SPG SBT-M Motor-Mount Spiral Bevel Gearboxes (MT/ML/MH, 1:1)

SPG SBT-M Motor-Mount Spiral Bevel Gearboxes (MT/ML/MH, 1:1)

SPG SBT-M spiral bevel gearboxes add a motor-mount input flange so a servo or stepping motor can be attached directly, giving a 1:1 right-angle drive. Available with two output shafts (MT), one output shaft (ML) or hollow output (MH).

Key features

  • Direct motor-mount input flange for servo and stepping motors
  • Spiral bevel gears, ratio 1:1, efficiency ≥ 95%
  • MT (2-output), ML (1-output) and MH (hollow output) types
  • Output shaft plain (S) or keyed (K); hollow output on MH
  • Compact, lightweight, high-rigidity housing
  • □25 and □30 motor flanges are special order
