If you work with linear ball or roller bearings, you’re familiar with the L10 bearing life equation, which states that bearing life is equal to the bearing’s rated dynamic load capacity, divided by the applied load, raised to a power of 3 (for ball elements) or 10/3 (for roller elements). Introduced in 1947 by Gustaf […]
What makes a linear guide suitable for high temperature use?
For most recirculating ball and roller linear guides, the allowable operating temperature range is -10° to 80° C, with some configurations rated up to 100° C for brief periods. But not all applications fall within this temperature range, and each component in the linear bearing assembly (housing, rail, balls, seals, etc.) has a different maximum […]
New Compact Linear Bushing (CLB) from Samick
The new Compact Linear Bushing (CLB) by SAMICK, a specialist in linear bearings, is gaining popularity in the market as the company expands its product offering for customers. SAMICK’s CLB is a linear ball bearing that conforms to the ISO 10285 standard, providing customers with a low-cost, compact design for easy integration into new or […]
What you need to know about corrosion-resistant linear guides
Recirculating ball and roller guides are the backbone of many automation processes and machines, thanks to their high running accuracy, good rigidity, and excellent load capacities — characteristics made possible by the use of high-strength AISI/ASTM 52100 chrome steel (commonly referred to as bearing steel) for the load-bearing parts. But because bearing steel isn’t corrosion-resistant, […]
New profiled linear guideways from SCHNEEBERGER handle loads up to 150 tons
SCHNEEBERGER Inc. has expanded its MONORAIL MR profiled linear guideway series with its new MR 30 MONORAIL 30-mm rail and cross roller cartridge. The MONORAIL MR series moves especially heavy workpieces of up to 150 tons — with extreme accuracy — in milling, turning, drilling, or grinding machines. The new MR 30, along with the […]

Mechanical properties of materials: stiffness and deflection
In a previous post, we looked at the stress-strain curve and its relationship to various aspects of material strength — tensile strength, yield strength, and fracture strength, for example. And while we often think of materials and structures in terms of strength, technically, “strength” is a measure of how much force a material can withstand […]
New linear motion kits from Ewellix extend industrial robot capabilities
Ewellix, formerly SKF Motion Technologies, has launched a new series of linear motion modules designed to increase significantly the capability of small industrial automation robots and cobots. The company’s new LIFTKIT and SLIDEKIT can extend the reach and mobility of standard robots without the need for expensive upgrades or complex accessories and programming. The new […]
