The powerful optibelt ALPHA POWER timing belts are the result of consistent further development. The company’s wide-ranging experience with its ALPHA TORQUE timing belts has been incorporated in this belt generation.

Made with a new, more resistant and more durable polyurethane compound, the performance of this generation is up to 30 % higher than that of the previous optibelt ALPHA TORQUE.

By enabling a more compact drive design, the optibelt ALPHA POWER helps cut costs, starting with the purchase costs for new belts and pulleys.

The optimised interplay of the polyurethane, with a hardness of 88 Shore A, and the steel cord ensures that the optibelt ALPHA POWER offers an extremely economical solution for a particularly wide range of applications.

The optibelt ALPHA TORQUE is made from abrasion-resistant polyurethane with a hardness of 86 Shore A. Good resistance to oil plus a certain resistance to acids and alkaline solutions are standard features of this polyurethane.

The optibelt ALPHA TORQUE can be reinforced with tension cords made of steel, highly flexible steel, stainless steel, aramid, polyester or Vectran to suite a wide range of applications.

The optibelt ALPHA FLEX timing belt is manufactured to the customer’s length specification as an endless belt without any breaks in the tensile reinforcement. This means that two spirally wound tension cords are used.

These can be made of steel, highly flexible steel or stainless steel to suit a wide range of applications.

In the case of belts that are at least 1,500 mm long, the tooth side of the optibelt ALPHA FLEX can be covered with polyamide fabric (PAZ).

Open-ended optibelt ALPHA LINEAR timing belts are made of extruded, thermoplastic polyurethane with tension cords parallel to the edges. The belts are dimensionally stable and their precise positioning makes them ideal for use in linear drive systems.

It is also possible to apply transparent polyurethane (with a hardness of 85 Shore A), T2, yellow PU foam or other materials directly to the belt in an additional downstream extrusion process.

The optibelt ALPHA LINEAR timing belt can also be given a thin fabric covering on the tooth side in order to reduce friction and noise. Fabric can also be applied to the belt back.

optibelt ALPHA V timing belts are made from open-ended, extruded optibelt ALPHA LINEAR timing belts that are welded together to achieve the specified length. They are used primarily in transport systems.

Despite the break in the tension cords at the finger spliced joint, the welded timing belts still achieve at least 50% of the permissible tractive force achieved by belts with continuous cords. This is due to the high strength of the thermoplastic polyurethane.

When polyamide fabric is welded to the polyurethane belts, the fabric is simply butt jointed and not bonded together at its ends. In contrast, reinforced top surfaces and T2, yellow PU foam and APL plus coatings as well as the tooth side of the belt can be welded together as a joint-free composite.

The ZS / ZSi timing belt joint The timing belt joint ZS / ZSi is designed to allow repeated detaching and joining of timing belts in the plant itself.

Versions are available for the AT10, T10 and H profiles.

Both versions are offered in stainless-steel as standard for the AT10 and H profiles. For the T10 profile, the tooth side inserts are made of brass.

The PINJOIN timing belt joint The PINJOIN timing belt joint is designed for permanently joining belts, one time only, in the plant. Version available for profile AT10.

The connection is made by means of stainless-steel threaded pins that fit into laterally drilled holes running longitudinally through the tooth.



Profile: Diameters from 2 to 20 mm

Optibelt RR round section belts are made from high quality polyurethane using a special manufacturing process. They are produced as open-ended belts in various diameters and are available by the metre.

The optibelt RR Plus version incorporates a polyester tension cord. The round section belts with tension cords are particularly low-stretch are therefore especially useful where longer transport distances need to be covered.



Profile: The ALPHA SRP moulds are based on those of the ALPHA TORQUE and ALPHA POWER timing belts.

The optibelt SRP timing belt with cast cams and coatings is manufactured in a single production step and used in conveying systems.

The polyurethane is cast between the core mould and the special outer mould with correspondingly increased internal diameter or special outer moulds with the desired contour for the cams.

By rotating the inner and outer moulds around the central axis, a shore hardness that differs from that of the teeth can be cast using a centrifugal casting process
