Product Description

When bolted down, the China Stainless Steel DIN 6798A Conical Spring Washer by Wanluo flattens slightly to generate continuous and stable restoring elastic force, effectively compensating for thread clearance, thermal expansion gaps and stress relaxation. It solves common fastening failures such as bolt loosening, poor fitting and uneven compression caused by equipment vibration and alternating loads, ideal for precision leveling and high-reliability anti-loosening assembly scenarios.

Dimensional Construction Property & Heat Forging Machining Craft

DIN 6798A conical washers adopt high-purity spring steel and premium stainless steel materials, processed by integral precision stamping, curved surface one-piece forming and strict heat treatment toughening. The standard single conical tapered surface features uniform radian and consistent elastic coefficient, ensuring even stress distribution after compression and stable elastic recovery without deviation. The smooth burr-free upper and lower surfaces perfectly fit bolt heads and workpiece planes, achieving automatic micro-leveling during locking to offset minor assembly tilt and uneven contact gaps. The overall structure boasts high hardness and strong fatigue resistance, resisting permanent deformation and elastic failure after thousands of compression and vibration cycles. Strict dimensional tolerance control guarantees perfect matching with standard metric bolts, enabling standardized and efficient assembly for industrial production.

Unique Product Traits & Engineering Scenario Matching Guide

1. Unique single conical self-leveling design automatically compensates for uneven assembly gaps and minor workpiece tilt, ensuring full and uniform fitting between bolt and workpiece, avoiding local stress concentration and improving overall assembly flatness.

2. Continuous elastic tension output effectively resists vibration and alternating load impact, automatically compensating for thread gap expansion caused by temperature change and mechanical operation, preventing bolt loosening and improving connection stability.

3. Superior fatigue resistance compared with ordinary DIN 127 spring washers, with stable elastic performance after long-term repeated compression, no elastic failure or relaxation, suitable for long-cycle continuous operation equipment.

4. Smooth integrated forming structure will not scratch or dent precision workpiece surfaces, combining surface protection, leveling correction and anti-loosening locking functions into one, simplifying assembly combination and improving installation efficiency.

5. Multiple material and surface treatment options adapt to diverse working environments, widely used in precision instruments, automation equipment, automotive parts, electrical facilities and general mechanical anti-loosening assembly scenarios.

FAQ

Q1: What is the difference between Stainless Steel DIN 6798A Conical Spring Washers and ordinary spring washers?

A1: DIN 127 split spring washers rely on split biting for anti-loosening and easily fatigue under long vibration; DIN 6798A adopts integral conical elastic structure with self-leveling function, providing more stable elastic pre-tightening force, no workpiece damage, better vibration resistance and longer service life.

Q2: What is the main function of DIN 6798A conical washers?

A2: It focuses on precise leveling and elastic anti-loosening. It compensates for assembly errors and thread gaps, maintains consistent bolt pre-tightening force, and prevents loosening caused by vibration, temperature variation and stress relaxation.

Q3: Can DIN 6798A be used with flat washers?

A3: Yes. It can be used alone for lightweight anti-loosening assembly or matched with DIN 125 flat washers for dual protection, suitable for medium-load and high-flatness assembly requirements.

Q4: Will the conical structure deform after long-term compression?

A4: Our products undergo professional integral heat treatment and elastic calibration, with high structural toughness and compression resistance. No permanent deformation or elastic fatigue occurs under standard working loads, ensuring long-term stable locking effect.

Q5: Are customized non-standard specifications available?

A5: Yes. We support customizing special taper height, thickened reinforcement, non-standard outer diameter and high anti-corrosion surface treatment to meet personalized precision assembly requirements.
