Constant/Variable Rail

The layout of constant radii rail (CKR) corresponds to a partial section of a complete circle.
Variable radii rail (CVR) is a combination of variable radii and straight sections.

Standard radii: 150-200-250-300-400-500-600-700-800-900-1000 mm

The max angle (X) is dependent on the radius.
For curvilinear rails with variable radii, Y must be at least 70 mm.
Fixing holes (V) for countersunk head screws according to DIN 7991.
Fixing holes (C) for socket cap screws according to DIN 7984.
Treaded fixing holes (F).

Please indicate the precise rail layout and the desired hole pattern in a drawing. We recommend 80 mm on the extended length as a gage for the hole pattern.

Non-standard radii are possible as special products. For more information on rail layouts, radii and hole patterns, please contact Rollco.
