Installation of Press-in Front Wheel Bearing

Friday, June 17th, 2016

In this video, Keith from SKF shows how to properly remove and replace a generation 1 press-in front wheel bearing with ABS tone ring.

He shows the proper tools that you will need to do this correctly and safely.

After everything is apart, Keith walks you through an inspection of the parts, checking for wear.

Then he gives a quick trick to know which side of the bearing contains the tone ring so that it can be inserted properly into the knuckle.

Finally, he shows how to put all the pieces back together.

Counterfeit Bearings Production – Watch the Raid

Friday, December 11th, 2015

Counterfeit bearings are a problem. You rely on bearings to keep your machinery running properly. When the bearings fail, you have down time.

Here’s an interesting video showing Chinese authorities performing a raid at a counterfeit bearings workshop. Low cost bearings are being branded to look like much higher quality bearings.


SKF to Supply Bearings for UTC’s Aerospace Business

Friday, July 24th, 2015

Bearings manufacturing giant, SKF, signed an agreement in June to support United Technologies Corporation’s (UTC) aerospace business as a supplier.

SKF will supply UTC with precision roller bearings, ball bearings, main shaft bearings, as well as seals, and the precision elastomeric components to be used for helicopter applications.

As an addition to the agreement, SKF has agreed to deliver engine bearings to the company Pratt & Whitney, which is a division of UTC. Pratt & Whitney intend to use the engine bearings in their Next Generation Product Family geared turbofan engines.

Long-Term Business Partners

SKF and UTC have been doing business since the 1950’s, so this agreement comes as no surprise. UTC President, Aerospace, Rutger Barrdahl noted:

“Through this contract, we ensure that SKF’s technology and bearings continue to play a part in the development of aircraft that are more fuel efficient, with lower engine noise, and deliver improved environmental performance.” Source:

Looking at the company’s profit profile, UTC was ranked number 5 in Flight Global’s 2013 Top 100 Aerospace Companies article. That’s good evidence that UTC is big business in the aerospace industry.

SKF, excited and ready to continue fortifying their relationship with UTC, has already begun delivering to UTC’s aerospace business locations.

We look forward to watching companies like SKF grow and expand their reach in various industries, and sharing with you the details when they do. It’s certainly due to their extensive research and constant effort to improve their products to meet industry needs, that the SKF family of companies continues to grow and thrive.

Four-Point Contact Bearings

Friday, June 12th, 2015

In the bearing industry today, design engineers are being challenged with the ever-growing need to create simpler designs, get rid of excess, and thereby reduce weight and cost of machinery. There just isn’t much time anymore for machinery down time, space is tight, and production demand is high. A bearing that can take on several jobs at once can be identified as an ideal piece to the puzzle. That’s why today we will go over the applications and advantages to using four-point contact ball bearings over double row bearings.

Let’s first define what a four-point contact ball bearing is – a bearing with raceways designed to support axial loads in both directions, and a radial single row angular contact. With a split inner ring, the bearing can hold a large number of balls. This gives it a high load carrying capacity. And, the outer ring can be mounted separately from the two inner ring halves.

Typical manufacturing for four-point contact ball bearings is of traditional antifriction bearing material. Of course, the application will call for any specific material, just like any other bearing. This can mean high-carbon alloy or stainless steel are necessary choices. Depending on the manufacturer, there may be other characteristics in a four-point contact bearing. SKF, for example, employs a recessed shoulder on the inner ring halves of their four-point contact ball bearings, improving oil flow during operation, and ease of dismounting.

Four-point contact bearings are primarily utilized for slow to moderate-speed applications with mainly oscillatory movements, but application specific bearings can also be designed, if needed. A thirty-five degree contact angle off the radial center line is typical, but again, this can be varied to match the application. You’ll want to contact the manufacturer for any application specific concerns.

What makes this type of bearing special, and a tremendous help in machine simplification, is that with each axial load it supports, a radial load can also be supported, simultaneously. This idea simplifies machine designs with a combination of axial, radial, and moment loads. With the four-point contact bearing taking place of double row bearings, much less space is required in the machine. Wow – so we know the four-point contact bearing can handle all three types of load, in any order thrown at it. But, besides tossing aside the need for one bearing, what other benefits do they have?

Since a four-point contact bearing can take on multiple jobs at once, a second bearing is rendered unnecessary. Without a second bearing…

  • Accuracy increases
  • No need for runout or diameter matching
  • No chance of wobble from two bearings that develop unequal runout
  • No more maintenance necessary than any other bearing (perhaps less)

As bearing technology continues to change and grow, machines are getting smaller, more dependable, and less work to maintain. These are all good things, which is why embrace these changes. Follow along with us here, as we strive to always keep you informed.

SKF Partners with Chinese for Wind Energy Market

Friday, June 5th, 2015

A press release from March 4, 2015 states that global bearings manufacturer, SKF, has strengthened their relationship with Chinese wind power gearbox manufacturer, Chongqing Gearbox Co., Ltd. The two companies mutually hope to develop more competitive solutions for the wind energy market in the recent future.

This subsidiary of China Shipbuilding Industry Corporation specializes in manufacturing gearboxes, couplings, and dampers. Through the three-year strategic partnership agreement signed in March, SKF will become Chongqing Gearbox Co., Ltd.’s main bearing supplier. SKF will also provide the Chinese company with engineering support to enhance collaboration efforts.

“We are welcoming the strategic partnership agreement since it will invigorate our already existing cooperation further. We hope for a close collaboration where we can combine our skills with goal to develop competitive solutions for the wind energy market,” says Sunny Chan, SKF Sales Director, Energy and Drives, China.

SKF’s search for wind energy collaboration across the globe comes as no surprise. SKF is not new to the wind energy market, already supplying bearings, seals, and condition monitoring systems that enable more wind-energy generation and cost-effectiveness. SKF’s engineers work to provide solutions that will optimize the reliability and performance of wind turbines. They are able to do this most effectively by partnering with equipment manufacturers and wind farm operators, just as they sought to solidify a partnership with Chongqing Gearbox Co., Ltd.

In addition, SKF is not ignorant to growing market demand for product which provide energy conservation and environmental preservation, making them an ideal partner for Chongqing Gearbox Co., Ltd. In fact, collaboration aimed to provide better solutions on the wind energy market align well with SKF’s BeyondZero portfolio, which includes products and solutions that aim to bring significant environmental benefits to their customers.

SKF’s BeyondZero initiative was designed to help preserve the balance of the atmosphere, promote efficient and responsible use of land resources, and avoid toxic discharges into water sources. SKF also lives up to their reputation for environmental care by partnering with WWF Climate Savers.

It will be exciting to see how SKF’s growing relationship with Chongqing Gearbox Co., Ltd. further enhances wind energy design. We hope to see innovative solutions on the wind energy market with increased energy production and reliability, combined with reduced operating costs, maintenance, and environmental impact. Hopefully, we won’t have to look too far ahead. SKF is setting a prime example for bearings manufacturers and the impact they can have on the global market, and on the world today, if they take on the same responsible strategies.
