Igubal pillow block bearings on pest control drone

The FitoStinger drone was developed for pest control by the TSA Center in Spain. The drone is equipped with an extendable arm, which is used to accurately spray pesticides. To treat only affected areas accurately, the drone must be both durable and lightweight. The linear guide from igus that is used in the drone consists […]

Shaft collar evolution

The first mass-produced collars were used primarily online shafting in early manufacturing mills. These early shaft collars were solid ring types, employing square-head set screws that protruded from the collar. Protruding screws proved to be a problem because they could catch on a workmen’s clothing while rotating on a shaft, and pull them into the […]

Rotary bearings: Answers to common questions

Bearings are internal machine components that are crucial to motion applications. They reduce friction between moving parts by giving a surface something on which to roll rather than slide. Rotary bearings consist of smooth rollers or metal balls and inner and outer surfaces (races) against which the rollers or balls travel. These rollers or balls […]

Locking devices: basic designs and applications

A locking device is a mechanical component that prevents mated shafts and other machine elements from moving out of position when subjected to external forces. Operating conditions such as initial installation error, temperature variations, vibration and others can all cause issues. These are critical components. The safety of an entire system often relies on locking devices. […]

A guide to ball bearing materials

By Preston Souza Product Specialist, xiros Bearings Ball bearings can be used in a range of applications, from medical and packaging technology to electronics and office technology. Since these components are available in different types of materials, each with their own set of features and benefits, weighing the pros and cons of a specific kind […]

Thordon and IMarEST support water lubricated propulsion systems

Shipping industry leaders attending London International Shipping Week (LISW) next week will be able to hear the case for water lubricated propeller shafts during an evening technical lecture organized by the Institute of Marine Engineering, Science & Technology (IMarEST). Taking place on September 13th at the IMarEST’s London HQ, Thordon Bearings’ regional manager George Morrison, […]

C-Flex double end pivot bearing

The C-Flex bearing or pivot is a cylindrical, limited rotational bearing, with a high relative radial and axial stiffness which is available in low, medium, or high torsional spring rates. It is typically available for maximum deflection angles of +/-30, but various configurations are supplied upon request. Torsional stiffness ranges from .0003 Lb-In/degree to 7.8023 […]

Basics of plain bearings

Plain bearings are cylindrical sleeves that bear light to moderate radial loads. They slide radially or axially over shafts to allow rotary motion or linear motion (or sometimes both) of these loads. Plain bearings of all types are compact and lightweight with high strength-to-weight ratio. Plain bearings have none of the moving parts that rolling-element […]

Update on flexible-coupling considerations for OEM and plant designs

Couplings connect rotating shafts in equipment powered by electric motors and other drives. All transmit torque and angular velocity. Flexible variations compensate for misalignment. Many of the latter even address vibration and improve system dynamics. Design considerations include machine or installation construction and backlash, torsional stiffness, damping, inertia, torque ratings, maximum rpm, size, misalignments, ease […]

The sound of light: rotary servo table helps with 3D imaging

Edited by Mike Santora Optoacoustic tomography (OAT) is a technique for generating high-resolution images of biological tissue that scatters light waves, typically biological tissue. OAT systems create these images with pulses of dark red light that have a maximum duration of 50 nanoseconds. These pulses heat the tissue and cause it to expand launching ultrasound

Scanning performance of air bearings

Stefan Vorndran • PI (Physik Instrumente) L.P. Air bearings are common in scanning applications. Scanning involves moving either a work-piece or an optic at a constant velocity, while a reading or writing operation takes place. Such operations include printing and image-setting (writing) and imaging (reading). While the physical act of writing an image or capturing an […]
