Misalignments are compensated by the matched design of the housing and the radial insert bearing and the plus tolerance of the bore. Reworking of the shaft is no longer required. In addition, two self-retaining set screws that are offset by 120° securely locate the inner ring on the shaft. A suitable Allen key is supplied with every ball bearing unit. This reduces the mounting outlay to a minimum.
The Black Series Ball Bearing Units also make a convincing case during operation due to their proven FAG quality standard. The optimized internal geometry, honed raceways and high ball quality ensure quiet running and the low frictional torque of the radial insert ball bearings. This reduces the energy requirements of applications. The energy efficiency is further improved with the extremely low-friction plastic cage.
Minimum friction also involves minimum heat generation and therefore a maximum grease operating life. The ball bearing units are supplied prelubricated and can be easily relubricated via a lubrication nipple if required. The seal that is firmly staked in the outer ring retains the grease in the bearing and thus allows easier relubrication. It has a vulcanized seal lip that effectively prevent dust and water entering the bearing. To protect the seal lip against damage an outer flinger shield is fitted on the inner ring. In addition, the radial insert ball bearings have an improved anti-corrosion protection. An antirotation pin locates the outer ring firmly in the housing. The robust Black Series Ball Bearing Units are most suitable for challenging operating conditions. The relevant application requires less maintenance. This saves the operator time and money.
The FAG Black Series Ball Bearing Units are supplied with both metric and inch bore diameters. Schaeffler Group Industrial is initially offering one pillow block housing unit as well as a two bolt and a four bolt flange unit. These will be followed by further housing types and a range of diameters that will be increased successively.

MANILA, Philippines — Leading German manufacturer of high performance transmission belts, the Arntz Optibelt group, recently opened the doors to their first Philippine office in Prestige Tower, Ortigas Center.
The ribbon-cutting ceremony, followed by a dinner, was attended by Optibelt’s international representatives, including Director for Asia Pacific of Optibelt Asia Pacific Pte Ltd., Thomas Tegethoff and Managing Director of Optibelt Asia Pacific, Torsten Seifried.
With more than 300 competitors worldwide, what differentiates Optibelt from the others? And what has led big clients like Philip Morris, Lafarge, and Holcim to work with them?
“We bring service,” Seifried noted, in his inaugural speech, “We build our own engineering team to teach distributors and users how to squeeze more life out of our products.
At Optibelt, we always go further in development. Our belts ensure superior lifetime. In this field, to save the customer's money, we're number one.”
Others who attended the intimate dinner and ribbon-cutting ceremony were on site to give their support and approval of the new office. Mark Li of Bearing Center and Machinery Inc., acknowledged: “Optibelt is one of the best quality belts out there. We are very happy to have them. With Optibelt, we can maximize everything.”
Oliver Ang, President of Riken Motor Sales, agreed: “I think it’s a good move for them. We expect that it will be able to support the Philippine market. They have been very helpful in all aspects of the business, from the training and seminars, to the activities we do together.”
Asked why Optibelt initially chose the Philippines as its newest hub, Seifried replied, “We believe that the market in the Philippines is growing and they need more support. We want to give on-site support – not only through our distribution partners, but by being present ourselves.”
The Arntz Optibelt Group currently has 29 distribution offices in Europe, North and South America, and Asia. A recent breakthrough due to advantages in the drive technology also enabled them to acquire the new models of Volkswagen and BMW.
The Manila office is headed by Romulo Danao III, Country Manager, Optibelt Asia Pacific Philippine representative office.
The innovation is based on a double-row angular contact thrust ball roller bearing in O-arrangement with novel rolling elements. All areas of the conventional rolling element “ball” that are not under load are removed, which means that 15 percent of the ball diameter is cut off on both sides of the ball. The result is the so-called ball roller, being 30 percent narrower and correspondingly lighter than a true ball. A bearing equipped with ball rollers has the same functionality and accuracy as a ball bearing. Various applications, e.g. in automotive and precision engineering, already benefit from the advantages offered by ball rollers, which include less space requirement, less weight, larger grease reservoir and higher load ratings.
The simplified adjacent structure results in reduced manufacturing costs: Due to the axial displacement of the bearing rings relative to each other, the bearing can be simply bolted to planed surfaces. Moreover, high-precision bearing seating’s that support the bearing along the entire height are not required thanks to the rigid bearing design.
Mounting becomes simpler and faster: The single-piece bearing rings ensure improved transfer of the bearing’s running accuracy to the machine assembly. Moreover, a rolling bearing transportation safety device needed to hold split bearing rings together is not required. Mounting errors are thus avoided.
An increase in service life is achieved: The larger grease reservoir permits e.g. extended relubrication intervals and even maintenance-free operation in some applications. This is also supported by sealing gap systems on both sides that reliably retain the lubricant inside the bearing even at high speeds.
50 per cent less noise and 35 per cent less friction – with Generation C FAG is setting a new standard for deep groove ball bearings. One of the main reasons for the significant improved performance are the optimized osculation of the rolling elements on the rings, high ball quality and improved raceway surfaces. For example, the alterations include the more efficient HRS sealing as well as the riveted steel cage. In total, these design changes enable applications to operate much more quietly, increased efficiency and higher speeds. The operating life increases while at the same time the energy consumption is significantly reduced.
CANTON, Ohio: June 17, 2009 —The Timken Company (NYSE: TKR) is supplying tapered roller bearings for longwall shearer loaders used in underground coal mines in Poland. The loaders are produced by FAMUR Group of Poland, the largest mining machinery manufacturer in Eastern Europe.
Timken® tapered roller bearings installed in the cutter head transmission of the shearer demonstrated superior performance during field tests, proving their ability to withstand the high axial loads of the application, thus extending the service life of the equipment. Downtime is particularly costly for operators in the mining industry. Timken helps end users keep equipment up and running at a high level of performance by providing reliable bearings, as well as the seals, lubricants, diagnostic equipment and repair services to help keep bearings turning.

Toyota has granted its “Achievement Award” in the “Supply” category to Schaeffler. With this distinction the Japanese automobile manufacturer acknowledges the quality of the products and services supplied by the Schaeffler Group. Schaeffler is one of only four suppliers to have received the “Achievement Award” in recognition of their supply performance at Toyota’s “Annual Business Meeting 2009” in Brussels.
“It is a fantastic success indeed to win this recognition from a company that is well-known for being a particularly discerning customer,” says Dr. Peter Pleus, President Schaeffler Engine Systems Division.
A hydraulic support element, developed by Schaeffler for the engine valve train, was displayed as a technical example in the background of the award ceremony. Ensuring automatic valve lash adjustment, this component is used in Toyota’s new ZR engine. This four-cylinder gasoline engine comes with 1.6 and 1.8 liter cubic capacity and is, for instance, installed in the Auris and Avensis models.
Compared with the previous ZZ generation, ZR engines feature up to six percent reduced fuel consumption. This is achieved thanks to variable valve control as well as optimized friction within the engine.
