Tribology is the study and application of the principles of friction, lubrication, and wear between two surfaces in relative motion. In linear bearing systems, those two surfaces are the bearing element and the guide raceway. Friction and wear The … [Read More...]

Selecting shafts for linear bearings: two things you need to know
In a round shaft linear bearing system, the shaft acts as the inner raceway of the bearing and plays a significant role in the wear and life of the system. Both recirculating and plain … [Read More...]
What is a gimbal and how is it used?
In simple terms, a gimbal is a pivoting platform that allows an object to rotate around one or more axes. They're often found in photography and videography applications to stabilize cameras, as well … [Read More...]
Take the burden out of managing misalignment in linear motion systems
No one wants a linear bearing to fail prematurely. While many factors can threaten a bearing’s expected life, designers of industrial machines must especially guard against alignment errors between … [Read More...]
How do roller pillow blocks compare with traditional round shaft bearings?
Round shaft guides are typically used with plain (composite, plastic, or bronze) or recirculating ball style linear bearings. But another type of round shaft bearing — referred to as a roller block or … [Read More...]
Belt-driven electric actuators from IMI Norgren offer precise control
A new line of belt-driven electric actuators from IMI Norgren is designed to meet the force and extreme loading requirements for machine builders and plant engineers looking for an alternative to … [Read More...]
What are roller chain wear indicators?
Rollers chains, as a mechanical power transmission method, and like any mechanical system, are subject to wear over time and with continued use. Just how much it wears depends on a number of factors … [Read More...]
Tribology basics for linear bearings
Tribology is the study and application of the principles of friction, lubrication, and wear between two surfaces in relative motion. In linear bearing systems, those two surfaces are the bearing … [Read More...]
What are hexapod robots (also referred to as Stewart platforms)?
Multi-axis systems can be designed and built with either serial kinematics or parallel kinematics. In systems built on the principle of serial kinematics, one axis sits on top of another axis, and … [Read More...]
What are some options for quieter chain operation?
Chain and sprocket drives are a traditional power transmission/motion technique. In general such drives tend to perform admirably well in harsh environments and feature high wear resistance and … [Read More...]
What is a Cartesian robot?
We've written several articles on this site about Cartesian robots, but let’s take a step back and define exactly what makes a robot a Cartesian robot, as opposed to another type of robot or … [Read More...]
What is a direct drive motor?
A direct drive motor is any motor — rotary or linear — in which the load is connected directly to the motor, without mechanical transmission elements such as gearboxes or belt and pulley systems. In … [Read More...]
Low-profile linear stepper motor stage from H2W Technologies
The LSS-016-04-006-01A-ME is one of a revolutionary new series of low-profile linear stepper motor positioning stages that integrates an absolute linear encoder and a single-axis linear stepper motor … [Read More...]
SKF LLT profile rail guides designed to suit a wide range of applications
SKF LLT profile rail guides from SKF Motion Technologies, Inc. have been uniquely designed to deliver smooth running performance, high precision and accuracy, and long service life with minimal … [Read More...]
How does the number of stator phases affect stepper motor performance?
Stepper motors move in discrete steps when current is applied to coils in the stator. The size of the step is determined, in part, by the number of phases in the stator. In general, the … [Read More...]
SUPERWURM worm farm uses motion components from igus
One automated worm farm in Germany to breed and grow worms includes machines to continuously lift, transport, release, stack, drill, and spray giant red worms called dendrobena. Duren-based SUPERWURM … [Read More...]
