REV-41-1332-PK4 30 Tooth Plastic Gear - 4 Pack

5mm Plastic Hex Bore Gears are compatible with the REV DUO System and fit on a 5mm hex shaft. The hex shaft interface completely eliminates the need for expensive hubs or using potentially unreliable set screws. Gears 45 tooth and larger have a hole pattern on an 8mm pitch enabling easy mounting directly to DUO Extrusion, DUO Brackets, and other 8mm pitch systems. All DUO motion products have a uniform 15mm width to make quick design swaps fast and easy. Warning: Gears from other building systems may have a very similar tooth profile but are not an exact match. It may be possible to use the two gears systems together successfully in some situations, but it is not recommended.
