HepcoMotion is launching LBG linear ball guides with a corrosion-resistant coating. This cost-effective, hard-chrome alternative to stainless steel is available for all rails and bearing blocks in the LBG linear ball guide product programme. It provides a good degree of corrosion resistance for applications where moisture or contaminants could cause surface pitting. The introduction of this variation also opens up the market for this product in clean rooms where previously stainless steel was the only suitable option.
High quality, good accuracy and exceptional rigidity characterise the LBG range. Its basis is a four-row, angular-contact ball track that has numerous benefits. These include low friction and reduced differential slip, high load-carrying capacity in four directions and installation compliance. It also compensates for minor errors on the mounting surface without compromising performance.
A felt wiper within the bearing block aids lubrication, maintaining a positive oil film on the bearing contact surfaces. Extended life and increased maintenance intervals are achieved by having the correct amount of lubricant at the contact faces.
LBG corrosion-resistant, hard-chrome plated linear guide rails are supplied up to 4m in length and in matched sets to ensure that, even with the addition of the hard-chrome coating, the preload of the block on the rail is consistent. A stock range is available to cover the majority of automation requirements. However, a wider combination of preloads and grades can be supplied to suit the specific needs of individual applications.
