ANNA HULTMAN AND HANS SJOSTROM fof SKF Nova AB in Gothenburg Sweden explain how diamond-like coatings combine hardness with low friction helping to eliminate wear and increase bearing service life.
Hardness combined with low friction bearing surfaces can help eliminate smearing and other wear-related problems. This contributes to a significant increase in [...]

Selecting the correct gearbox can prove crucial to the success of a servo application. JOHN DURRANT of Rockwell Automation and ALAN FEINSTEIN of Bayside Motion Group discuss the issues involved.
To get the best out of a servomotor it needs to run at a fairly high speed. Unfortunately many applications require input [...]

Material choice, sizing, pulley design and geometry should all be taken into account in selecting the right pulley design.
When designing a pulley for a metal belt application, the most fundamental consideration is establishing whether it will be used as a friction or timing pulley.
A timing pulley used with a metal must [...]

Grease is penetrating into high speed and high temperature applications where oil lubrication would once have been the only option. This from NSK-RHP
Of course, grease is less fluid than lubricating oils. This has meant that traditionally it has not been suitable for high speed operations. However, the [...]

Adhering to a few simple design considerations for locking assemblies make them so much more effective. Alan Quinn studies the design advice given by Simplatroll for the Tollok range.
Applications for locking assemblies are found everywhere from simple pulley fixing to heavy duty drums and high integrity cases such as lift pulleys. [...]

Lubrication is too important to approach simplistically and without understanding. This guidance from Kluber Lubrication covers the basic lubricant types
Lubricants are divided into the following groups: gaseous, liquid, cohesive and solid. Among these, the gaseous lubricants are insignificant because construction costs for gas or air lubrication are [...]

With machines running faster than ever, excessive heat generation in speed reducers is becoming an increasing problem. We’ve been talking to the team at BAYSIDE about their ideas on keeping gearbox components suitably cool
When running continuously at high speeds, or even intermittently in some cases, speed reducers can generate temperatures high [...]
