Product Features
 
Feature 1: The round rack has a circular shape, suitable for certain special operating conditions
Feature 2: The circular design ensures accurate and smooth reciprocating motion of the rack
Feature 3: You can choose racks made of regular steel or stainless steel according to actual operating requirements.
Feature 4: The rack length can be specified according to your needs, and for easy installation, you can choose to add holes at both ends.
 
Usage Method
 
■ Linear Motion: Rack and Pinion Drive
Bracket Micro Gear Type Slide Table Assembly
Case 1: Linear Motion Using Gear and Rack Drive
Positioning Mechanism for Basic Frame
Case 2: Linear Motion Using Gear and Rack Drive
 
Precautions
 
■ Cutting Method for Rack End Face
Screenshot of Rack End Face Cutting Method
Cut according to the length of the effective number of teeth (tooth root)Cut from the reference surface to the specified length, excluding the teeth.

■ Rack Connection Method
The end face machining accuracy of MISUMI racks is less than the pitch.
Therefore, please leave a gap between the two racks as shown in the diagram below, and connect them after adjusting the pitch using a combination rack (racks with the same module).
Rack Connection Method Instructions
 
Example of Use
 
Case Study: Round Belt Conveyor for Transporting Lightweight Items
Equipment Name: Lifting Mechanism Using Circular Rack and Pinion

Feature 1: Uses multiple round racks meshing with gears for multiple linkages, enabling the lift to move up and down.
Feature 2: Use one cylinder to move multiple lifters up and down.
Feature 3: Enables lifting multiple workpieces at once.
Feature 4: Three round racks and gear assemblies can be mounted on the same part. When installing the gear, adjust the position to reduce backlash.
