POLYFLEX OPTIBELT

Optibelt WR is a cast polyurethane V-belt with a top width from 3 mm to 11 mm, suitable for extremely small diameter pulleys. Often used in compact, high-speed drives such as machine tools, milling machines, small woodworking machines, metalworking. Resistant to oils, chemicals and ozone.

Advantages of Polyflex belts

Compact design
They are ideal for small pulleys and tight spaces, making them perfect for precision machinery such as lathes, milling machines and spindle drives.

High power transmission at high speeds
Thanks to their 60° angle design and polyurethane material with HMPE (high modulus polyethylene), they can transmit high forces even at over 10,000 rpm.

Long service life and low maintenance cost
They require less post-tensioning and are highly resistant to heat, chemicals and oil, which reduces the need for maintenance and increases operational reliability.

Even load distribution and stability
Ribbed back and the specific angle provide better lateral stability and reduce bending stresses, which is important in applications with many start/stop cycles.

Quiet and vibration-free operation
The flexible design contributes to smooth and quiet operation, which is especially valuable in sensitive environments or where noise levels are a factor.
