The line laser is a measuring device for aligning drive pulleys laterally, horizontally and vertically using a laser beam, preventing heavy wear to the edges of the belt. Laser beam range approx. 5 to 10 m Laser class 2 (EN 6082511997) Wavelength 630–680 mm Power < 1 mW Power supply 2 x 1.5 V (LR44) Note Never look directly into the laser beam and do not point it at other people, animals or strongly reflective surfaces. The device and the target points contain highpowered magnets. Individuals with pacemakers should not use the device due to safety reasons. Keep a safe distance away from electronic devices and wristwatches in order to prevent interference. The device must not be used in potentially explosive areas.

Milled toothing, straight teeth. Engagement angle 20°, bright. Note Up to 48 teeth with hub one side, from 50 teeth supplied as disc form. The spur gears have a centre bore or pilot hole (this can vary due to manufacturing methods). For this reason, the dimension D2 max. given in the table is the maximum diameter of the bore with which the spur gears are supplied. This pilot/centre bore can be amended by the customer to produce a reamed bore, reamed bore with keyway or a tapped hole. Alternatively, customers can also use bushes to reduce the bore diameter.

Injection moulded, straight teeth. Engagement angle 20°. Machined bore. Polyacetal, white. Polyketone, ivorytone. Note Polyacetal Standard material with high hardness grade and low coefficient of friction. Polyketone Material with significantly longer service life, higher power transmission and greater security against tooth breakage due to the extraordinarily high wear resistance and very good tribological properties. Can be used under water and other media. Injection moulded gear wheels may have internal manufacturerelated cavities. These may become visible during drilling or broaching. They do not impair the function. The torques specified in the tables relate exclusively to the toothing.

Milled toothing, straight teeth. Engagement angle 20°, bright. Note The gear racks are suitable for mounting in series.

Injection moulded, straight teeth. Engagement angle 20°. Polyacetal, white. Polyketone, ivory tone. Note Polyacetal Standard material with high hardness grade and low coefficient of friction. Polyketone Material with significantly longer service life, higher power transmission and greater security against tooth breakage due to the extraordinarily high wear resistance and very good tribological properties. Can be used under water and other media. Due to the material properties, plastic gear racks are not straightened. L= nominal length 250 mm. The actual length is roughly a whole multiple of the pitch.

Milled toothing, straight teeth engagement angle 20°, bright. Outside diameter extruded, tolerance h9. Note The gear rack teeth are cut using a hob mill. This results in minus tolerances for dimensions H and H1 up to module 2 0.2 mm. module 2.5 to 3 0.3 mm.

Milled toothing, straight teeth. Engagement angle 20°, bright. Axis angle = 90°. Note for ordering Bevel gears are supplied singly. To obtain a pair of bevel gears, please order the specified mating gear as well.

Injection moulded, straight teeth. Engagement angle 20°. Axis angle = 90°. Machined bores from module 1.5. Polyacetal, white. Polyketone, ivory tone. Note Polyacetal Standard material with high hardness grade and low coefficient of friction. Polyketone Material with significantly longer service life, higher power transmission and greater security against tooth breakage due to the extraordinarily high wear resistance and very good tribological properties. Can be used under water and other media. Injection moulded gear wheels may have internal manufacturerelated cavities. These may become visible during drilling or broaching. They do not impair the function. Bevel gear wheels are supplied as single components. To obtain a pair of bevel gear wheels, please order the specified mating gear as well.

Worm screw steel. Worm wheel CuZn37Mn3Al2PbSiS40. Version Worm screw with righthand pitch, casehardened HV 620 – 700, flanks and hole ground. Note for ordering Wheels/screws can only be combined to form a worm gear if they have the same centre distance and transmission ratio. Note A worm gear consists of a worm screw (shaft) and a worm wheel. Suitable for forming worm drives with a 90° shaft angle. A worm drive enables very large speed reduction ratios with a single stage. The toothing has the flank shape K. The engagement angle is 15°. The worm gears are prebored. The stated T2 output torques are the permissible output torques on the worm wheel. These apply for an input speed of 2800 rpm of the worm screw. The worm gears are suitable for continuous operation at high speeds and high torques. Attention 22500171002 Screw polished only. 22500172002 Worm wheel with helical gear toothing.
