Conti Synchroflex Timing Belts – Precise PU timing belts manufactured by Conti

Conti Synchroflex timing belts are specially engineered, positive-drive, endless polyurethane (PU) timing belts designed to enable synchronous power transmission without slip. Unlike friction-driven systems, motion is transmitted precisely and consistently, even at high speeds, under dynamic load changes, or within demanding machine cycles. These characteristics make timing belts particularly suitable for high-precision positioning tasks, automated systems, robotics, as well as packaging and conveying technology.

Thanks to their positive engagement, Synchroflex timing belts offer high angular accuracy, low wear, and a consistently high level of efficiency, significantly reducing maintenance requirements. The combination of polyurethane material and steel cord tension members ensures a long service life with consistently stable performance.

The outstanding performance of Conti Synchroflex timing belts is based on the interaction of high-quality materials and a precise manufacturing process:

• High-Performance Polyurethane (PU): The polyurethane used is highly abrasion resistant, temperature-resistant (-30 °C bis +80 °C), and resistant to oils, greases, and many chemicals. At the same time, its elasticity ensures smooth power transmission, reduces noise, and minimizes wear.
• High-Strength Steel Cord Tension Members: The integrated tension members provide excellent dimensional stability and high longitudinal rigidity. They prevent elongation, enable uniform load distribution, and ensure consistently precise positioning with minimal maintenance requirements.
• Precision Displacement Casting Process: The use of displacement casting results in an exceptionally precise tooth geometry. The outcome is smooth running, reduced vibrations, and consistently high motion accuracy, even in demanding positioning applications.
• Endless Manufactured Construction: Synchroflex timing belts are manufactured as truly endless belts. The tension member is embedded helically into the polyurethane, ensuring uniform force transmission without weak points. Unlike welded timing belts, they feature a continuous structure that guarantees high dimensional accuracy and load capacity.

Conti Synchroflex timing belts combine several key advantages that clearly distinguish them from standard solutions:

• Mechanical Precision: Positive-drive timing belt with high angular accuracy and reduced bearing loads
• Low maintenance and long service life: Minimal maintenance requirements, constant length, and efficiency levels of up to 98%
• Low-Noise Operation: Quiet running characteristics due to optimized PU material
• Flexible and Durable: High flexibility combined with excellent load-carrying capacity
• Resistance: Resistant to chemicals, oils, and temperatures fluctuating between -30 °C bis +80 °C

Thanks to these properties, Synchroflex timing belts are also suitable for demanding environments such as cleanrooms, the food industry, or medical applications, without any loss of performance.

The Synchroflex range offers various tooth profiles specifically designed to meet different mechanical requirements:

• T Profile (Standard Profile): Classic trapezoidal profile for general drive applications with moderate loads and versatile use cases
• AT Profile (High-Performance Profile): Further developed profile with increased tooth volume and reinforced tension members for higher force transmission and improved performance
• ATP Profile (Optimised High-Performance Profile): Two-part tooth design with an enlarged contact area for optimised load distribution and reduced mechanical stress during meshing

In addition, a wide range of special profiles is available, including K profile timing belts for precision engineering with small pitches, double-sided timing belts for multi-shaft drives, coated variants for specific friction characteristics, timing belts with cleats for conveying applications, as well as antistatic and custom-engineered solutions. Tailor-made timing belts are also available to meet specific application requirements.

Conti Synchroflex timing belts are used across a wide range of industries, wherever motion must be synchronised, forced must be transmitted efficiently, and products must be positioned with high repeatability.

Mechanical Engineering and Industrial Drive Technology

In machine tools, printing machines, woodworking equipment, as well as pumps and compressors, timing belts are used for the synchronous transmission of rotational motion between shafts. They enable stable process operation even at high speeds and under fluctuating loads, while contributing to reduced maintenance requirements and minimised downtime.

Automation and Robotics

In highly dynamic applications such as pick-and-place systems, linear axes, and handling equipment, timing belts ensure precise motion sequences and repeatable positioning. They are particularly used in axis systems where repeatability and reliable motion control are critical.

Conveying and Material Handling Technology

In conveyor systems, packaging lines, and intralogistics solutions, timing belts serve both as drive elements and transport components. In combination with cleats or surface coatings, they enable the targeted movement, positioning, and separation of products, for example in food processing or internal material flow systems.

Packaging and Food Industry

Timing belts are used in filling, sorting, and packaging systems where a consistent and controlled product flow is essential. Special belt designs allow operators in hygiene-sensitive environments as well as in applications with stringent requirements regarding cleanability and resistance to external influences.

Medical Technology and Cleanroom Applications

In precision-critical applications such as analytical equipment, dosing systems, and cleanroom environments, timing belts in medical technology ensure clean, reliable, and low-vibration motion. In these settings, consistent motion sequences and high process stability are particularly essential.
