Polyurethane Round Belts-Welded Joint/Standard Type/High Tensile Strength Type/Antistatic Type
:
MISUMI
Round belt of rope shape is cut into any specified length and made endless with heat welding.
Polyurethane Round Belts, Welded Joint
Rope-shaped polyurethane round belts cut to the specified length and made endless by heat welding. Available as standard, high tensile strength and antistatic types.
- MBT and MBTH comply with the Japanese Food Sanitation Act.
- MBTD contains carbon antistatic material, effective where static electricity is a concern.
- MBTH: from February 2023 shipments, the surface unevenness has been reduced. This does not affect use.
Dimensional drawing
- The joint may look slightly thicker, but it reaches the proper diameter under running tension.
| Type | Type | Surface pattern | Color | Material | Heat-resistant temperature |
|---|---|---|---|---|---|
| MBT | Standard | Mirror finish | Orange | Polyurethane | 80°C |
| MBTH | High tensile | Rough surface | Green | 80°C | |
| MBTD | Antistatic | Rough surface | Black | 50°C |
- MBTD contains an antistatic material (carbon), useful where static electricity is a problem.

- The recommended elongation for MBT and MBTH is 3% to 4%.
- An initial elongation of about 5% is recommended for MBTD.
- The circumference is the center diameter through the center of the rubber diameter d (the diameter through the P.D. on the pulley side).
Example: for a circular shape, circumference = (I.D. + d) × π
