Rotor Clip DHO-80ST N Pd Metric Internal Snap Ring 80mm

Product Description

The ROTOR CLIP DHO-80ST N PD is a metric internal snap retaining ring engineered for 80mm bore applications. Made from spring steel grade 1060/1090 with a phosphate finish, it seats into a machined internal groove to retain shafts, bearings, and assemblies against axial movement. The ring measures 85.5mm free outer diameter, 2.5mm ring thickness, with a groove width of 2.65mm and a groove depth of 1.75mm. Groove diameter tolerance runs 0.000 to 0.350mm, and ring thickness tolerance is -0.07mm. It conforms to DIN 472 and ISO 13485:2016 standards. Machinists, maintenance technicians, and mechanical assemblers install this ring in industrial and OEM equipment where reliable axial retention is required.

This retaining ring is suited for residential and commercial mechanical assemblies where an internal groove retains a component inside a bore. Typical applications include gearboxes, pumps, motors, and hydraulic cylinders with an 80mm internal bore. The phosphate finish provides baseline corrosion resistance in light-duty environments. This ring ships in a package quantity of five, making it a practical option for service shops and assembly lines requiring small-quantity restocking.

Key Features

• 80mm bore diameter with a groove diameter tolerance of 0.000 to 0.350mm for precise fitment
• Spring steel grade 1060/1090 construction for consistent snap-ring tension and durability
• Phosphate finish for corrosion and wear resistance in industrial environments
• Thrust load capacity of 120 kN at the ring and 74.60 kN at the groove
• Conforms to DIN 472 and ISO 13485:2016 dimensional standards
• Ring thickness tolerance held to -0.07mm for consistent groove seating

Compatibility

Designed as an OEM-style metric internal snap retaining ring for 80mm bore applications conforming to DIN 472 specifications.

Installation Notes

Installation and removal require snap-ring pliers sized for internal rings; standard slip-joint or external-ring pliers are not appropriate substitutes. Depower or de-energize any machinery and release hydraulic or pneumatic pressure before servicing the groove or ring. Confirm groove dimensions match the ring specifications before installation to avoid under-seating or groove damage. Inspect the groove for burrs or contamination that could prevent full ring seating.
