Polyflex Belts provide a versatile power transmission solution when space is at a premium. Their unique 60° angle polyurethane construction transmits greater loads at higher speeds in less space than conventional V-belts. This compact and strong belt with nominal top width from 3 mm to 11 mm transmits more power and allows high speed ratios. Polyflex® is suited for extremely small diameter pulleys and very compact drives with high rotational speeds. Ideal for use on machines and machine tools requiring high performance and smooth operation in limited space such as bench type milling machines, lathe drives, woodworking and metalworking machine spindle drives, computer peripheral equipment, small blowers, etc.

  • High Modulus Polyurethane compound (HMPE) resists fatigue, wear, ozone, and most environmental conditions.
  • Precision casting eliminates layers and overlaps to enable low vibration operation.
  • Temperature Range: -54°C up to +85°C (-65°F up to +185°F).
