Offset output drive VNK2A181, size 4, 15 to 138 Nm, 1/2 in square - Bosch Rexroth 0608800632

For automated tightening in size 4, the offset output drive VNK2A181 brings a 1/2 in square drive to the spindle. Its installed length of 309 mm sets the distance between spindle flange and fastening point.

Benefits

• The 1/2 in square drive accepts standard sockets, so a change of fastener size only needs a new socket.
• Axial compensation with 50 mm spring travel and 30 to 93 N spring force absorbs height tolerances and the screw's travel while it is driven in.
• The offset output axis allows tight hole patterns and close spindle spacing at small screw distances, with a typical efficiency of 0.91.
• Designed to run maintenance-free for 1 million full-load cycles, which reduces line downtime.
• The installed length of 309 mm can be planned directly into fixture and stroke design.
