Profile Guide Rails are linear motion bearings which incorporate a linear guides rail (inner race) with precision ground grooves along the entire length of rails, combined with a precision machined carriage block (outer race) with matched rolling elements tracking the inner race grooves. This combination of precision grooves and matched carriage provides for high-load capacities, smooth motion, long predictable life in a small compact work envelope.

SEB Series is our small lightweight series with overall height of only 6mm and rail width of 5 mm. This light series uses a 2-row, 4-point contact configuration to provide static capacities from 720 N to 15700 N.

The SEB Series offeres unique features to help you design the correct part of your motion system.

Standard length blocks as well as a long block for added foot print and increased capaciies.
Three choices of pre-load, (Standard, T0 and T1)
Carbon steel as well as Stainless Steel options on both rail and carriages.
Standard precision and high precision accuracy classes.
Tapped rail-mounting holes.

Specialty Motions Inc. also offers a wide series ("W") in the light weight catagory starting with a rail height of 9 mm to 16 mm with widths from 14mm to 42 mm. The same design options apply to this series with stainless steel, tapped rail-mounting , pre-load, accuracy classes and block lengths to select.

For Ultra high end applications requiring extreme load capacity, accuracy and rigidity in a compact package, SMI offers the SER Series with 2-row, recirculating crossed roller profile rails in both a standard width and double wide series ("W") and two accuracy classes.

The SERS Series is all stainless steel providing excellent corrosion resistance and thermal characteristice as well is
ideal for clean room and vacume applications.
The SGL Series is high rigidity, 4-row, 2-point contact series with flanged and non-flanged carriages, extra long blocks for increased capcities, three levels of pre-load and three levels of accuracy. Maximum rail lengths for this series are from 1000 to 3000 mm with system heights from 24mm to 48mm, capacities range from 5000 N to 37,700 N.
