Double-sided PU timing belt
The product photograph shows a red profiled surface on one side and a light-coloured toothed surface on the other. For a replacement, send photographs of both sides and a cross-section drawing so the working surface, tooth profile and finished thickness can be matched to your assembly.
| Item | Product details |
|---|---|
| Belt type | Double-sided PU timing belt |
| Surface shown | Red profiled side and light-coloured tooth side |
| Tooth profile | Match to your pulley drawing or belt sample |
| Finished size | Specify width, length and overall thickness |
| Surface geometry | Include profile shape, spacing and alignment |
Send the full belt marking, cross-section and operating conditions with your inquiry.
Match both working surfaces
Show the tooth-side dimensions and the opposite surface separately on the drawing. Include any grooves, raised sections or shaped contact areas, together with their position along the belt. For a replacement, also provide the pulley arrangement and the machine part number.
| Detail | Information to provide |
|---|---|
| Belt dimensions | Width, finished length or tooth count, tooth height and overall thickness |
| Surface layout | Cross-section, profile spacing, grooves and the alignment of features on both sides |
| Construction | PU belt specification, required material for the opposite surface, tensile-cord material and joint arrangement |
| Machine conditions | Pulley drawing, speed, load, working temperature and contact with oils or cleaning agents |
Timing belt series reference
The table below covers 22 timing-belt profiles. These series dimensions do not define the complete cross-section of the double-sided belt shown. Specify the geometry of each side and the overall finished thickness on your drawing; use the profile designation and pitch to discuss the pulley match.
