Whether guiding, adjusting, positioning or moving uniformly, the requirements for linear movement sequences are as diverse as the possible solutions. RK Rose+krieger offers three small linear units especially for precise manual adjustment.
Whether manual or driven single-tube, two-tube or profile axes, with roller or recirculating ball guides, combined with toothed belt or spindle drive – the linear technology portfolio from RK Rose+krieger for profile, linear and connection technology is suitable for almost every application correct linear unit ready. The spectrum includes linear movement components for occasional manual adjustment as well as for frequent movement and highly dynamic positioning in continuous use. The small spindle-driven and manually adjustable linear axes of the RK Compact, RK LightUnit and PLM types are particularly suitable for use with low torques and light weights.
Weight-reduced single-tube linear axis
The spindle-driven linear axis RK LightUnit was developed for easy adjustment by hand. It has an aluminum spindle and plastic plain bearings. These ensure a weight-reduced design so that the linear axis can be moved without much effort. An elastic plastic sealing lip protects the spindle. The single-tube linear axis is available in size 30 for a maximum stroke of up to 920 mm.
Flat short-stroke linear axis
The RK Compact is a flat short-stroke linear axis for the occasional adjustment of small loads with short strokes. It has an ideal ratio in terms of torque absorption and installation dimensions and is particularly suitable for small installation spaces due to its compact size. The RK Compact is available from stock in size 30 with standard strokes of 10, 20, 30 and 50 mm. The control strokes for sizes 50, 80 and 120 are 25, 50, 75 and 100 mm. All units with these strokes are ready for delivery within 48 hours. “On request, however, larger strokes of up to 130 mm (size 30) or 400 mm (all other sizes) are also available – these custom-made products only require a little more time,” says Tim Hallau, product manager for linear technology at RK Rose+krieger. Optionally, the axis can also be delivered as a pure sliding guide without a spindle drive.
Profile linear axis for light loads
The PLM type linear unit in sizes 20 and 40×20 is available for customer-specific strokes up to 855 mm. Their maximum strokes are significantly longer than those of the RK Compact. The special thing about the small linear unit is the steel band cover on the drive spindle to protect it from contamination. The linear axis is also available as a pure sliding guide without a spindle drive.
