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 […]
Ball + roller guides
What are rail brakes and when should you use them?
The servo and stepper motors that drive linear motion systems often include a braking function, or, in the case of stepper motors, detent torque that helps prevent the motor (and, therefore, the load) from moving when powered off. But in some applications, a secondary brake is required — either to provide redundancy and meet safety requirements […]
What are some alternatives to L10 bearing life?
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, […]
Thomson introduces online quote tool for customized 60 Case shafting and hardened pins

By providing real-time pricing and instant access to lead times for chosen products, Thomson’s intuitive, self-service tool allows designers […]
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 […]
What are needle roller linear bearings?
You might be familiar with rotary needle roller bearings (often referred to as simply needle roller bearings) which are used extensively in automotive and industrial power transmission applications due to their compact size and high load-carrying capability. But did you know that some linear bearings also use needle rollers? For linear bearings, needle rollers were […]
