Axle washer | A2 | DIN 1440
Do you need a washer that provides a precise and secure fit for pin or hinge joints? The clevis washer, also known as a plain washer for clevis pins DIN 1440 in A2 stainless steel, is designed to minimize play and distribute the load evenly in mechanical joints. Thanks to its A2 (AISI 304) stainless steel material, the washer is resistant to corrosion in most indoor and outdoor environments. The washer is thicker and has a tighter inner diameter than a standard washer, making it particularly suitable for split pins, bolts, and clevis joint assemblies.
AREA OF APPLICATION
Perfect for securing and reinforcing clevis joints, articulated arms, machine parts, and link assemblies in mechanics, construction, and the automotive industry. The tight fit against the pin prevents unnecessary wear and movement in the joint, and the smooth contact surface protects components from deformation. Common applications include machine building, agricultural machinery, construction equipment, hydraulic systems, and moving links in industrial structures. Easy to install together with a split pin or locking pin and requires minimal maintenance even during frequent operation.

FREQUENTLY ASKED QUESTIONS (FAQ)
What distinguishes a clevis washer according to DIN 1440 from a standard plain washer (DIN 125)?
DIN 1440 has significantly tighter tolerances for the inner diameter and is manufactured in a thicker design than standard washers. It is designed to fit precisely over shafts, clevis pins, and cylindrical bolts with minimal play, which prevents the washer from tilting or wearing unevenly during mechanical movement.
What is the technical function of DIN 1440 for hinge joints and split pin assemblies?
The washer acts as a hard, smooth contact surface between the rotating hinge element and the locking element (e.g., a split pin DIN 94 or circlip). It distributes axial forces evenly over the entire surface, protects the fastener from wear, and ensures the locking element remains securely in place without the risk of being cut through by mechanical vibrations.
Why is A2 / AISI 304 stainless steel a good choice for clevis washers?
A2 stainless steel (AISI 304 / 1.4301) provides high mechanical strength combined with very good corrosion protection in outdoor environments, damp areas, and industrial applications. The material retains its properties under continuous mechanical load and withstands weather and wind without rusting or discoloring.
