SKF PHG 225-3M-9 Timing Belt 75 Teeth, 225 mm Length, 9 mm Width

This timing belt is a toothed power transmission belt designed for precise synchronous drive applications in automation, electronics, electrical and mechanical systems. It delivers consistent tooth engagement for motion control and positioning tasks where accurate speed ratios and repeatable timing are required.

• 3mm pitch ensures consistent tooth spacing for accurate indexing
• 75 teeth provide stable engagement for multi-tooth load sharing
• Fibreglass cord offers high tensile strength under tension
• 9mm width allows Compact routing in confined drive layouts
• 225mm pitch length suits short-centre transmission arrangements
• RoHS compliance supports use in regulated installations

• Suitable for CNC positioning stages requiring precise indexing
• Ideal for conveyor drives with Compact centre distances
• Used with stepper motor systems in automation assemblies
• Can be used for timing drives in electrical actuators
• Used for synchronising pulleys in small mechanical equipment

The belt uses fibreglass cords which provide high tensile modulus and reduced stretch compared with common fabric reinforcements, maintaining timing accuracy over extended cycles.

A higher tooth count increases the number of engaged teeth at any instant, reducing bending stress per tooth and improving load sharing across the belt for smoother torque transmission.

The belt’s 3mm pitch matches pulleys designed to that tooth spacing, ensuring correct meshing and preventing skipping or premature wear.

The 225mm pitch length is appropriate for Compact centre distances and short-loop belt paths commonly found in small automation modules and benchtop machinery.
