NIPPLE, GREASE

BG 002 031 45A NIPPLE, GREASE A NIPPLE, GREASE, often called a zerk fitting, serves as a one-way valve designed to facilitate the injection of lubricant into mechanical components. It's a fundamental part of any preventative maintenance schedule, allowing technicians to deliver fresh grease to bearings, bushings, and pivot points. Without these fittings, proper lubrication of many moving parts on a drill rig would be impossible, leading to increased friction and heat.

You'll find these fittings strategically placed throughout the drilling rig, wherever components like boom linkages, feed beam rollers, or drifter guides require regular greasing. Their function is vital for the overall reliability and lifespan of expensive assemblies. When components receive adequate lubrication, they operate more smoothly, experience less wear, and are less likely to fail unexpectedly, which directly contributes to consistent drilling performance and reduced downtime.

Failure symptoms typically include grease not entering the component when pumped, or grease leaking out around the fitting. A blocked nipple means lubricant isn't reaching the bearing, leading to accelerated wear. If a NIPPLE, GREASE is bent, broken, or its threads are stripped, it needs to be replaced immediately to ensure proper lubrication. Regular inspection and replacement of damaged fittings are simple, cost-effective steps to prevent major mechanical failures.
