DIN 705 Shape A Steel Set Collar, Without Set Screw

DIN 705 applies to set collars fitted with a hole on the side. It is designed for fitting a screw to securely fix a part on a shaft and prevent it from shifting. The shape A design provides for one threaded hole for diameters up to 70 mm and two holes for larger-diameter products.

They are positioned at an angle of 135 degrees to each other. Fasteners of this type are used in various mechanisms to improve their reliability.

Materials and specifications

Set collars of this type can be made from carbon steel, either plain or coated to extend service life. If the fastener is intended for use in a chemically aggressive environment or high humidity, it is made from A2 stainless steel. Acid-resistant steel can withstand corrosion for a long time and tolerates contact with chemically active substances.

Set collar specifications:

• Inner bore diameter — from 6 to 50 mm, selected according to the shaft diameter.
• Outer diameter of the product — from 12 to 80 mm.
• Thread diameter of the hole for the set screw — from M4 to M10.
• Set collar thickness — from 8 to 18 mm.

The products are available in a wide range of sizes, which makes it possible to select a suitable collar for various tasks.

Applications

The main application of these parts is in mechanical engineering. Set collars are used for assembling components of units and assemblies: they secure a part on a rotating shaft and prevent it from shifting. The set screw is inserted into the prepared hole and prevents the collar from moving. Products of this type are used in the automotive industry, heavy engineering, machine tool building, and other industries.

FLOK supplies DIN 705 shape A set collars in a wide range of sizes.
