erection and construction of various works and structures. SUBSTANCE: guiding profile is produced from polymer material with bearing base and sliding layer to accommodate member contacting it and made of polymer material or having polymer coat. Sliding layer has thickness not less than 5.0 mcm with average roughness up to 5.0 mcm on side of working surface at least on part of length of guiding profile. Layer is manufactured by extrusion from melt of composition granulated in advance and containing polyethylene of high and medium density in ratio from 5:95 to 95:5 correspondingly and including 0.5-25.0 per cent by mass of silicon rubber. EFFECT: reduced effort needed to position member in profile, increased reliability of its movement if some section of it deviate from rectilinearity. 4 cl, 3 dwg |
