Part numbers of metric timing belts are comprised of pitch, pitch length and width. For example; part number T10-630-25 denotes a 630mm pitch length, 10mm pitch and 25mm width.
FEATURES/ADVANTAGES:
- Fiberglass tensile cord provides high strength, excellent flex life, and high resistance to elongation.
- Neoprene body provides protection against grime, grease, oil, and moisture.
- Nylon tooth facing provides a durable wear surface for long service life.
- Eliminates lubrication and re-tensioning to reduce maintenance and labor required on drives.
