Crossed-roller slides

What’s the difference between dynamic load capacity and static load capacity?

★ By Danielle Collins Leave a Comment

dynamic load capacity

Rolling element linear bearings, such as round shafts and bushings, profiled rail guides, crossed roller slides, and even ball screws, have two load capacity specifications — dynamic load capacity and static load capacity — which are based on different operating parameters and performance criteria and are independent of each other. To accurately size and select a […]

Gallery: Crossed-roller slide variations and uses

★ By Lisa Eitel Leave a Comment

Precision rail guides known as crossed-roller guides (also called crossed roller slides, linear bearings, or ways) are linear-motion load supports that incorporate arrays of cylindrical roller bearings for the reduction of friction. These crossed-roller slides contain the rollers between solid twin guide bars (usually made of through-hardened tool steel) cut with V-shaped grooves that are […]

When to consider crossed roller slides

★ By Danielle Collins Leave a Comment

crossed roller slides

When an application requires a linear guide with high load capacity, high stiffness, and good travel accuracy, the range of suitable products is typically narrowed down to two designs: recirculating linear guides and crossed roller slides. Where recirculating linear guides use balls to support the load, crossed roller slides use rollers. The rollers ride in […]

What are the differences between plain and rolling linear guides?

★ By Danielle Collins Leave a Comment

boxway

A linear guide (or linear bearing) is a mechanical element that allows relative motion between two surfaces, with one surface supporting the other, and minimum friction between the two. There are two basic types of linear guides: plain and rolling element. While their general function is the same, their design and performance differ significantly. Linear […]

What is a crossed roller slide?

★ By Danielle Collins 1 Comment

crossed roller slide

As their name suggests, crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground. The term “crossed” refers to the fact that the rollers are arranged in a crisscross […]

How to pick dovetail slides for durable designs

★ By Lisa Eitel Leave a Comment

Gilman-application-dovetail

Christopher J Hetzer, CEO, Gilman USA The geometry of dovetail slides improves the precision of in-line movements for some machines. Dovetail-slide assemblies go into applications that need accurate linear strokes even under complex loading or nonstandard mounting arrangements. Like other linear-motion devices, they have a stationary rail (the base) and a moving carriage (the saddle). […]

How Seals Extend the Life of Linear Systems

★ By Danielle Collins 7 Comments

When selecting a linear system – ball screw, linear guide, or actuator – most of the focus is on application data such as load, speed, travel, and duty cycle. But there’s another factor that should be considered, especially for technically demanding applications or harsh environments. That factor is sealing. How are the bearings protected against […]
