Double-sided rubber timing belt
A double-sided rubber timing belt has teeth on both surfaces. Matching a replacement requires the profile on each side, their relative alignment and the complete belt section, as well as width and pitch length. Include the belt routing and pulley arrangement with your enquiry.

Matching both tooth surfaces
The tooth profiles and their alignment must suit the pulleys on both sides of the belt. Supply a side-view drawing showing tooth height on each face, the central belt section and overall thickness. A single-sided belt thickness does not establish the total thickness of this double-sided construction.
| Detail | Information to provide |
|---|---|
| Belt identification | Complete printed marking, equipment model and part number |
| Dimensions | Width, pitch length or tooth count, both tooth profiles and overall thickness |
| Construction | Alignment of the two tooth rows, cord and fabric requirements, and joint or endless arrangement |
| Working conditions | Speed, load, temperature, bending arrangement and contact with oils or cleaning agents |
Rubber timing-belt profile reference
The following dimensions cover several profile families in the range. Match the complete profile designation to your pulley; a shared pitch alone does not establish interchangeability. These series references do not define a double-sided finished section. In particular, use the product drawing for overall thickness and tooth alignment instead of adopting the single-profile belt thickness below.

Custom processing
If the replacement requires a covering, holes, guides or other processing, show their dimensions and locations on the drawing. Include close-up photographs of the tooth side, back surface and any processed features so we can discuss the required arrangement.
