DIN 703 Setting Ring with Screw Socket, Steel, Stainless

The DIN 703 standard covers the manufacture of adjustable-type setting rings fitted with a threaded hole for installing a screw. The main purpose of setting rings is to provide secure fixation of various components and fixtures on a shaft during rotation; such fasteners increase the reliability of the assembly.

The product has two holes for screwing in screws, positioned at an angle of 125 degrees to each other. Such fasteners are used in many branches of mechanical engineering.

Materials

Setting rings can be made from carbon steel of various property classes. To extend service life and improve corrosion resistance, they are coated with zinc applied by electroplating. Products with enhanced corrosion resistance are also made from stainless steel A2 and A4. Such rings are used together with set screws manufactured to DIN 914.

The products have the following set of technical characteristics:

• The outer diameter of the setting ring can range from 56 to 160 mm.
• The inner diameter is from 24 to 120 mm.
• The ring height can range from 2 to 32 mm.
• Holes with thread diameters from M10 to M12 are used for mounting on the shaft.

Application options

Setting rings are used in automotive manufacturing, instrument engineering, machine-tool building, and in heavy engineering for assembling various equipment. FLOK supplies this product in wholesale batches of any size.
