Linear ball guide assemblies now available with hard chrome coatings
04 October 2010
The LBG linear ball guide from HepcoMotion is now available with a corrosion resistant coating. This hard chrome alternative is available for all rails and bearing blocks in this product programme and provides a good degree of corrosion resistance for applications where moisture or contaminants could cause surface pitting. The new coating enables this product to be used in clean rooms where previously stainless steel was the only suitable option.
The LBG is based on a four row angular contact ball track that provides 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 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 pre-load of the block on the rail is consistent. A wide combination of pre-loads and grades can be supplied to suit the specific needs of individual applications.
