A crossed roller bearing is a type of rotary bearing that uses cylindrical rollers arranged in a crisscross pattern, with each roller oriented at a 90 degree angle relative to the one adjacent to it. This arrangement allows crossed roller bearings to withstand radial, axial, and moment loads, so they can often replace dual-bearing arrangements, for […]

What are the key parameters to consider when sizing and selecting a rotary actuator?
Rotary actuators — and their counterparts, rotary stages and rotary indexing tables — are designed to move loads radially with high positioning accuracy. Similar to linear actuators, sizing a rotary actuator requires evaluating parameters such as torque, speed, and inertia, as well as ensuring the actuator can meet the application requirements for positioning the load, such […]
Dorner’s virtual showcase now open with nine product demonstrations
As industry professionals are still unable to visit Dorner in person due to trade show cancellations, Dorner is bringing the trade show to them! Dorner is hosting its own virtual showcase that includes nine demonstrations covering sanitary, automation and industrial applications. Each demonstration contains a video narrated by Dorner experts who point out features, benefits and […]
Wafer-handling machine maximizes performance with specially clamping belt-pulley and bushing assembly
In one recent machine redesign, Florida-based machine builder Hine Automation added precision engineered pulley-bushing assemblies to their SL-200C Vacuum Cassette-to-Cassette-Wafer Handling System for a boost in performance. This machine’s function is to transfer silicon wafers from a wafer cassette to a wafer process module under vacuum. The moves are commanded by computer controls. Hine Automation […]
Pallet-handling conveyors: Harnessing the power and safety of all-electric peripheral components
Pallet-handling conveyors optimize manufacturing, assembly, and testing processes by conveying product on workpiece pallets. The workpiece pallet provides consistent and stable conveying — regardless of the product’s current shape and future evolution down the line. By Kate Nadeau • mk North America Pallet-handling conveyor systems are reliable, durable, and highly intelligent systems that integrate and […]
What are rotary actuators and how do they differ from other rotary tables?
When we think about actuators, we typically think about linear actuators — devices that move loads in a straight line, driven by a screw, belt, or other mechanical power transmission device. But there also exists a class of actuators that provide rotary motion for positioning a load radially around a fixed axis. While these rotary […]
New integrated servo motors from Maxon feature IP65 protection
Maxon’s new IDX compact integrated servo gearmotor + drive combines a powerful, brushless EC-i motor and an EPOS4 positioning controller, which can be complemented with a maxon planetary gearhead when required. This integrated motor features high torque density, high efficiency, maintenance-free components, and a high-quality industrial housing providing IP65 protection. The IDX also features configurable […]
Podcast: Planar motors and linear transfer systems in action (addressing COVID and more)
In a recent podcast interview, we got the chance to talk with Jeff Johnson of Beckhoff Automation about linear-motor conveyors (also called intelligent transport systems) as well as the planar-motor system from Beckhoff called the XPlanar. Listen in: Design World · Planar motors and linear transfer systems in action! Beckhoff engineer Jeff Johnson explains […]
What is a zero pressure accumulation conveyor?
A common function of a conveyer system is to accumulate products — in other words, to stop them from moving along the conveyor to create a buffer, establish a queue, or smooth out differences in material movement between upstream and downstream operations. But traditional accumulation methods allow products to bump into each other and stack up […]
Micro motors give robotic hand a boost
Among the changes to small motor design over the years has been the use of powerful rare-earth magnets to increase power density, making for smaller and more powerful motors. These motors are finding their way into medical devices, robotics, as well as the intersection of these two. Case in point; a robotic glove. Ironhand from […]
