Caution

Product Description

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

Polyurethane Round Belts, Welded Joint

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
