Timken’s Mark Ward – Meet the Engineer

Saturday, February 23rd, 2013

The Timken Company now presents a brand new line of Type E tapered roller bearing housed units that set a new performance standard when it comes industrial bearings. They come with newly improved performance bearings lip seals, corrosion-resistant housings and locking collars. These features have advanced operating levels as compared to current industry top designs utilizing standard Timken bearings, along with 55 percent longer design life, 10 times more sealing ability, as well as more advanced corrosion resistance.

Ball Bearings

Friday, February 15th, 2013

A ball bearing refers to a specific type of rolling element bearing that uses balls, which is responsible for keeping the moving parts of a bearing separated. Such tools aid in minimizing the rotational friction, as well as the radial and axial loads. It is possible for ball bearings to achieve such with the help of at least two races, which have the balls and shift the loads through the balls. In some cases, one of the races is fastened into place.

The balls rotate as one of those races rotates. Considering the balls are rolling, they have a relatively lower coefficient of friction. The thing that lets them have a lower load capacity for their size is the small surface of the balls between the races. The production costs of ball bearings are quite inexpensive, making them the most affordable type of bearing.

Various types of ball bearing mechanisms are available in the market today, and they have their own different applications. Here is some of the terminology:

  • • Aircraft bearings: These are bearings that are utilized within the aircraft industry.
  • • Airframe bearings: This type of bearing is built for use in the control systems and surfaces of aircraft.
  • • Angular contact bearing: are designed such that there is an angle between the races and the balls when the bearing is in operation.
  • • Anti-friction bearing: A term used to describe bearing that makes use of rolling motion to support a load and reduce friction.
  • • Ball bearing: A bearing using balls as the rolling element. It is a specific type of anti-friction bearing that come with metal balls, giving rolling motion and lessening friction between moving parts.
  • • Ball cage: This refers to a device that partly surrounds the balls and travels with them.
  • • Ball complement: It is the number of balls utilized in a ball bearing.
  • • Cone: Inner ring of tapered roller bearing.
  • • Double row bearing: A type of roller-element bearing consisting of a double-row of rolling elements.

There are also many different uses for ball bearings, some of the common purposes are:

  • • Automobile wheels
  • • Bicycle wheels
  • • Dental equipment
  • • Machine tools including drills, lathes, milling machines, and others
  • • Washing machine drums
