Custom Zerk for Track Tensioning System

Track Tensioning SystemSimplifies Lubrication, and Maintenance

Time is money when managing routine maintenance and lubrication of drive tracks on excavating equipment. A leading excavation machinery manufacturer designed a single zerk hydraulic system to deliver and bleed grease used to set/adjust track tension on their equipment. The system required a reliable and durable mechanism to inject lubricant, and then reverse pressure to allow the used lubricant to be flushed from the system and then recharged.

To make this work, the manufacturer turned to SafeWay. After close review and testing, SafeWay engineers identified and recommended two ways to improve durability and ensure leak-free performance: 1) Implement design and control features to minimize leak potential, and 2) Implement a dual hardening process to assure reliable performance of the zerk system’s body.

The excavating machinery manufacturer implemented our recommendations, which led to the system’s successful production and use. To this day, the single zerk hydraulic system continues to exceed expectations for performance, durability and cost.
