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 […]
Seamless Rotary Track Design from Bishop-Wisecarver
Supplied by The Bishop-Wisecarver Corporation The Bishop-Wisecarver Corporation (BWC), a WBENC certified woman-owned company who helps manufacturers and automation solution providers engineer linear and rotary motion solutions, announced today its latest addition to their collection of rotary motion solutions: 1-Trak, a single piece track system that is completely seamless and free running with no possibility […]
Better components help prosumer 3D printers deliver better parts
Industrial type linear components will be key in low-cost desktop model 3D printers because they can deliver the accuracy and repeatability that users of these units desire. You don’t often hear about the use of linear guides and rails and other components, but these mechanical devices enable printers to deliver ±0.02 mm/m repeatability. A number […]

Haydon Kerk Introduces BGS Linear Rails
The BGS Linear Rail combines many technologies into a single integrated linear motion platform. The system provides excellent load capability and is engineered for both normal and overhanging loads. High roll, pitch, and yaw moment loading capability allows the system to maintain tight accuracy and repeatability, even in applications requiring significant cantilevered loading. At the […]
Linear Guide Rail System from SI
A linear guide rail system from Sterling Instrument features heavy-duty, low wear, low friction, quiet, maintenance- free operation, without the need for lubrication. The sliding element is a specially formulated polymer material best suited for hard-anodized aluminum rails. The combination of the two yields low abrasion, which reduces alignment problems and assembly time. The carriage […]
