The top 10 Linear Motion Tips articles of 2015
With the range of technologies, designs, and options available for linear motion components, ploughing through the alternatives and making the best decision takes more time and resources than many designers and engineers are able to expend on any individual component. Looking back at the top 10 most-read Linear Motion Tips articles of 2015 confirms this situation. From primers on […]
Ball rail systems: twice the service life and high travel accuracy
The patented entry zone of the new BSHP ball runner blocks from Rexroth improves travel accuracy and work piece quality while greatly increasing load capacities and service life. These runner blocks are available in most sizes, versions, and accuracy classes. BSHP ball runner blocks are 100% interchangeable into existing profiled rail applications using the same […]
Bearing load capacity explained
There are two load capacity specifications for recirculating linear guides and ball screws—static load capacity and dynamic load capacity. Most engineers are familiar with dynamic load capacity, since this is the value used to calculate bearing life. But it’s also important to consider the component’s static load capacity in order to avoid premature bearing failure. Here’s a […]
Bearing lubricant: Choosing between grease and oil
Lack of bearing lubrication is generally regarded as the number one cause of linear-bearing failure. For recirculating linear bearings such as profiled rail guides and ball screws, lubrication separates the bearings (ball or roller) from the raceways, minimizes friction and wear, dissipates heat, and prevents corrosion. It also promotes smooth running of the seals and […]
Linear motion tips for food and beverage applications
It’s not hard to understand why applications in the food and beverage industry are especially challenging for linear motion systems. Food processing and packaging equipment must simultaneously meet high throughput requirements and withstand harsh environments, while safely handling and processing products which are at constant risk for spoilage or dangerous contamination caused by environmental factors or improper handling. Add to this […]
Don’t ignore these three things when mounting linear guides
Linear rail guides are designed for applications that call for precise motion with high load-bearing capability. But improper mounting can add unnecessary loads, reduce life, and undermine the inherent travel accuracy of the linear guide system. Understanding and following the three mounting specifications described below will help ensure your installation achieves the desired accuracy and doesn’t succumb […]
Breaking down linear bearing construction
As with most complex products or systems, specifying and applying profiled rail bearings doesn’t require that you know every detail of linear bearing construction. But having a basic understanding of the various design types and geometries can help you choose a product that enhances, rather than detracts from, the performance of your machine—especially in applications that […]
Nook Industries offers caged ball profiled rails for linear guidance
Nook Industries, a leading innovator of linear motion components and systems, introduces caged ball profile rails for linear guidance. Caged ball chains provide reduced friction and lower noise levels and prevent the bearings from making incidental contact. An industry leader for more than 40 years, Nook’s new line improves on more traditional designs with lubrication advantages, […]
Miniature linear ball rails from Nook Industries for high-speed running capacity
Nook Industries, a leading innovator of linear motion components and systems, has launched a new miniature linear ball rail ideally suited for high-speed, belt-driven mechanisms and carrier designs as well as automation linkage between stations. Offered in three accuracy grades, Precision (P), High (H) and Normal (N), these miniature linear ball rails provide significant maintenance […]
