    The rack is a transmission component, mainly used to transfer power, and generally matched with the gear into the rack and pinion drive mechanism, the reciprocating linear motion of the rack into the rotary motion of the gear or the rotary motion of the gear into the reciprocating linear motion of the rack. The product is suitable for long distance linear motion, high  capacity, high precision, durable, low noise and so on.

    The application of rack:

    mainly used in various mechanical transmission systems, like Automation Machine, CNC Machine, Building Material Shops, Manufacturing Plant, Machinery Repair Shops, Construction works and so on.

    Rack Assembly

    To assemble connected racks more smoothly, 2 ends of a standard rack would add half tooth which is convenient for next half tooth of next rack to be connected to a complete tooth. The following drawing shows how 2 racks connect and tooth gauge can control pitch position accurately.

    With regards to connection of helical racks, it can be connected accurately by opposite tooth gauge.

    1. When connecting racks, we recommend lock bores on the sides of rack first, and lock bores by the sequence of the foundation. With assembling the tooth gauge, pitch position of racks can be assembled accurately and completely.

    2. Last, lock the position pins on 2 sides of rack; the assembly is completed.
