The DS4/6 Series is Kollmorgen’s most versatile and modular line of positioning tables, offering design flexibility and a wide variety of configurations for high-precision positioning applications. The DS4/6 series is available in single and multi-axis configurations, including XY, XZ, XYZ and Cartesian arrangements. The tables are driven by a precision ball screw (with 5, 10 […]
What are boxway slides and where are they used?
Recirculating linear guides get significant media attention, thanks to their versatility and wide range of uses. But linear guides based on sliding contact — namely boxway and dovetail slides — are often the bearings of choice for applications that call for high load capacity, extreme stiffness, and excellent vibration damping characteristics. Boxway slides are a type […]
Linear guides with more rollers feature high load capacities
NB Corporation’s EXRAIL linear guide has more rollers in less space than other linear bearings, which increases load capacity and disperses the load more evenly. It has longer rollers for greater contact surface and less contact pressure. In comparison to presently available linear guides, the EXRAIL slide guide provides smoother movement. It uses multiple small […]
Motion basics: How to define roll, pitch, and yaw for linear systems
Linear guides and systems — including Cartesian robots, gantry systems, and XY tables — are typically subjected to both linear forces due to downward, upward, and side loads and rotational forces due to overhung loads. Rotational forces — also referred to as moment forces — are typically defined as roll, pitch, and yaw, based on […]
When do you need to consider thermal expansion in linear guide systems?
Most materials used in linear systems have a positive coefficient of linear thermal expansion — that is, when their temperature is increased, they expand in length, and when their temperature is decreased, they contract in length. One notable exception is Kevlar, the aramid from DuPont, which is sometimes used for tensile cords in toothed belts. […]
Slide ways for precise motion control
NB Slide Ways are non-recirculating linear motion bearings used primarily in optical and measurement equipment where high precision movement is required. The SV style consists of two roller cages with precision rollers in a cross arrangement and four rails with V-shaped raceways. The SVW has one rail with V-shaped grooves on both sides and two […]
Industry’s smallest slide with anti-cage creep technology
PM introduces the next generation of miniature slides: the MSR. This product has been developed according to the rising demand for smaller, compact linear slides for use in dynamic and accurate applications. The miniature slides are developed for increased output in micro-assembly machines and pick-and-place machines. The MSR miniature slide can also be used in […]
IMScompact: Guidance and measuring system requires no additional space
With its sensor system completely integrated in the ball runner block, Bosch Rexroth’s new IMScompact integrated measuring system determines the exact position with a high repetition accuracy of ±1 μm. IMScompact enhances the range of linear guides and is available in sizes 15, 20 and 25, making the measuring system for ball rail systems a […]
New flanged linear bushings available from Samick
Manufacturers are faced with the enormous challenge of minimizing risks in their manufacturing processes while at the same time lowering costs and improving product quality. Flanged linear bushings from SAMICK can meet these customer requirements. Whereas standard linear bushings must be used in combination with casings, flanged linear bushings are directly mounted onto the housing […]
FDA-compliant off-the-shelf linear motion components for urgently needed medical products
In dealing with the COVID-19 pandemic many companies have volunteered or been requested to produce urgently needed medical products such as masks, gowns, and ventilators. Tooling up quickly to produce medical grade products for some companies can bring challenges. In addition to needing FDA-compliant materials that will be used in the actual masks, gowns, and […]
