1. Freebear Standard Ball Transfer Units (Mechanical Series):
These are precision-engineered mechanical components designed to convert sliding friction into smooth rolling friction. Equipped with a large main ball supported by smaller circulating balls, they allow effortless 360-degree omnidirectional movement and rotation of heavy workpieces, plates, and cargo on conveyor tables and workstations.

2. Freebear AFU Series System (Pneumatic Die Lifters):
This is an advanced air-driven automated lifting and positioning system. It features integrated pneumatic piston tracks that raise multiple ball rollers simultaneously when industrial compressed air is supplied, lifting heavy press dies, molds, or jigs for quick tool changeovers. The rollers safely retract under the heavy load as soon as the air is exhausted.
