SKF washers mainly include spherical washers and sealing washers, which have a variety of characteristics and application scenarios.
Spherical washers
SKF spherical washers are designed to create a precise parallel plane between the bolt head and the nut, automatically adjust to compensate for angular errors, prevent bolt bending, evenly distribute surface pressure, increase clamping length, and thus improve the durability of the bolt. This design is made of high-strength alloy steel, which ensures reliability and durability, reduces bolt fatigue and point contact wear. Sealing washers SKF’s sealing washers adopt a Z-type design to form an efficient labyrinth seal suitable for a variety of application scenarios. They provide a cost-effective solution and are particularly recommended for simple bearing arrangements subjected to harsh working conditions. There are two types of sealing washers: standard design and fluff design, the latter is suitable for difficult working conditions. Depending on the degree of contamination and lubrication interval requirements, multiple sets of sealing washers can be installed and can be combined with other standard seals. In addition, to facilitate lubrication, ZW spacing washers can be installed on both sides of the sealing washers to ensure the free flow of grease.
SKF Washers are precision-engineered components designed to distribute loads, prevent fastener loosening, and protect surfaces in mechanical assemblies. As critical elements in bolted joints and bearing arrangements, these washers ensure secure fastening, reduce friction, and enhance the longevity of machinery. Manufactured with advanced materials and stringent quality controls, SKF Washers deliver unmatched reliability in high-stress applications across industries such as automotive, aerospace, energy, and heavy machinery. Their versatility and durability make them indispensable for maintaining structural integrity and operational efficiency.
Types of SKF Washers
Standard (Type A): General-purpose load distribution.
Hardened (Type H): For high-pressure applications (e.g., flange joints).
Spring Washers (DIN 128): Axial spring action to maintain preload.
Serrated Washers (DIN 6798): Bite into surfaces for anti-rotation.
Bearing Washers: Low-friction surfaces for axial load support in plain bearings.
Composite Thrust Plates: Steel-backed PTFE for self-lubricating applications.
Shoulder Washers: Insulate electrical components in automotive/electronics.
Wave Washers: Compensate for thermal expansion in assemblies.
