Cam followers with space-saving polymer outer ring design

The new CFL Series cam follower from IKO International boasts a unique, space-saving outer ring design and polymer layer that exceeds the capabilities of conventional resin-type cam followers. Many conventional cam followers press-fit a layer of resin onto the unit's standard outer ring to maintain radial load capacity and provide quiet, clean, and durable operation. However, this thicker assembly makes it difficult to fit into constrained spaces. The CFL Series significantly improves on this design with a polymer layer that is molded directly onto the IKO exclusive thin-walled steel outer ring. This construction solves the dilemma of being able to install a cam follower with special polymers, offering self-lubricating and shock-absorbing properties into existing applications.

V-Conform O-ring Belts -- the Ultra-Drive Belts

V-Conform™ Reinforced O-ring Belts from Dura-Belt are bi-modulus (rubber reinforced with elastic stretchy nylon), so they provide greater tension than solid polyurethane belts. These belts have soft, tiny ribs that conform to standard 3/16-in. roller grooves, so they can replace round elastic belts while maintaining grip and tension. Lots of benefits, including: energy savings, motorized drive roller (MDR) protection, bearing and shaft hole wear prevention, and more.

SKF bearings will help astronomers navigate the cosmos with precision

As a new version of the Very Large Array is being developed to accomplish its key science goals, SKF's technology is playing a pivotal role in charting the stars.

Swedish bearing maker SKF is providing key components for the next-generation Very Large Array (ngVLA), a $2 billion telescope system based in the United States that aims to peer deeper into the universe than ever before.

The next-generation Very Large Array will be comprised of more than 274 antennas, with 244 units in New Mexico and another 30 dishes spread out between other areas of the Southwest. More antennas will dot the continental United States, Hawaii, and Puerto Rico in the final deployment configuration. [Credit: Photo courtesy of SKF/Photographer mtex antenna technology]

 

 

 

 

The U.S. National Radio Astronomy Observatory (NRAO) is planning the ngVLA to replace the highly successful Very Large Array, a group of 28 radio telescopes that have been operating in the New Mexico desert for more than 40 years. The new, more advanced and ambitious project will include 244 antennas arranged in a series of spiral arms on the current VLA site. Another 30 dishes will extend these arms more than 1,000 km across the Southwest, with additional dishes positioned across the continental United States, Hawaii, and Puerto Rico to create a truly continental virtual telescope.

SKF technology will be integrated into the elevation control system of the prototype ngVLA antenna currently under construction by mtex antenna technology gmbH, a specialist in advanced radio telescope projects based in Germany.

SKF and mtex have worked together for more than two years and defined a bearing solution that could meet the telescope's requirements for high load capacity, low friction, and extreme precision. In use, the system must be able to point the antenna with an accuracy of less than one-thousandth of a degree, while continuously adjusting its position to compensate for the effects of wind and the Earth's rotation.

The prototype elevation control system includes two 720-mm SKF spherical roller bearings per antenna unit manufactured to unusually high accuracy to minimize thickness variations that could cause the antenna to wobble during motion. The bearings are mounted on tapered sleeves that allow the final clearance to be precisely adjusted during assembly to further reduce radial runout during operation. Finally, an SKF automatic lubrication system will minimize stick-slip and reduce friction and wear during telescope operation.

The prototype antenna will be installed at a test site in New Mexico later this year, before undergoing extensive testing over the next 18 months. If all goes according to plan, the NRAO will begin large-scale production of antennas for the ngVLA project in 2027, supporting a construction process that is expected to take a decade.
