NB Corporation’s EXRAIL linear guide has more rollers in less space than other linear bearings, which increases load capacity and disperses the load more evenly. It has longer rollers for greater contact surface and less contact pressure. In comparison to presently available linear guides, the EXRAIL slide guide provides smoother movement. It uses multiple small […]
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 […]
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 […]
Full extension telescoping rails feature smooth sliding
LM76 has added a new series of 100% extension rails to their extensive product line of linear motion components and complete linear motion systems. The exclusive distributor of SAIBO Linear Motion Systems in the US, LM76, is now offering the SAIBO TDB28 and TDB43 series of Telescoping Extension Rails. Stroke lengths (extension) are 100% of […]
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 […]
