| Belt Width: | Belt width refers to the overall width of the belt. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Belt Length: | Belt length (or pitch length), combined with pitch selection, determine the number of teeth. Length may be specified by entering pitch and either number of teeth or pitch length. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Number of Teeth: | Number of teeth, combined with pitch selection, determine the belt length or pitch length. Length may be specified by entering pitch and either number of teeth or pitch length. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Ultimate Tensile Strength: | Breaking strength or tension rating. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Maximum Operating Speed: | Many belts are rated for a maximum operating speed. This is dependent on material and belt geometry. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

| Belt Material | Belt material selection factors may include operating tension, environmental factors such as humidity and temperature, and power transmission. Consult belt manufacturer to optimize material selection. | ||
| Your choices are... | |||
| Neoprene | Neoprene is a synthetic rubber that resists degradation from sun, ozone, and weather. It performs well in contact with oils and many chemicals. Neoprene remains useful over a wide temperature range, displays outstanding physical toughness, and resists burning inherently better than exclusively hydrocarbon rubbers. Neoprene also offers resistance to damage caused by flexing and twisting. Suggested operating temperature (-45° to 230° F). Neoprene was originally engineered by DuPont Dow. | ||
| Polyurethane | Polyurethane is a diverse class of materials exhibiting good elongation, recovery, and toughness properties. They are flexible and have good abrasion resistance. (NOTE: The urethanes of the plastics industry are so named because the repeating units of their structures resemble the chemical urethane.) Trade names include Texin® (Bayer), Adiprene® and Vibrathane® (Uniroyal Chemical), Estane® (B F Goodrich), Genthane® (General Tire and Rubber), Millathane®, and Pellethane® (Dow Chemical). "Polyurethane" and "Urethane" refer to the same material. | ||
| Rubber | Natural compounds such as gum rubber (polyisoprene) and latex. | ||
| Urethane | Urethane (Polyurethane) is a diverse class of materials exhibiting good elongation, recovery and toughness properties. They are flexible and have good abrasion resistance. (NOTE: The urethanes of the plastics industry are so named because the repeating units of their structures resemble the chemical urethane.) Trade names include Texin® (Bayer), Adiprene® and Vibrathane® (Uniroyal Chemical), Estane® (B F Goodrich), Genthane® (General Tire and Rubber), Millathane®, and Pellethane® (Dow Chemical). "Urethane" and "Polyurethane" refer to the same material. | ||
| Other Belt Material | Other, unlisted primary belt material. | ||

| |||
| Reinforced Belt? | Many timing belts are reinforced with fibers or cables in the tension area of the belt. Reinforcement can significantly enhance the maximum operating tension of a belt. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Reinforcement Material: | Metallic and non-metallic reinforcement fibers are available. Consult manufacturer on a specific application for best selection of reinforcement material. | ||
| Your choices are... | |||
| Fiberglass | Fiberglass is strong, durable, and impervious to many caustics and extreme temperatures; fiberglass fabrics are widely used in industry. | ||
| Kevlar® | Kevlar® is a man-made organic fiber developed by DuPont. It is characterized by aramid fibers in an epoxy matrix. The general features of Kevlar are high tensile strength at low weight, structural rigidity and durability, high chemical resistance, low electrical conductivity, and high flame and cutting resistance. It is used in many safety and heavy-duty industrial applications. | ||
| Polyester | Polyethylene terephthalate, also called polyester fiber, refers to any one of a large family of synthetic polymers composed of at least 85% (by weight) an ester of a substituted aromatic carboxylic acid. General characteristics of this family include high tensile strength; chemical, wrinkle, and abrasion resistance; and ease of drying and washability. Industrial uses include belting, hoses, cords and threads; essentially any application where the fiber must be highly flexible, yet durable. Teflon® is a registered trademark of DuPont Dow Elastomers | ||
| Steel | Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content. | ||
| Other | Other, unlisted reinforcement material. | ||
