The S8MK13 Polyurethane Timing Belt is based on the S8M curvilinear tooth profile (8 mm pitch) and features an integrated K13 polyurethane guide molded directly on the belt back.
Structurally, it combines:
The high torque transmission capability of S8M belts
The strong lateral guidance of K13 profile
This configuration ensures stable tracking, improved alignment, and reliable performance in medium to heavy-duty guided conveying systems.
The guide is molded as part of the belt body, eliminating detachment risks associated with glued or welded guides.
