Inspections in aerospace are a must with precise requirements to exceed, especially for rivets and fasteners which are the base of every project. Thousands of various part numbers are used by both commercial and military aircraft for outstanding and pivotal applications such as engine, brake assemblies and leading airframes.
The world’s aerospace and defense prime contractor have high standards and only a small number of companies quality to meet them. Air Industries Company got in touch with Dimac SRL to provide with state of the art testing equipment since AIC is one of the companies that meet the requirements. Mario Brumini, Dimac’s after sales technician explains that when Air Industries Company came to them, they needed to inspect every aircraft rivet for dimensional acceptances, and in the end the final inspection.
Dimac’s and Aic’s goal is to offer the highest benefits in terms of trustworthiness and accuracy. Masso,p Agrati said "It was an exciting challenge to prove the excellence of our automated machinery in the USA – for one of the strictest supply chains. One of our specialties is that we are always happy to take up the challenge.”
Dimac’s MCV1 model was the answer. It is an automatic machine for complete inspection and categorization with a special function of detecting the tiniest chock and geometry imperfections on AIC’s rivets.
Mario Brumini explained how the new software developed is able to define the segment of the thread in order to inspect it by dragging and releasing a window around it. By defying a value for +Tol and -Tol, the operator is able to change the size of the envelop tolerance band.
Today we have many new advancements in bearing parts that are helping to improve the performance and life of bearings.Sour gas compressor bearings, which use three advanced materials:Silicon nitride, which is used in rolling elements; stainless steel, for use in bearing rings; and PEEK (polyetheretherketone), a high temperature plastic that can be used to create bearing cages. The use of these three materials are prolonging the life of the bearings, lasting over 10 times longer than their predecessors.
While they are more expensive upfront, over the long term they help save money. “Everybody likes a bargain, but it is often worth paying more in the short term in order to reap long-term benefits,” Kahlman said. “How many times have we gone for a cheaper option – and bemoaned the ‘false economy’ later? Says Lars Kahlman, senior application expert at SKF.
Using the ceramic material, silicon nitride (Si3N4) and conventional metal together are allowing both higher speeds and better electrical insulation. These bearings being “greased for life”, can also be used to fix an already poorly performing bearing. Because they can run at high speeds and with electrical properties, it makes them exceptionally helpful in variable speeds.
When choosing bearing parts in the past we have struggled between corrosion resistance and fatigue performance. Now with using super-tough stainless steel in hybrid bearing rings you get the best of both worlds. A long-lasting bearing ring that fights fatigue performance and corrosion at the same time.You may think replacing metal with plastic, PEEK, may seem like a poor judgement call, but it gives many benefits and even some advantages over metal. PEEK is light weight, easily mass produced in injection molding, performs well at a high temperature and is also strong and ridged with excellent creep resistance. In addition, it resists radiation and a large range of solvents.
Without companies such as, ASAP Semiconductor, there would not be such a readily available market helping to bring these new and innovative materials around the globe. The more availability will not only bring down material fabrication costs, but also help boost the aerospace industry into the future.
In 1879, the first CVT (Continuously variable transmission) was introduced and allowed for a more flexible system than the traditional mechanical transmission. As this design began to spread, many manufacturers began to develop vehicles utilizing the CVTs. It started first in a car, then motorcycles, then tractors, and finally aircrafts. This year we are met once again with technological advances that allows us to further improve the CVT. NSK Ltd, a global manufacturer of bearings, introduced a high-reliability low-torque ball bearing in 2011 during the month of July. Six years later, they have publicized their new and improved torque ball bearings which improve fuel efficiency and overall reliability. To match this new improvement, NSK has decided to name this new bearing.
“High-Reliability Low-Torque BELTOP 8 Bearings.”
There are two new improvements made to the previous 2011 model, which are: a round and smoothed groove shoulder for enhanced efficiency and a solid lubricant film that averts housing abrasion. This upgrade is similar to the upgrade of fasteners when Bryce Fastener Inc came up with the Skyfit Fastener. This fastener upgraded the traditional fastener as well, improving its reliability and upgrading its productivity. With the new design of the Skyfit Fastener, the installation process is much easier and quicker. Many parts existing in the market were old and were not as secure because they were available to the public. As these small applications are improved, we are looking towards a much more reliable and efficient way to build and design vehicles, whether they are motorcycles, cars, or aircrafts.

Schaeffler is introducing bearing with sensors integrated into the ring-shaped housing. The sensors give operators the ability to monitor equipment in variety of ways: Temperature, speed, vibration, and displacement. While the bearings are more costly than traditional ones, they make up cost in extending machine lifetime as well as uptime. Operators can monitor machine health and trends that a unit may be failing. There are many ways these sensors can be useful in increasing productivity and safety in a manufacturing environment.
It’s not uncommon for some bearings to spin thousands of revolutions per minute, twenty hours per day. A single bearing can also be the difference in an operational production line and a COO’s worst nightmare. Every minute a production line is off during operational hours can cost companies thousands. Now imagine the same bearing that failed the production line was a sensor bearing that measured heat and vibration. A responsible operator noticed bearing 34D had been steadily increasing its vibration signal and temperature for the past week. The operator replaced this bearing during downtime and production continued as scheduled. That is the ideal situation in which a sensor bearing is made for, and the extra cost was easily recouped by eliminating down time.
VarioSense bearings come in a wide range of size and voltage. They can handle temperatures below freezing, above 100 degrees celcius, and speeds up to 17,000 RPM. Aside from passively monitoring, they can also be used as controlling drives, such as limiting the amount of torque on a driveshaft. Feedback loops are extremely valuable to operators around dangerous equipment. A turbine fan in a storm may reach it’s maximum number of RPM’s and fail. A sensor bearing would apply the emergency brakes saving the turbine from destruction and possibly the lives of operators as well.
