MRB/MRL series

The compact and rigid right angle design ensures the highest performance while being space and weight efficient. Ground spiral bevel gear set provides the highest efficiency and lower meshing noise with long service life. Available with solid or hollow shafts on the output end. For output with a hollow shaft, the shaft is extended so a shrink disc can be fitted. Lubricated for life, the gear reducers are virtually maintenance-free (When used under normal conditions).
Three frame sizes are available with gear ratios 1:1, 1:2, 1:3, 1:4 and 1:5

  • Three frame sizes : 42, 60, 90
  • MRB Gear Ratio: 1:1
  • MRL Gear Ratios: 2:1, 3:1, 4:1, 5:1
