Technical Specifications of the 60×82×7/10 Standard Hydraulic DKB Type Dustproof Wiper Oil Seal

The 60×82×7/10 Standard Hydraulic DKB Type Dustproof Wiper Oil Seal is engineered to provide superior protection for hydraulic cylinder rods. Its designation breaks down as follows:

• 60 mm: Inner diameter (rod diameter).
• 82 mm: Outer diameter (bore diameter).
• 7/10 mm: Axial height (7 mm for the primary sealing lip, 10 mm for the total height including the metal casing).

The "DKB Type" refers to its robust design, featuring a double-lip construction and an integrated metal case. This configuration offers exceptional scraping action against contaminants while maintaining a stable fit within the housing.

Material Properties and Performance Parameters

Typically manufactured from high-quality NBR (Nitrile Butadiene Rubber) or PU (Polyurethane) for the sealing lip, combined with a durable steel or stainless steel casing, the seal provides excellent resistance to wear, hydraulic fluids, and environmental aggressors.

Manufacturing Process Flow of DKB Type Wiper Oil Seals

The production of a high-performance seal like the 60×82×7/10 Standard Hydraulic DKB Type Dustproof Wiper Oil Seal involves a meticulous multi-stage process, ensuring precision, material integrity, and adherence to stringent quality standards.

Schematic Process Steps:

1. 1. Material Selection & Preparation: Sourcing of certified raw materials (e.g., high-grade NBR/PU polymers, steel sheets). Polymers are compounded with additives for specific properties (hardness, elasticity, chemical resistance). Steel sheets are prepared for stamping.
2. 2. Metal Stamping/Forming: Precision stamping and forming of the steel casing components from selected metal sheets. This often involves progressive die stamping to achieve the intricate DKB profile.
3. 3. Surface Treatment (Casing): The metal casing undergoes cleaning, degreasing, and application of an adhesive bonding agent to ensure a robust bond with the elastomer. This is critical for preventing separation during operation.
4. 4. Rubber Molding/Vulcanization: The prepared elastomer compound is precisely molded and vulcanized (cured) under high pressure and temperature. This process creates the double-lip sealing element, permanently bonding it to the metal casing. Compression molding or injection molding techniques are commonly employed.
5. 5. Precision Trimming & Finishing: Excess flash from the molding process is removed with high precision. Automated trimming machines ensure clean edges and accurate dimensions for the sealing lips.
6. 6. Quality Control & Testing: Each batch undergoes rigorous testing to comply with international standards such as ISO 6195 for reciprocating seals and ANSI B93.36 for fluid power cylinder bore and rod seal dimensions. Tests include dimensional accuracy, material hardness (Shore A), tensile strength, elongation, compression set, and functional tests for sealing performance under simulated operating conditions (e.g., pressure, temperature cycling).
7. 7. Final Inspection & Packaging: Visual inspection for defects, followed by protective packaging to prevent damage during transit and storage.
