As industrial equipment continues to develop toward higher reliability, longer service life, and higher protection levels, the use of stainless steel grease distribution blocks in centralized lubrication systems is steadily increasing. This paper focuses on seven typical stainless steel models from CISOLUBE—DSP, DSPP, DXF grease distribution blocks, and VL‑1, VL‑1X, VL‑1XL, VL‑11 grease injectors. It systematically analyzes the material advantages, structural characteristics, and technical parameters of stainless steel products, and evaluates their applicability in different lubrication systems. The results show that stainless steel grease distribution blocks offer superior corrosion resistance, temperature stability, metering accuracy, and ease of maintenance compared with traditional carbon‑steel versions, providing higher material reliability and long‑term value.
Centralized lubrication systems are widely used in modern machinery, with the core function of delivering lubricant accurately and continuously to multiple lubrication points. Traditional carbon‑steel grease distribution blocks have a short service life in humid, high‑salt, large‑temperature‑difference, or corrosive environments, and are prone to sticking, rusting, and clogging. As the reliability requirements of industrial equipment increase, stainless steel progressive‑type grease distribution blocks and stainless steel single‑line grease injectors have become the preferred alternatives—especially in pharmaceuticals, offshore platforms, food, sugar processing, agricultural machinery, port equipment, mining equipment, wind power, and heavy‑duty industries.
Stainless steel forms a stable oxide protective layer through its alloy structure, resisting humidity, salt spray, mild acids/alkalis, and heavy‑pollution environments, significantly extending service life.
Even under high cycling frequency and high temperature, stainless steel maintains stable fitment without deformation or fatigue damage.
Its smooth surface prevents dirt accumulation and complies with hygiene requirements in the food and pharmaceutical industries.
With strong wear resistance and low susceptibility to abrasion caused by impurities in lubricants, stainless steel is ideal for long‑running equipment.
The CISOLUBE SSV grease distribution block adopts an integrated structure and is especially suitable for equipment with limited installation space. Stainless steel construction ensures stable cycling even in harsh environments.
