Stainless steel ball transfer unit PV-H

polymersteelplastic

Overview
Conventional ball transfer is structurally prone to retain dust inside, causing rotation failure in harsh environments such as underwater (sea water, muddy water), oil, and dust. Planeveyor dust discharge type uses the original spherical surface (PAT.P) to provide holes/slits in the receiving part of the small balls and the ball cover to discharge dust and water that get inside, enabling continued smooth rotation even under severe conditions.

Key features

• Original spherical surface (PAT.P) enables drilling of multiple dust-discharge holes.
• Discharges dust and water entering the mechanism to prevent rotation failure.
• Fundamental approach different from seals or other countermeasures; relies on internal discharge rather than exclusion.

Comparison
Conventional (Atec's old type): Tends to allow dust intrusion and is disadvantaged in harsh environments (underwater, oil, dust).
The original spherical surface (PAT.P): Discharges dust that enters and demonstrates reliable performance in harsh operating environments.

Examples of harsh usage situations corresponding to dust discharge type

• Transportation of an iron plate with mill scale
• Transportation of a mold (sand mold)
• Stone processing site (sandblasting)
• Powder molding machine (mold movement)
• Work pieces conveyance in washing machine
• Work pieces conveyance in cutting process
• Ceramic powder molding machine (molding of glass fiber)
