The linear guide rails and blocks come in two high-load and two ultrahigh-load capacity ranges. Single sections come in lengths to 4,000 mm, and matched sections accommodate longer runs.

A seal protects the ball bearings within the guide block and a grease fitting lets users add lubricant. Also available are side-mounted grease fittings, bellows, and scrapers. Low-noise Spacer Series SPG/SPS linear guide blocks have plastic spacers and greater grease volume to lower ball friction and noise.
