SKF W13 Steel Bearing Lock Washer 2.588″ x 3.578″ x 0.053″ Design

Description

Product Overview

The SKF W13 steel bearing lock washer is engineered to deliver superior performance in demanding industrial environments. Measuring 2.588 inches in outer diameter, 3.578 inches in inner diameter, and a thickness of 0.053 inches, this compact component fits a wide range of standard fastener assemblies. Constructed from high‑grade carbon steel, the washer undergoes a precise heat‑treatment process that enhances hardness and resistance to wear. Its wedge‑type locking design creates a self‑tightening action when the bolt is torqued, effectively preventing loosening caused by vibration, thermal expansion, or dynamic loads. The product complies with rigorous industry standards and is manufactured by RDV Bearings, a trusted supplier known for precision engineering. Its compact profile, combined with a robust material composition, makes it an ideal choice for applications where space is limited but reliability cannot be compromised.

Usage

Designed for a broad spectrum of industrial applications, the SKF W13 lock washer excels in machinery, equipment frames, conveyor systems, and heavy‑duty assemblies. It is particularly effective in environments with high vibration, such as automotive manufacturing lines, agricultural equipment, and mining machinery. The washer’s wedge mechanism ensures that bolts remain securely fastened even under fluctuating loads, reducing maintenance intervals and downtime. Installation is straightforward: simply place the washer between the bolt head and the mating surface, then apply the recommended torque. The washer’s dimensions allow it to be used with standard metric and imperial fasteners, making it a versatile component for engineers, maintenance technicians, and OEMs seeking dependable fastening solutions.

FAQ

What size fasteners are compatible with the SKF W13 lock washer?

The washer is designed for bolts and screws with an outer diameter of 2.588 inches and an inner diameter of 3.578 inches, covering a wide range of standard metric and imperial fasteners.

Can the washer be used in corrosive environments?

Yes. The steel material is heat‑treated and can be further protected with standard corrosion‑resistant coatings, making it suitable for outdoor or chemically aggressive settings.

How does the wedge design prevent loosening?

When the bolt is torqued, the wedge shape creates a radial force that locks the washer in place, resisting rotation caused by vibration or thermal expansion.

Is there a recommended torque specification?

We advise following the torque values provided in the equipment manufacturer’s guidelines. Generally, a torque that achieves a snug fit without over‑tightening will activate the wedge locking action effectively.

What warranty does SKF provide for this product?

SKF offers a standard limited warranty covering material defects and manufacturing errors for a period of one year from the date of purchase, along with full technical support.
