〇 Product description

A metal solid differential axle set compatible with speed-increasing bevel gears for Ketsukaki.

By changing the solid cup and solid housing to metal, it supports higher rotation and higher load.

Use [R31W212] one-way & solid ring gear for the ring gear.

By using the separately sold [R31W243] gear spacer set, it is possible to support our company's speed-increasing bevel gears (17T / 18T) for Ketsukaki.

* Please check the list below for the number of gear spacer sets and the number of teeth of the corresponding bevel gear.

* If you are looking for a rigid axle that supports deceleration bevel gears, please purchase the [R31W270] GRK Rigid Axle Set (for deceleration gears).

* A shim with an inner diameter of 10 mm is required to adjust the clearance between the gearbox and bearings and to adjust the final backlash.
