Multi-Purpose Hydraulic Motor

MAHLE Original piston ring sets are designed for easy installation and immediate seating, virtually eliminating break-in time. They feature optimized ring materials, coatings, and tension for reduced friction and extended life. Compression rings have a barrel-faced contact area for efficient compression and a CNC-controlled gap chamfer to optimize compression and reduce blowby. Intermediate rings utilize a reverse twist design for superior groove side sealing and taper race machining for enhanced contact. The CP-20 oil ring assemblies incorporate a 20-degree ear angle for optimal side seal against the cylinder wall, with a special chemical polish on the oil ring expander promoting enhanced oil drainback. These sets offer unmatched quality and ease of installation, making them a preferred choice for engine builders.
