forming a complex, winding and narrow maze between inner and outer seal part.
The maze is filled in high quality grease.
Outstanding performance of durable water proofing/dust proofing.
So rollers we produced can be rotated neatly with outstanding performance of water-proof and dust-proof.

Roller adopt C3 deep groove radial ball bearing which adopts bidirectional seal structure
to improve the performance of water-proof and dust-proofing.

Parameters of the tube and shaft rollers adopted accord with GB standard requirmenets.
The tolerance as radial jump, roundness, straightness and appearance surpass the strict requirements in GB standard.
The housing is produced by the cold-rolled plate drawing,
adopting both sides precise welding between housing and shell to guarantee the rollers strong and rigid.
