China Rings Manufacturers, Suppliers, Factory

The DIN 7993A (RW type) steel wire retaining ring for shafts is made of 65Mn spring steel and is heat-treated to possess high elasticity and fatigue resistance. The surface is typically treated with blackening or phosphating. Its key feature lies in the use of circular cross-section steel wires bent into shape, which is installed in the shaft end groove and achieves axial locking through its own elastic retraction. Compared to flat wire retaining rings, the circular wire design causes less wear on the shaft groove and provides more uniform clamping force. This product is widely used in mechanical manufacturing, automotive gearboxes, machine tool spindles, and other scenarios where axial positioning and anti-detachment of bearings or transmission components are required.

Our factory specializes in producing carbon steel open type fixing rings (optical axis locking rings), which are processed with high-quality carbon steel precision turning. The surface can be treated with blackening, galvanizing, etc. The product is designed with an open mouth and equipped with screw locking, used for axial positioning and limiting of cylindrical components such as optical axes, guide columns, and screw rods. Easy to install, no need to drill holes on the shaft, and the position can be adjusted freely.
