In textile rotary screen printing, the squeegee is an important component in the paste transfer process. Working inside the rotary screen, it helps push printing paste through the screen openings and onto the moving fabric.
Selecting the correct squeegee is important for maintaining consistent paste application and achieving the required printing results. However, the right choice depends on more than just the blade material. Hardness, dimensions, profile, machine configuration and printing conditions should all be considered.
In this guide, we explain the key factors to check when selecting replacement squeegees for textile rotary screen printing machines.
A squeegee is a blade or scraping component installed inside a rotary screen printing machine. During printing, it applies pressure to the printing paste inside the rotating screen, helping the paste pass through the open mesh areas onto the fabric.
The squeegee works together with several other components, including the rotary nickel screen, end rings, repeat heads and paste supply system.
Its condition and specification can influence paste transfer, print consistency and the appearance of the finished fabric.
For this reason, selecting a suitable replacement squeegee is an important part of rotary screen printing machine maintenance.
Two squeegee options used in textile printing applications are polyurethane (PU) squeegees and stainless steel squeegee blades. They have different material characteristics and should be selected according to the machine design and printing requirements.
Polyurethane squeegees are flexible industrial blades used in compatible rotary screen printing systems.
Depending on the formulation and hardness, PU can offer a combination of elasticity, abrasion resistance and wear resistance.
Potential selection considerations include:
Required blade hardness
Blade profile and dimensions
Flexibility and edge condition
Compatibility with the printing paste
Fit with the existing squeegee holder
PU squeegees are available in different specifications. The correct hardness and profile should be confirmed according to the original equipment and application rather than selected by hardness alone.
For example, our T-Type PU Printing Squeegee is intended for compatible textile rotary printing machines. Please check the product details and confirm the required profile and dimensions before ordering.
Stainless steel squeegee blades provide a more rigid blade structure than flexible PU blades.
Depending on the machine configuration, they may be used where a metal doctor blade or scraper is specified.
When selecting a stainless steel blade, check:
Blade thickness
Blade width
Required length
Straightness and edge condition
Holder compatibility
Compatibility with the printing process and paste
Our Rotary Printing Stainless Steel Squeegee Doctor Blade Strip is available for customers looking for a metal blade solution for compatible printing applications.
Important: PU and stainless steel blades are not automatically interchangeable. Always confirm the original machine configuration, blade holder and required specification before changing materials.
For PU squeegees, hardness is one factor that affects blade deformation and contact with the inside of the rotary screen.
A softer blade generally deforms more readily under pressure, while a harder blade tends to maintain a firmer profile. The resulting paste transfer also depends on blade geometry, screen mesh, paste properties, machine speed and operating pressure.
When choosing hardness, consider the following:
Printing requirements: Fine details and broad areas of coverage may require different combinations of screen, blade and process settings.
Printing paste: Paste viscosity and flow characteristics influence how easily paste passes through the screen openings.
Screen specification: Mesh count and open area affect paste transfer and should be considered together with the squeegee.
Machine requirements: The original blade specification and holder design provide an important starting point for replacement.
There is no single hardness that is best for every textile printing application. When replacing an existing PU squeegee, matching the original specification is generally the safest starting point.
Incorrect dimensions may cause installation difficulties or prevent the blade from working as intended.
Before ordering a replacement squeegee, check the following measurements.
Confirm the required blade length according to the machine and printing width. Do not assume that the fabric width alone determines the blade length.
Check the cross-sectional dimensions of the original blade. These measurements are particularly important when the blade must fit into an existing holder.
Confirm whether the machine requires a T-type PU profile, a flat blade strip or another specific design.
A similar-looking blade may not fit the original holder correctly.
Check the holder slot, clamping method and installation arrangement. If the profile differs from the original component, compatibility should be verified before ordering.
Confirm whether the required replacement is PU, stainless steel or another specified material. For PU blades, record the original hardness if available.
If you are unsure about the specification, photographs and a sample of the existing blade can help with identification.
A worn or damaged squeegee may contribute to inconsistent printing performance. However, similar printing defects can also result from screen condition, paste properties, machine settings or other components.
During routine maintenance, check for the following signs:
A worn, chipped or uneven blade edge
Visible deformation or damage
Uneven blade contact
Inconsistent paste transfer across the printing width
Repeated printing defects after other process factors have been checked
Inspect the blade and its holder regularly, following the machine manufacturer's maintenance procedures.
When a replacement is necessary, verify the blade dimensions, material and profile before installation.
Providing clear technical information helps reduce the risk of selecting an incompatible replacement.
When requesting a quotation for a rotary screen printing squeegee, please provide as many of the following details as possible:
Machine brand and model: Identify the rotary screen printing machine.
Blade material: PU, stainless steel or another specified material.
Blade profile: For example, T-type or flat blade strip.
Dimensions: Length, width and thickness, as applicable.
PU hardness: Provide the original specification if available.
Quantity required: State the quantity and preferred supply format.
Photos or drawings: Include clear images of the original blade and holder where possible.
If you do not have a complete technical drawing, you can send us the original blade dimensions and photos for an initial specification review.

If you are looking for a replacement squeegee for your textile rotary printing machine, please send us the machine model, required dimensions, material specifications or a photo of the existing blade. We can review the information and help you identify a suitable replacement.
A squeegee works inside the rotary screen and helps push printing paste through the open mesh areas onto the fabric. Its specification and condition can affect paste transfer and printing consistency.
A PU squeegee is a flexible polyurethane blade, while a stainless steel squeegee is a more rigid metal blade. Their suitability depends on the machine design, holder configuration and printing requirements. They should not be treated as interchangeable without checking compatibility.
The appropriate hardness depends on the original machine specification, blade profile, screen, printing paste and required printing result. If possible, confirm the hardness of the original blade before ordering a replacement.
Check the blade length, width, thickness, profile and holder dimensions. Providing the machine model, original blade photos or a technical drawing can help verify the required specification.
Yes, you can provide a photo, drawing or physical sample for specification checking. The machine model, blade material, dimensions and holder configuration are useful details to include with your inquiry.
Choosing the right rotary screen printing squeegee requires more than selecting a material. Blade dimensions, profile, hardness, holder compatibility and printing conditions should all be considered.
Whether you need a PU printing squeegee or a stainless steel doctor blade strip, checking the original specification is an important step before ordering.
