maximum temperature range: -40°C up to +350°C
maximum axial shaft misalignment: Δ A = ± 1,5 mm
maximum angular shaft misalignment: α = 1°
maximum lateral shaft misalignment: Δ R = tan α • L x with Lx – (2 • L1)

calculation example: WD-VA 100 / L = 600 lateral shaft misalignment: with Lx = 600 – (2 • 43) = 514 mm; α = 1° > Δ R = tan 1° • 514 mm = 8,9 mm

• clamping hubs with stainless steel screws A4/80 without EASY pin – regard reduced tightening torque!
• check torque transmission of shaft-hub-connection for shaft diameter smaller Dmin kontrollieren! (request possible)
• optional coated screws of strength class 12.9 for higher clamping forces or torque – (see value in brackets).
• variable length up to 6m, and higher rotational speed on request
