CPC large slide rail data

The CPC AR/HR series standard ball linear guideway system is engineered for industrial automation applications demanding high load ratings, exceptional torsional stiffness, and high operational reliability. Adopting an O-type 45-degree contact angle arrangement across four circulating ball rows, it delivers balanced load capacity in all directions.

1. Core Design Highlights

• O-Type Ball Arrangement: 45-degree contact angle creates a wide effective support span, providing superior resistance against moment loads ($M_x$, $M_y$, $M_z$).
• High Dynamic Load Capacity: Optimized raceway curvature and oversized steel balls substantially increase basic dynamic ($C$) and static ($C_0$) load ratings.
• Comprehensive Sealing: Dual-lip front end scrapers, side scrapers, and bottom seals block grinding dust, swarf, and coolant splash.
• Built-In Lubrication Pad: Self-lubricating storage inserts continuously replenish oil film on raceways, extending maintenance intervals to over 5,000 km.
