The TSUBAKI PX Lock Pulley S Type P8M15AF in aluminum is a lightweight timing pulley with an integrated keyless lock. The aluminum body reduces inertia for fast acceleration in servo-driven systems, while the lock grips the shaft without keyways. It is used in robots, indexing tables and high-speed automation drives.
