  • Bearing Roller Conveyor Chain

Anti-dust Specifications

Has the same dimensions as standard RF conveyor chain with R or F rollers. Labyrinth construction and seals make it difficult for dust to penetrate the rollers.

This gives Anti-dust Series 3x the wear life of Standard Series in dusty environments.

Available with DBR or DBF rollers.

Operating temperature range: -10ºC to 80ºC

Standard Series (Anti-dust Series)

1. Structure & Features

Conveyor chain with cylindrical bearings between the rollers and bushes. Has the same dimensions as general use conveyor chain with R or F rollers.

Note:
1. DT Series: General Use Conveyor Chain, AT Series: Heavy Duty Conveyor Chain
2. The base chain cannot be used to convey when fully covered in dust.
3. Periodically lubricate the base chain using the grease nipples on the pin heads.
4. Base chain is interchangeable with General Use Conveyor Chains and can use any existing sprockets.
5. Do not use in corrosive environments (in contact with water, underwater, etc.).
