Washer 40xØ19x1.5mm

The 40x19x1.5 mm washer is a mounting component used in pressure washer assemblies where proper load distribution, part positioning, or protection of contact surfaces is required. The galvanized metal version is used in service and assembly work, including areas related to the wheel in the Therm series.

MPN / reference: 46533
Dimensions: 40 x Ø19 x 1.5 mm
Material: galvanized metal

APPLICATION

The washer is used in typical service and assembly work:

• distribution of load in bolted or axial connections,
• setting the correct spacing and position of components,
• protecting contact surfaces against point loading,
• replacement of a worn or corroded mounting element,
• service work including around the wheel in Therm series units.

SYMPTOMS - WHEN IT IS WORTH REPLACING

It is worth considering replacing the washer when the following appear:

• deformation or wear of the washer surface,
• signs of corrosion weakening the component,
• play in the connection caused by wear of the spacer element,
• mechanical damage after disassembly,
• uneven clamping or signs of improper operation at the mounting point.

HOW TO CHOOSE THE RIGHT PART

Selection of the washer should be done carefully:

• verify the dimensions 40 x Ø19 x 1.5 mm,
• confirm the manufacturer number: MPN 46533,
• compare with the removed part: outer diameter, inner diameter, and thickness,
• check suitability for the specific mounting point.

With mounting components, even a small difference in thickness or diameter may affect correct seating and operation of the entire connection.

COMPATIBILITY

The washer should be selected based on MPN 46533 and the dimensions 40 x Ø19 x 1.5 mm, according to the service documentation or the removed part. The indication that it is used, among others, near the wheel in the Therm series should be treated as an area of application that requires confirmation by part number and dimensions.

[faq]

Can a regular washer of a similar size replace this part?|Not always. In technical connections, exact diameters, thickness, and the way the part works matter. The safest approach is to rely on MPN 46533 and the dimensions from the description.

Why does the 1.5 mm thickness matter?|Thickness affects connection setup, load distribution, and possible spacing between parts. Even a small change can affect the operation of the whole assembly.

Does a galvanized washer have an advantage over a plain steel one?|Galvanization improves surface resistance to corrosion, which matters in a working environment exposed to moisture and contact with water.

How can I tell that the washer is already due for replacement?|Most often by deformation, corrosion, wear marks, or when the connection no longer works stably despite correct installation of the other components.

Does such a washer serve only as a “small mounting accessory”?|No. In many assemblies it is responsible for correct clamping force, spacing, and connection stability, so its selection has a real impact on subassembly operation.
