FALOGEAR Brand Factory Direct 8-Speed Manual Gearbox JS125T-1701140 Synchronizer Double Cone Main Bo

JS125T Double Cone Synchronizer for Manual Gearbox

The JS125T-1701140 is a double cone synchronizer assembly designed for 8-speed manual gearboxes used in forklift transmissions and industrial drive systems. The double cone design provides twice the friction surface area of a single cone synchronizer, enabling faster, smoother gear engagement with reduced shift effort — particularly important in forklift applications where frequent forward-reverse directional changes and gear selections occur throughout the work shift.

Manufactured from high-grade alloy steel with precision-machined friction cone surfaces and hardened engagement teeth, this synchronizer assembly ensures reliable speed matching between the gear and shaft before dog clutch engagement, preventing gear clash and extending transmission component life. The brass synchronizer rings feature machined oil grooves that maintain a consistent lubricant film for smooth operation and heat dissipation.

Designed for JS125T series transmissions and compatible with similar 8-speed manual gearboxes used in select forklift drive systems. Verify transmission model and synchronizer dimensions before ordering.
