Cost Considerations of Bearings

Friday, October 25th, 2013

When you deeply investigate and look into it, among the hindrances to rapid expansion of the market of ceramic bearings was the high cost of ceramics relative to steel. Truth be told, not too long ago, the price ratio between the two was more than 1000:1.

The price of steel balls has been constant, but the cost of ceramic balls has pretty much been plummeting. The reasons include enhancements in the manufacturing process and higher volumes.

The main costs linked to hydrostatic bearings are those of the fluid supply system, the expenses that come with machining every oil supply hole, and the cost of machining long straight rails or very round bores. The main cost in the air bearings are those of machining every air supply passage and machining long straight rails or very round bores with close tolerance.

Magnetic bearings may be the most expensive type of bearing there is.  Nevertheless, considering the problem they solve, effective system costs could be low compared to design solutions that make use of other bearings.

Q&A: Using a Combination of Two Types of Oils or Greases?

Friday, October 18th, 2013

Q: Is it a problem to use a combination of two types of oils/greases in the same component where they may come in contact with each other? I want to replace the grease in an existing system with different grease. I can’t clean out all the old grease. Will there be a compatibility issue between the new and old grease?

A: Given the two lubricants you will be using contain similar thickener systems and base fluids, then there would be no problems with compatibility. If there is a difference between the base fluid viscosities of the two lubricants, combining the two will cause a base fluid viscosity somewhere between the two.

A different viscosity oil may not bring about compatibility issues, but it could stir up performance problems. Thoroughly cleaning or purging the old grease from the part is essential to guarantee that the new lubricant properties are not remarkably changed as an outcome of being mixed with the old.

You must never mix perfluoropolyethers and silicone based fluids with any other base fluids. Hydrocarbons (mineral and synthetic) and ester base fluids are in some ways compatible, while clay and conventional polyurea thickeners systems must not be combined with any other thickener types as this could cause softening or breakdown of the grease.

Why Counterfeit Bearings Are A No-No

Friday, October 4th, 2013

Fake bearings are surfacing everywhere. Buyers need to be extra cautious with the bearings they buy for their equipment. They might be getting counterfeit ones. There are myriads of crooked companies that mislabel their counterfeit products and sell them as brands from reputed bearing companies. These low-quality bearings don’t just ruin your machines; chances are, they could ruin your business, too.

With counterfeit bearings, you don’t get what you pay for. When you pay for premium and get average, or even downright faulty products, you get cheated. Always see to it that you’re getting your money’s worth. Always get your products from trusted sources.

Counterfeit bearings could pose a threat to operations, to your money, and to human lives. Faulty and worn-out bearings can get damaged and fail fairly quickly. At best, they may bring about frequent equipment downtime and repair. Fake bearings can also be the reason for shutdowns in mills and production facilities, and tragic auto accidents, just to name a few morose incidents. Faulty, counterfeit bearings, could also come with legal consequences for you as a buyer and/or distributor.

For the most part, it’s hard to tell a genuine and a counterfeit bearing apart. They won’t look scratched, rusty or dirty. They might not even come cheaper. Most of the time, they look like the real deal, and will be marketed like it, too. Even its packaging could be skillfully imitated. If you ever suspect that you bought or distributed counterfeits, touch base with the premium brand manufacturer concerned.

Counterfeiting is a crime. Thus, it’s unethical. It puts lives and property at risk, considering the dubious quality of counterfeit products. It is a form of theft of intellectual property, like patents and trademarks, and repute. These are critical concepts in the economy of this day and age, enabling economic development relying upon ideas and innovations. If you buy or sell a counterfeit product, you automatically support the counterfeiting trade.
