These are lightweight and low-cost straight gears. They are available in the J series with finished shaft holes and the F series with friction fastening, allowing for immediate use after delivery.

The "SSA flat gear" is a flat-shaped gear that has been lightened by cutting the boss. In addition to the J series with a finished shaft hole, we also offer the F series, which uses a bushing to fasten the shaft and gear through friction, and the hardened plus, which has high-frequency hardening added to the tooth surface. 【Features】 ■ Black oxide surface finish ■ Additional processing available ■ Machined finish *For more details, please refer to the catalog. Feel free to contact us with any inquiries.
