Volume Discount

Worm gear with curved tooth tip corners and mirror-finished tooth surface by precision rolling finish to prevent damage to the worm wheel teeth.
[Features]
· Gears with module 0.5 to 3 have precision rolling finish, SUS304 and S45C with excellent corrosion resistance.
· Modules are 0.5/0.8/1/1.5/2/2.5/3
· The surface of the threaded side has improved hardness by work-hardening, and the fiber structure of the metal is not cut off, resulting in excellent mechanical properties.
Normal module. To be used in combination with a worm.
[Applications]
· Ideal for power transmission, drive, and conveyance parts of equipment.
· Used when deceleration is required

(i)Caution

The product images are representative only. Specifications may vary by part number, including shape and color.
Delivery dates are unstable due to difficulties in obtaining materials and components. There is no estimated date for the next restock of items that are currently unavailable for order.
The worm and worm wheel should be used in the same module, in the same direction of twist, and with the same number of teeth.
