How to calculate duty cycle and what it means for machine life

April 4, 2022 By Danielle Collins Leave a Comment

linear rails

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

March 31, 2022 By Miles Budimir Leave a Comment

automation

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

March 24, 2022 By Miles Budimir Leave a Comment

linear guides

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

March 5, 2022 By Danielle Collins Leave a Comment

surface texture and roughness

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

February 11, 2022 By Lisa Eitel Leave a Comment

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 […]

What are the benefits of six-row linear bearings

December 15, 2021 By Danielle Collins Leave a Comment

six-row linear bearing cutaway

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 […]
