Alignment Considerations of Machines with Stiff Elastomeric Couplings

| | | |

By on December 28, 2016

These types of couplings are quite common in industry, and there are various companies producing similar types of couplings.  They are capable of transmitting large amounts of torque in a reasonably small space.  They also do not require lubrication, and are quite easy to install, in most circumstances.  These attributes make them quite desirable in […]

Low Cost Thermal Diagnoses Misalignment Machinery Health

| | | | |

By on June 29, 2016

With the availability and decreasing prices of technology to help diagnose rotating machinery health, machine failure should be a diminishing concern. Thermal imaging cameras can be expensive; however, these cameras have very detailed diagnostic abilities and high resolution. Reduced cost Thermal Imaging has recently become available through various sources. I recently purchased an infrared camera […]
