Advantages Oval Liner.

• Suitable for high torque
• No gap between liner and barrel with special paste in between for perfect heat transfer
• One piece solid and trough hardened steel

Optimum cooling system for barrels

-Bores for barrel cooling are loccated as close as possible to processing bores

- Minimum pressure drop to special design

- Optimized flow of cooling water
