CNC: Reduce runout with ANCA's new complete tool runout compensation
Manufacturing high-quality, high-performance tools requires the Total Indicator Runout (TIR) to be perfect or minimal for overall tool life and surface finish. Runout can cause shortened tool life and poor surface finish, and in drills and reamers can result in oversized holes. A new option in ANCA's ToolRoom cures runout woes and helps to increase tool life and productivity. Read the full article.
Fluke 831 Laser Shaft Alignment Tool
Misalignment causes at least half of all damage to rotating machinery, but instead of fixing the problem, teams often just treat the symptoms by replacing bearings, couplings, and seals.

SKF plain bearings used in world's longest suspension bridge

Bearings from SKF are playing a key role in a record-breaking engineering project -- the world's longest suspension bridge, which recently opened in Turkey.
The 1915 Canakkale Bridge spans a distance of more than 4 km across the Dardanelles strait in the northwest of the country. It forms part of a larger road construction project worth more than $3 billion.
"We're excited to be part of this extraordinary endeavor," said Andreas Borek of SKF. "We co-operated with DLSY JV to analyze the requirements of bearings needed to overcome important obstacles in the project."
In total, SKF supplied more than 340 plain bearings for the bridge.
The plain bearings that were produced in Schweinfurt, Germany, are located at the top and bottom of the bridge's vertical suspender cables. They help to transfer extensive loads from the bridge's two main cables and its deck. At the same time, they accommodate radial, axial, and diagonal micro movements that occur between the bridge and its supporting cables.
As well as being able to carry high loads, the bearings must be corrosion resistant due to the bridge's coastal location. After carrying out salt-spray tests in its laboratory in Schweinfurt, SKF supplied bearings that were protected with a special surface-coating technology.
The 1915 Canakkale Bridge uses 226,000 m3 of concrete and 162,000 km (about 100,000 miles) of steel wires -- enough wire to circle the world four times.
