Spliced Timing Belt VS Seamless Timing Belt Comparison

Spliced timing belt and flex timing belt are both belong to endless synchronous belts, their main difference lie in joint part, which cause they have different structure construction, manufacturing technique and applications.

Spliced Timing Belt

Structure and Manufacturing Technique

• Material: Spliced toothed belt is generally made of polyurethane with steel or Kevlar reinforced core.
• Joint: Spliced timing belt is generally connected belt both ends into circle shape by hot melt or mechanical joint.

Features

• Adjustable length: The belt length can be adjusted to any length, which is very flexible.
• Convenient maintenance: When the toothed belt is damaged locally, it can be replaced partially without replacing the whole belt, reducing the maintenance cost.
• Weak point at joint part: The joint part is weak point, the strength and wear resistance is weaker due to the inside steel core is not joint at this position.

Applications

• Suitable for the situation where belt length is customized and curve drive and incline transmission.

Seamless Timing Belt

Structure and Manufacturing Technique

• Material: Seamless toothed belt is generally made of polyurethane and rubber with steel or fiberglass cord.
• Seamless toothed belt is made from mold without any joint.

Features

• Stable operation: There is no bounce during operation.
• Uniform strength: Due to the belt is continous, there is no weak point at joint part so the whole belt has the uniform tensile strength at every point.
• Better wear resistance: Due to the belt is seamless, which avoids wear at joint point and enhances belt service life.

Applications

• Seamless toothed belt is ideal for high accuracy, high speed and high load transmission system.
