LEGO® Technic Gear Rack 1x7 87761

Create controlled back-and-forth movement with the LEGO® Technic Gear Rack 1 x 7 (87761). This compact rack features a row of gear teeth that can mesh with compatible Technic gears, converting rotary movement into linear motion for functional LEGO® mechanisms.

Compact Rack for Moving Technic Builds

Part 87761 is particularly useful when a mechanism needs to slide rather than simply rotate. Its integrated connection points make it easy to incorporate into Technic structures while the toothed rack provides the working surface for a rack-and-pinion mechanism.

• Part number: 87761
• Size: 1 x 7
• Type: Technic gear rack
• Function: Converts rotational movement into linear movement
• Connections: Includes Technic axle and pin connection points
• Useful for: Steering, sliding mechanisms, extending assemblies and custom mechanical MOCs

Build Rack-and-Pinion Mechanisms

Pair the rack with a suitable gear to create compact steering or sliding functions. It can be incorporated into vehicle steering assemblies, mechanical linkages and other Technic projects where accurate linear movement is required.
