Merit 160940 Upper Bushing for Rammer 2577 | Merit Premium Quality

Why Choose Merit 160940 Upper Bushings?

In demanding demolition and quarrying environments, the upper bushing plays a critical role in protecting the most expensive part of your hammer: the piston. Merit spare parts deliver:

1. Piston Protection and Precision Alignment

A worn upper bushing allows the tool to deflect from its axis, leading to "oblique blows" (off-center strikes). This is the leading cause of piston chipping and internal oil leaks. The Merit 160940 Bushing guarantees a tight, precise fit, keeping the piston’s strike path strictly centered.

2. Superior Heat and Friction Resistance

The operation of a Rammer 2577 generates colossal thermal energy. Our bushings undergo a specialized finishing process that prevents galling (metal-to-metal welding), ensuring smooth tool movement even during continuous high-temperature operation.

3. Structural Integrity and Strength

By using forged alloy steel instead of standard cast iron, our bushings possess superior fatigue strength. They are engineered to withstand constant vibration and shockwaves exceeding 12,000 Joules without developing internal stress fractures.

🛠️ Maintenance Tip: Monitor Your Tolerances

When the gap between the working tool and the 160940 upper bushing exceeds the maximum wear limit specified by Rammer, it is time for a replacement. Timely bushing maintenance is a low-cost procedure that prevents the catastrophic failure of a high-value piston.
