Description
SKF Z 204 F belongs to sealing washers, part of our Seals range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for Z 204 F and any equivalents.
Sealing washers in the SKF Z F series work as axial seals, fitted either on a shaft or into a housing to hold lubricant in place and keep contaminants out. They are produced from elastomers that stand up to oils and greases, and they suit assemblies where space along the axis is tight.
Reading the code: the Z prefix is followed by a three-digit number that sets the size, and the F at the end marks a specific profile or material. Small diameters fall under references such as Z 005 F, Z 006 F, Z 008 F, Z 009 F and Z 010 F, while Z 201 F, Z 202 F and Z 203 F cover larger ones. Since the digits do not translate straight into a diameter, confirm the size against the drawing or the part you are replacing.
Typical installations include gearboxes, pumps, electric motors, transmission equipment, and agricultural or road machinery. They also appear in mills, conveyor belts and process equipment, where an axial seal stops oil from escaping and blocks dust or water from getting in. A second common role is as a backup seal alongside bearings and bushings.
When choosing a washer, check three things: the shaft or housing diameter, how much width is free, and whether the elastomer is compatible with the lubricant in use. During fitting, the sealing face should point toward the fluid being contained, and the lip must not be twisted or struck. A light pre-lubrication of the lip plus careful alignment helps the seal last.
Interchange with seals from other makers is possible, but only when dimensions and material line up. A similar code is not proof of equivalence; compare diameters, thickness and elastomer type instead. If anything is unclear, send us the exact size and we will point you to a suitable option.

Frequently asked questions
- What does the F in Z F washers indicate?
- It denotes a profile or material variant inside the Z series. Nominal size stays the same, but the elastomer type and its resistance differ. Always check the full part number and dimensions to confirm equivalence.
- How do I pick the right washer size?
- You need the shaft or housing diameter, the available width, and the lubricant type. Use that data to compare the SKF part number or contact us on WhatsApp. The series number by itself is not enough, as it can differ between manufacturers.
- Can SKF washers be swapped with other brands?
- They can be interchangeable when dimensions and material match. No universal equivalence table exists, so verify size by size. At MR we help you compare against the original part or drawing.
