceramic-Coated Ball Bearings

Friday, August 14th, 2015

We discussed the main three different types of ball bearing materials in an earlier post.

We know that ceramic bearings are more resistant to corrosion, lighter in weight, nonconductive, and can operate in temperatures of up to 1,800 degrees Farenheit. This range of characteristics make ceramic bearings versatile and valuable.

Ceramic bearings additionally offer up less noise and vibration compared with steel ball bearings.

Today, we’re going to do an overview of a specific product, the ceramic-coated ball bearings offered by trusted bearings manufacturer, NSK.

Product Overview

NSK has a major stake in power generation from wind turbines, and the growing demand for innovative technology in that sector has to do with bearing innovation.

As a major supplier, NSK is forefront in providing bearing solutions that deliver outstanding levels of reliability, heat resistance, and long life.

So, if the bearing application you’re working on produces a high-rate of bearing damage, and/or machine failures caused by electrical corrosion – in the generators of wind turbines, for example – NSK’s ceramic-coated ball bearings may be the solution to your problem.

These ceramic-coated ball bearings have high insulation resistance, and prevent deterioration by electrical corrosion.

What starts out as steel ball bearings are plasma sprayed, ensuring the ceramic is properly bonded to the bearing’s steel. Then, acrylic resin is used to further seal the coating.

Features and Benefits

  • Ceramic-coated steel bearing ring
  • Thickness of the ceramic coating is optimized
  • NSK’s plasma spray process ensures long-term durability
  • Insulation capability is optimized by the acrylic resin layer which seals the coating
  • Cost-efficiency is maximized due to increased bearing life
  • High insulation resistance
  • Lesser cost than hybrid bearings
    • Due to the elimination of costly manufacturing processes pure ceramic balls require.
  • No special preparation of the housing bore is needed
  • The thermal conductivity is unaffected between bearing and housing


  • Electric Motor
  • Electric Drive
  • Wind Turbine
  • Generator
  • Traction Motor

The NSK main company goal is to contribute to the well-being and safety of society, and protect the environment through widespread use of their technology. NSK seeks to continue focusing on meeting client expectations, and furthermore, providing new value to society as a whole. See our post about NSK’s Vision 2026 here.

NSK’s Vision 2026

Friday, August 7th, 2015

NSK’s high-quality products are used worldwide, and this November marks another anniversary in the company’s history – a BIG one.

NSK will celebrate its 100th anniversary on November 8, 2016, which puts us just one short year away.

This mile marker has evidently been on the company’s mind as well, as they’ve recently released Vision 2026 – their plan for growth and improvement for the coming ten years.

Vision 2026

In line with the NSK Corporate Philosophy, NSK Vision 2026 was developed by gathering thoughts and ideas from an array of sources, incorporating customer and staff opinions from around the world.

The NSK 100th Anniversary Committee, which was primarily composed of the company’s younger employees as well as management, ultimately took those ideas and created an agreed-upon vision for all.

Below is NSK’s public message regarding what the company is setting out to achieve in the ten years following their 100th anniversary. Source:

“We bring motion to life, to enrich lifestyles, and to build a brighter future. Dedicated to uncovering society’s needs, we set ideas in motion to deliver solutions beyond imagination. We’re NSK. And, we’re setting the future in motion.”

Setting the Future in Motion

The company’s goal to “set the future in motion” applies not only to their products, but to each and every one of their estimated 30,000 employees.

NSK encourages individuals within the company to set change in motion through their unique roles, resulting in a new movement for the company, its customers, and society.

By empowering their employees, NSK ensures it will continue making progress even in the middle of a quickly changing market.

A message from NSK President and CEO, Toshihiro Uchiyama:

“By repeatedly taking on challenges, no matter how small, the NSK Group’s 30,000 employees will work together as one to elicit the company’s all-round strength.”

Creating a Brighter Future

NSK clarifies that the ultimate goal of Vision 2026 is to help create a brighter future for all. NSK holds its role as an active and contributing member of society in very high regard.

“A brighter future” is one that allows people to enjoy a more secure, comfortable, convenient, and prosperous life. NSK strives to deliver exciting new products and services that will meet and exceed what society can imagine.

In order to do this, they pledge to constantly focus on imagining technologies, products, and services society will benefit from in the future, then work to achieve real results by putting those ideas into action.

Over the past 100 years, we’ve seen NSK create a reputation for superior quality. We’re excited to see what innovations they come up with in the century ahead.
