General data 8. 10 ContiTech V-belts are based on decades of experience in production and practical application. Any new knowledge gained in the sphere of Power transmission 12 technology is evaluated through constant research and development work and is then applied to production, materials selection and quality assurance.

8 14. 16 Construction ContiTech V-belts are made from high-grade materials, the most suitable material 18 for the specific application being selected for elastomer compounds, tension members and fabric jackets. They are produced on purpose-built equipment, 20 using optimum conditions to produce quality products. 22 The high standard is ensured by constant quality control procedures in alI stages of production 24. Properties 26. ContiTech V-belts have been purpose-designed for their specific requirements. 28 They meet the demands of modern technology for maximum operating reliability and economic efficiency. 30. Matched sets 32 In a single high precision process and using state of the art technology, matched sets of V-belts are manufactured in exactly the same length.

9 On multi-belt drives 34 their even load distribution ensures high Power transmission capacity and their long service life ensures good cost-effectiveness. They are low-stretch, smooth 36 running, and the tension stays constant. With these properties there are no restrictions on putting together sets of 38 matched-length belts. Ordering and warehousing procedures are simplified as all V-belts can be used for single-belt or multi-belt drives. Belts do not have to be 40 ordered in bundles. 42 CONTI FO -Z, CONTI ULTRAFLEX and CONTI MULTIFLEX are supplied in bulk for lengths from 1000 mm. The standard lengths allow immediate availability and 44 hence economic inventory levels at the user.

10 In the event of a failure of a single V-belt on a multi groove drive, all belts are to 46 be replaced by matched-length belts. 48. 50. 52. 54. 56. 58. 60. 62. 64. 66. 68. 70. 72 6. 74. 2. Product identification 1. 4. 6. Standard properties All ContiTech V-belts have certain properties as standard features: 8. Moderate resistance to oil 10. Oil or grease acting on the belt briefly and only occasionally has no effect on efficiency and service life. Tests at up to 70 C on V-belts that have been exposed 12. completely to ASTM oils have shown that they have a high resistance to hydrocarbon oils. 14. The wide range of oils and especially of additives available on the market pre- vents any general claim being made with respect to oil resistance.
