PU timing belt with rubber covering
This PU timing belt has a rubber covering on its outer contact surface. The product photograph shows a green covering and a light-coloured toothed side. For a replacement, specify the base belt profile and the covering separately, including the finished dimensions needed for your machine.
| Item | Product details |
|---|---|
| Product | PU timing belt with rubber covering |
| Belt body | Polyurethane (PU) |
| Tooth profile | Match to your pulley drawing or belt sample |

Send the existing belt marking, covering requirements and operating conditions with your inquiry.
Specify the rubber contact surface
Include the covering thickness and required hardness with the belt drawing. Show whether the contact surface is smooth, patterned or requires additional processing. To discuss the covering for your equipment, describe the item being handled and any contact with oils, cleaning agents or heat.
| Detail | Information to provide |
|---|---|
| Belt dimensions | Width, finished length or tooth count, tooth height and overall thickness |
| Rubber covering | Material requirement, thickness, hardness and smooth or patterned finish |
| Construction | Base belt profile, tensile-cord material, joint arrangement and any guide requirements |
| Machine conditions | Pulley drawing, speed, load, working temperature and contact with oils or cleaning agents |
Profile and pitch reference
The following profile designations and pitches are references for matching your existing belt. A shared pitch does not establish the same tooth shape or finished belt thickness. Use the full profile designation and a cross-section drawing for the required construction.

| H | 12.7 |
| L | 9.525 |
| XL, DXL | 5.08 |
| MXL, DMXL | 2.032 |
| S2M | 2.0 |
| S3M, D3M | 3 |
