The expanded line of NB SGL slide guides from NB Corp. of America are high-precision linear bearings with low friction and non-stick (and non-slip) mechanisms for smooth linear motion … even under high loads.
The SGL Slide Guides are 160 mm to 3,000 mm long. Six types of blocks are available depending on the mounting space and target mounting method. Three accuracy grades let design engineers tailor the slide guide to the application’s required level of position precision positioning.
The number of tracking grooves for ball elements or rows of rollers varies by type of glide and width ranges. There are retained and non-retained ball elements.
A fiber sheet in SGL linear slide guides ensures long-life lubrication with durable performance even when the slide is subject to harsh conditions such as dust that tends to absorb lubricant. Embedded in a block body, this fiber sheet has no effect on overall linear-carriage (block) length. Plus the fiber sheet requires no changes in the linear slide’s mounting — so direct replacement of existing linear slides is possible.
Detailed drawings and tables provide dimensional and mechanical information … and 3D CAD files are available as well.
The SGL slide guide is a four-row, two-point contact mechanism. That means it has high self-centering characteristics as well as high load capacity due to relatively large ball elements. In addition, the slide guide easily resists debris and dust ingress with side-seals and under seals. The slide guide is also available in stainless steel for corrosive or otherwise challenging machine installations.
SGL slide-guide double side seal: With this option, the prevention against dust is greatly improved. This option is suitable for applications where bellows or covers can’t fit over the slide guide system.
SGL slide-guide scraper option: When the application environment has unfavorable foreign matter or debris such as welding splatter or cutting debris, the scraper option provides an effective protective measure for the slide guide system.
Joined rails are available for SGL in standard grade variations as well as high-grade offerings with standard preload.
