Tubular bubble levels with frame to screw on

Bullseye level body stainless steel up to Ø14 mm, then aluminium. Sight window glass. Version Aluminium 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. Excellent bubble contour, with internal bubble ring to eliminate planar parallaxes. Sensitivity in angular minutes for 2 mm bubble travel Clear filling

Frame brass. Bullseye level body polyamide. 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. These bullseye levels can either be screwed down using the three holes (Form A) or recessed (Form B). Form A calibrated to the ground bottom face Form B calibrated to the underside of the flange Sensitivity in angular minutes for 2 mm bubble travel Clear filling Black contrast ring White level base

These precision slideways with roller bearings are used in machine and fixture construction, metrology, optical instruments and precision mechanics. The scale division on the micrometer dial is 0.02 mm. The stated permissible load values (F) are designed for a service life of 1 million travel cycles. The torque values apply only to centred slides. An additional centring hole is located at holes D2 and D3 on the top of the slide. Other connecting elements can be precisely mounted on the slide in combination with our centring rings 20240. F = permissible loading for dynamic and static loads. TI E/E1 = number of fastening holes E/E1/M inside. TA E/E1 = number of fastening holes E/E1/M outside. TI E4 = number of fastening holes E4/D1 inside. TA E2 = number of fastening holes E2/D1 outside.

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.
