Rubber Slitter Blades
Rubber Slitter Blades | Circular & Straight Slitting Blades for Rubber
Rubber slitting does not rely on one blade design. Different rubber materials, machine structures, cutting speeds, and edge requirements call for different slitter blade types. At SHJ KNIFE, we supply Rubber Slitter Blades for industrial rubber converting and processing, with a focus on two core solutions: rubber circular slitter blades and rubber straight slitter blades.
This product page helps you choose the right blade style for your process. If your line uses rotary slitting for continuous cutting, circular blades usually offer the best fit. If your process uses straight-line or guillotine cutting for sheets, strips, or thicker rubber sections, straight blades are often the better choice. Both blade types are available with full OEM and custom manufacturing support.
Two Core Blade Types for Rubber Slitting
Rubber slitting systems vary from one factory to another. Some lines run at high speed and require rotary cutting. Others use intermittent cutting, sheet cutting, or heavy-duty straight cuts. For that reason, SHJ KNIFE organizes this category into two practical blade groups.
Rubber Circular Slitter Blades
Rubber Circular Slitter Blades are designed for rotary slitting, rewinding, and continuous web cutting. They are widely used when rubber materials move through the machine in roll form and require stable, repeatable cuts at controlled speeds.
These blades are often selected for:
continuous rubber web slitting
roll-to-roll converting
rewinding lines
narrow strip cutting
production lines that require smooth rotary cutting
Circular slitter blades are a strong option when your machine depends on rotation, speed consistency, and clean edge control.
Rubber Straight Slitter Blades
Rubber Straight Slitter Blades are used for straight-line cutting, guillotine cutting, and sheet rubber processing. They fit applications where the machine uses linear blade motion instead of rotary motion, or where the cutting task involves thicker material sections and batch cutting.
These blades are often selected for:
rubber sheet cutting
strip cutting
guillotine cutting
intermittent cutting processes
cutting thicker or more rigid rubber materials
Straight slitter blades are a practical solution when the cutting method requires direct downward force, strong edge support, and stable straight cuts.
How to Choose the Right Rubber Slitter Blade
The right blade depends on how your machine cuts and how your rubber behaves during processing. In most cases, the first question is not blade material. It is cutting method.
Choose rubber circular slitter blades when your process involves rotary slitting, continuous feed, or roll-based converting. These blades support high-speed slitting and help maintain cutting consistency across long runs.
Choose rubber straight slitter blades when your process involves straight cuts, sheet cutting, guillotine action, or heavier rubber sections. These blades work well in equipment that needs direct cutting pressure instead of rotating motion.
If your production includes multiple rubber products or machine setups, SHJ KNIFE can help evaluate your application and recommend the most suitable blade structure.
Built for Different Rubber Processing Needs
Rubber materials do not all cut the same way. Soft compounds, reinforced sheets, dense rubber strips, and continuous rolls can create very different cutting conditions. A blade that performs well in one slitting line may not work well in another.
That is why we do not treat Rubber Slitter Blades as a one-size-fits-all product. We focus on matching blade type, edge design, dimensions, and material selection to the actual application.
Our slitter blade solutions can support:
- tire and rubber product manufacturing
- industrial rubber converting
- rubber roll slitting
- sheet rubber cutting
- strip cutting lines
- custom machine systems for rubber processing
OEM and Custom Rubber Slitter Blade Service
SHJ KNIFE provides OEM and custom manufacturing for both circular and straight rubber slitter blades. We work with customers who need replacement blades, upgraded blade designs, or blades built around new machine requirements.
We support customization based on:
- Blade type
- Outside diameter or overall length
- Thickness
- Bore size or mounting details
- Edge geometry
- Material grade
- Tolerance requirements
- Machine model or production line setup
You can send us a drawing, sample blade, or machine information. Our team will review the cutting application and produce blades that match your process requirements.
Material Options for Rubber Slitter Blades
Material choice affects blade life, cutting stability, and maintenance cycles. Depending on the rubber grade, cutting speed, and production demands, SHJ KNIFE can supply slitter blades in different steel grades and custom material solutions.
| Material | Hardness (HRC) | Wear Resistance | Toughness | Heat Resistance |
|---|---|---|---|---|
| 9CrSi | 58-60 | ⭐⭐ | ⭐⭐⭐ | ⭐⭐ |
| SKD-11 (Cr12MoV) | 58-62 | ⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐ |
| D2 Tool Steel | 58-60 | ⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐ |
| SKH-51 (W6Mo5Cr4V2) | 62-64 | ⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐ |
| M2 High Speed Steel | 62-64 | ⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐ |
| Tungsten Steel | 65-67 | ⭐⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐ |
| Tungsten Carbide Tips | 90-94 HRA | ⭐⭐⭐⭐⭐ | ⭐ | ⭐⭐⭐⭐ |
In addition to the materials listed above, we offer a wider range of blade material options and customized compositions based on specific industrial requirements. Different rubber types, cutting methods, and machine conditions may require tailored material solutions beyond standard grades. If you are unsure which material best fits your application, or if you do not see your required material listed, our engineering team is ready to assist. Contact us with your specifications, and we will recommend or develop the most suitable blade solution for your production needs.
