Frame brass. Tubular bubble vial glass. Version Nickelplated and highgloss polished. Form B black anodised. Note Bubble levels are used as a type of zero indicator instrument for checking horizontal inclination in e.g. spirit levels, inclinometers, metrology instruments and machine constructions. The tubular levels can be fastened using the two holes. Form A one sight window Form B three sight windows Sensitivity in angular minutes for 2 mm bubble travel Green filling

Packaging unit 5 metres with odd number of links. Ending with an inner link at both ends. Connecting links must be ordered separately. Note Europeantype roller chains acc. to DIN ISO 606 with curved link plates (ISO No. 06 with straight links). All chains are prestretched. Initial lubrication anticorrosion mineral based oil. B7 = maximum value for links. Pitch = PxB1

Connecting links for DIN ISO 606 duplex roller chains. By Form E, the spring clip must be mounted with the closed end facing the direction of movement. Offset links are required to close the chain if there is an odd number of links. Using offset links reduces the power and tensile strength by 20%.

Packaging unit 5 metres with odd number of links. Ending with an inner link at both ends. Connecting links must be ordered separately. Note Europeantype DIN ISO 606 roller chains with curved link plates (ISO No. 06 with straight links). All chains are prestretched. Not lubricated, the chains must be lubricated depending on the application. The stainless steel roller chains offer excellent corrosion protection and good chemical resistance. They can be used in applications with water and at high temperatures. B7 = maximum value for links. Pitch = PxB1

Ready to install sprockets with hub on one side for DIN ISO 606 roller chains. Teeth are milled and inductively hardened. Keyway acc. to DIN 6885 / BS 4235. The keyway is aligned with the tooth tip. With two grub screws. One tapped hole aligned with the keyway centre, the other offset by 90°.

Steel C45. Grey cast iron GG22 from 38 teeth. Sprockets with hub one side for DIN ISO 606 roller chains. The sprockets have a centre bore or are predrilled (this can vary due to production methods). For this reason, the dimension D3 max. given in the table is the maximum diameter of the bore that the sprockets are supplied with. This pilot hole/centre bore can be customised with a reamed hole, reamed hole with keyway or a tapped hole by the customer. Alternatively, bushes can be fitted by the customer to reduce the diameter.

Sprocket steel. Ball bearing chrome steel. Screw and nut steel. Version Sprocket teeth hardened to HRC 50, electro zincplated. Ball bearing with sealing discs 2ZC3. Screw ISO 4017, grade 8.8, electro zincplated. Nut ISO 4035, grade 8, electro zincplated. Note For tensioning roller chains. The sprocket set can be combined with all tensioning elements to form a readytoinstall chain clamp. The ball bearings are sealed both sides, permanently lubricated and maintenancefree. The sprocket can be moved on the screw and thus adapted to the chain track. With the duplex and triplex version, precision spacer sleeves ensure correct chain guidance. Rigid mounting without a tensioning element is also possible. Can also be used as an idler sprocket.

Tensioner Vesconite® plastic. Screw and nut steel. Version Screw ISO 4017, grade 8.8, electro zincplated. Nut ISO 4035, grade 8, electro zincplated. Note For tensioning roller chains. The chain tensioner set can be combined with all tensioning elements to form a readytoinstall chain clamp. The symmetrical design enables use on both sides. Large radii ensure very quiet running. The highquality plastic does not require any lubrication. The maximum chain speed should not exceed 1.5 m/s in continuous use.
