Updated May 2018 || When it comes to linear guide wheels, here’s what you need to know to ensure a smooth design. Linear guide systems are chosen for an application based not only on their precision and speed characteristics, but also on a host of other operating conditions such as environment, length, speed, duty cycle, […]
What You Need to Know about the 2:1 Ratio
by Jonathan R. Schroeder, Engineer The Binding Ratio is a frequently misunderstood mechanical principle, with common misconceptions still causing stalling and application failure. A closer look at the mathematics behind the rule will give you a better comprehension of how to implement it. One of the more frequently misunderstood principles regarding the use of plane […]
New dry-tech sample box from igus
Plastics specialist igus has announced the release of its dry-tech® box, an ingenious sample kit designed to help engineers find the right material bearing for their application. The box contains a set of state-of-the-art card overlays, which filter the bearing choices by criteria – similar to the igus online configurator. The dry-tech sample box includes […]

Fresh on the Table: Polymers for Increased Food Safety
Designers and operators of food production lines must adhere to strict food hygiene regulations from the FDA to ensure consumers can buy food safely. This includes avoiding any kind of contamination such as from foreign particles or lubricants during production or transport process. The use of special materials can significantly reduce this risk. Detectable polymers, […]
Corrosion — How bearings fail Part 3 of 6
Recently we examined how surface distress contributes to bearing failure. Now we’ll examine corrosion. Corrosion occurs primarily when either lubricants fail or the seals have failed and the bearings have been exposed to water or corrosive liquids. Corrosion can lead to early fatigue failures through the rust that forms in the bearing, especially if rust occurs in […]
Smearing — How bearings fail Part 5 of 6
Recently we examined how brinelling contributes to bearing failure. Now we’ll examine bearing smearing. Just a reminder: Factors that contribute to bearing failure include material fatigue; operating with a heavier loading than specified; inadequate or unsuitable lubrication; careless handling; poor sealing; and bearing balls or rollers installed too tightly, with insufficient internal bearing clearance. Each of these contributors leaves […]
Mechanical wear — How bearings fail Part 1 of 6
Today, bearing manufacturers can reliably predict the operating life of bearings, which makes it easier to specify the right bearing for an application. Bearings do fail, if for no other reason than components do not operate forever. A number of causes contribute to failure, including material fatigue; operating with a heavier loading than specified; inadequate or […]
