Shafting Low Support Rails
The AISI C-1018 steel LSRM shaft support is a low support rail with a reduced footprint, and 40% lower profile than other support rails. This is an excellent choice for applications requiring compact low shaft support. The standard length for LSRM type supports is 1200 mm. No coating Length tolerance +0 mm/3 mm.

• Available as cut to length options up to a max length of 3657 mm. Example: 1200 mm would be LSRM16-1200-SL • If standard mounting holes are required, specify low shaft rails with pre-drilled mounting holes by part number. Example: LSRM12PD. Hole sizes and spacings are shown in the table. • If other than standard hole spacing is required, please provide drawings with all dimensions, tolerances, and quantity. With or without mounting holes, low shaft rails will be supplied in 1200 mm lengths when ordered by part number.

Precision case hardened and ground shaft, plus an LSR steel support rail, effectively doubles the life of the shaft by allowing it to be turned over for a fresh surface when wear becomes evident. Both sides of the shaft are counterbored so the shaft may be rotated 180°, and rebolted for use on the new side. This guide is sold as a two-piece set; the shaft and support are not assembled. The guide is then bolted down through the top of the shaft to reduce installation time. The shafts are also available in 400 series stainless steel. Drilled through and counterbored shafts may not be suitable for all linear bearings. No coating
