This is a thick-walled idler gear with 850 bearings. designed for increased durability in high-load environments.

The overwhelming response delivered by the white color!!
Uses top-grade materials. designed with high-level competition in mind.

High-precision design through precision machining ensures smooth operation.

��Faithfully reproduced involute curve (tooth profile) achieves smooth acceleration and response.
��The bearing fit is set slightly tighter to account for the expansion of the resin due to temperature rise during operation.
*850 bearings
(Outer diameter 8mm x Inner diameter 5mm x Thickness 2.5mm)
