Rollon’s updated digital platform includes personalized product selector
Rollon, a leading manufacturer of linear motion systems, guides, linear actuators and gantry systems, has unveiled a new digital tool to help engineers design equipment and systems more efficiently. The new ecosystem consists of two core elements: a redesigned corporate website and myRollon — a tool that personalizes product selection. The website has been expanded […]
How to calculate duty cycle and what it means for machine life
Determining the life of a linear system that uses balls or rollers is relatively straightforward, thanks to the L10 bearing life equation, which gives life in meters of travel (for linear bearings) or revolutions (for screws). And for plain bearings and lead screws, manufacturers typically use the bearing’s PV value and operating conditions to provide an […]
Pandemic impacts linear motion component manufacturing, applications
Linear motion components include everything from various types of linear actuators to linear guides, slides and ways, and a host of components in between. One thing they all have in common is that their development and production are influenced by both technological trends as well as broader market forces. One of those forces is has […]
Miniature linear guides for mounting in tight spaces
IKO has expanded its LWL family of miniature guides with the addition of its newest LWLF2 linear motion rolling guide, which addresses the demand for device miniaturization with a compact, lightweight design that makes mounting easy in tight spaces. The new LWLF2 features the same ultra-small 2.5-mm height dimension as its predecessor, the LWL1. It’s […]
Linear bearing basics: Surface roughness, texture, and finish
One of the factors to consider when selecting shafts for linear bearings is surface roughness, which describes the microscopic asperities, or peaks, and valleys present on a material’s surface. But surface roughness is an important specification for all types of linear guides and screws — whether plain or recirculating, round shaft or profiled rail, ball […]
New LMHB linear ball bushing can press fit into assemblies
THK America Inc. now offers a type LMHB linear bushing for linear-motion applications. This linear bushing is press-fit into moving elements of linear motion axes to allow smooth traversal of round shaft. The THK LMHB linear bushing achieves smooth and silent motion thanks to the spring effect provided by curved metal plates within the assembly […]
Linear rails from Rollon simplify design of high-performance automated systems
Rollon has upgraded its Telerace family of linear rails to help designers simplify projects and enhance the efficiency of automated systems. Two Telerace families of cold-drawn steel rails now feature induction hardened and ground raceways along with double-row ball bearings for greater load handling capability, longer life and reduced maintenance requirements. The newly enhanced rail […]
Nook Industries sells family business to Altra Industrial Motion Corp.
Nook Industries, a leader in US engineered linear motion products and solutions, announced today that it has sold the family-owned business to Braintree, Massachusetts-based Altra Industrial Motion Corp. (Nasdaq: AIMC), a leading global manufacturer and supplier of motion control, power transmission and automation products. The Nook business, which will be integrated into Altra’s Thomson operating […]
What are the benefits of six-row linear bearings
The most common types of recirculating linear bearings use four rows of balls — two on each side of the bearing block — to provide good load capacity and rigidity. But the four-row design means that when radial (downward or liftoff) or lateral (side) loads are applied, only two rows of balls are engaged to support […]
