Material: Housing made of steel, black, powder-coated. Tensioning pulley made of ultra-high molecular weight polyethylene based on PE-UHMW, electrostatically dissipative. These very low, ready-to-install belt tensioners enable noise reduction and wear reduction at belts. • With two springs of different strengths that can be activated individually or together. This allows three clamping forces to be set. • Usable tensioning way 40mm. • Max. permissible belt speed 6m/s. Temperature range: -20°C bis +60°C. * Tensioning way. ** Max. recommended belt width. *** Tensioning force range. Adjustable Tensioning Forces: The SPANN-BOY® TS has two different springs: one with low force and one with high force. These springs gan get activated separately or together. So it is possible to adjust three different tensioning forces: Only the low-force spring activated: 65 - 33 N. Only the high-force spring activated: 125 - 63 N. Both springs together activated: 190 - 96 N.
