Rubber Circular Slitter Blades

 

 

 

 

 

Rubber Circular Slitter Blades are designed for rotary slitting applications where consistency, edge quality, and cutting stability are critical. These blades operate in rotating systems and support continuous cutting of rubber rolls, sheets, and strips.

 

At SHJ KNIFE, we manufacture circular slitter blades for rubber processing with a focus on precision, durability, and OEM compatibility. Our blades perform reliably in high-speed slitting lines and maintain clean cuts across long production runs.

 

 

 

 

 

 

 

 

Material selection depends on cutting speed, rubber type, and production requirements. SHJ KNIFE provides multiple material solutions for rotary slitting applications.

 

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 compounds, cutting speeds, and machine conditions may require tailored material solutions. If you do not see your required material listed or need guidance, our engineering team can recommend the most suitable option for your application.

 

 

 

SHJ KNIFE specializes in OEM rubber circular slitter blades. We manufacture blades based on your exact production needs. Customization options include:

 

 

 

1. What are rubber circular slitter blades?

 

Rubber circular slitter blades are round cutting blades used in rotary slitting systems. They cut rubber rolls, rubber sheets, and continuous rubber strips into narrower widths with stable edge quality and consistent accuracy.

 

2. What are rubber circular slitter blades used for?

 

Rubber circular slitter blades are used for rotary slitting, rewinding, strip cutting, and continuous rubber converting. They are common in rubber sheet processing, conveyor belt production, sealing material cutting, and other industrial rubber applications.

 

3. What is the difference between circular slitter blades and straight slitter blades for rubber?

 

Circular slitter blades rotate during cutting and work best in continuous slitting lines. Straight slitter blades move in a linear direction and are better for guillotine cutting, sheet cutting, and thicker rubber sections. The right blade depends on the machine design and cutting method.

 

4. What is the best material for rubber circular slitter blades?

 

The best material depends on the rubber type, cutting speed, and required blade life. SKD-11 works well for general industrial slitting. SKH-51 and M2 are good for higher-speed applications. Tungsten steel and carbide-tipped blades are better for abrasive materials and longer service life.

 

5. Can rubber circular slitter blades be customized?

 

Yes. Rubber circular slitter blades can be customized by outer diameter, inner bore, thickness, edge geometry, material grade, and tolerance. SHJ KNIFE provides OEM and custom manufacturing based on drawings, samples, or machine specifications.

 

6. How do I choose the right rubber circular slitter blade?

 

You should check the rubber compound, blade size, cutting speed, machine type, and edge quality target. Rotary slitting lines usually require precise blade dimensions and the right material balance between wear resistance and toughness. A custom recommendation is often the best choice for industrial applications.

 

7. Are rubber circular slitter blades suitable for high-speed slitting?

 

Yes. Rubber circular slitter blades are widely used in high-speed rotary slitting lines. For high-speed operation, blade material, grinding accuracy, and dimensional consistency all matter. Proper blade selection helps maintain clean cuts and reduces downtime.

 

8. What industries use rubber circular slitter blades?

 

These blades are used in tire and rubber manufacturing, rubber roll converting, conveyor belt processing, gasket and sealing material production, industrial sheet cutting, and other rubber slitting operations.

 

9. How long do rubber circular slitter blades last?

 

Blade life depends on the material, rubber type, machine condition, cutting speed, and maintenance routine. SKD-11 and D2 are common for standard use. SKH-51, M2, and carbide solutions usually provide longer life in demanding applications.

 

10. Can you make replacement circular slitter blades from samples or drawings?

 

Yes. SHJ KNIFE can manufacture replacement rubber circular slitter blades from samples, technical drawings, or machine details. We can also adjust the material or edge design if you want better cutting performance or longer blade life.
