Hangzhou Unibear Industrial Co. Ltd|Hangzhou Unibear Holding Group Co. Ltd-Specialized Chain

Escalator Chain
- Twice precision punching technique for plate’s clinker after heat treatment, with little center distance fluctuation, hole’s burnishing band reaching 90%.
- Automatic milling for two sides of pin, preventing pin from twirling, ensuring straightness between two ladders’ pins.
- Hydraulic assembly machine, ensuring stable chain framework without warp occurred, and steady operation without noise.
- Imported heat & wear resistant grease, whose adhesive thickness over 0.2mm, greatly improving wear-resistance performance.
