Material and heat treatment: EGW20SB rails are made of high-carbon chromium bearing steel, which is carburized and hardened and low-temperature tempered. The surface hardness reaches HRC 58-62, the core remains tough, and has strong impact resistance.
Reinforced structural design: Increased ball diameter and multi-row cyclic arrangement (such as 4-row ball) significantly improve static/dynamic rigidity and support higher loads).
Integrated lubrication system: standard grease holes and oil storage structure, compatible with automatic lubrication system, reducing the frequency of manual oiling. Some models are equipped with sealed end covers to prevent grease leakage.
Sealed and dustproof: multi-layer scraper and end face sealing design effectively block dust and debris intrusion. EGW20SB is suitable for harsh environments such as woodworking machinery and clean rooms.
