Product Introduction
The Sleeve without oil hole is a revolutionary solution engineered for precision cooling in industrial machinery and equipment, eliminating the limitations of traditional oil-lubricated or fixed-direction coolant systems. Designed with a specialized hollow structure and oil-hole-free configuration, this sleeve integrates advanced thermal management with maintenance-free operation-addressing the dual challenges of efficient heat dissipation and contamination prevention in critical workflows.
Crafted from high-performance materials (available in reinforced silicone or industrial-grade steel), the sleeve boasts exceptional durability with a temperature resistance range of -65°F to 350°F (-54°C to 177°C) and compliance with RoHS, PFOA, and PFOS standards . Its universal design accommodates diverse equipment sizes (inner diameters ranging from 6mm to 32mm) and integrates seamlessly with existing coolant systems, making it a versatile upgrade for both retrofits and new installations . Unlike conventional sleeves that rely on oil lubrication (and associated oil holes), this product leverages solid lubrication modules and adjustable coolant flow to deliver consistent performance without leakage or environmental contamination.
Features
Adjustable Coolant Direction
Equipped with an EZ-Adjust structure, the sleeve allows 360° fine-tuning of coolant flow to target high-heat zones precisely. This unique design ensures smooth, unobstructed coolant delivery-reducing friction-induced wear by up to 40% compared to fixed-direction alternatives.
Oil-Hole-Free Clean Operation
The absence of oil holes eliminates risks of lubricant leakage, making it ideal for cleanroom environments (e.g., medical device manufacturing) and food-grade machinery. Solid lubrication blocks embedded in the inner sleeve provide long-lasting lubrication without maintenance.
High Rigidity & Durability
Constructed with reinforced polyester layers or high-strength steel, the sleeve resists deformation under high pressure (up to 30 psi) and extreme temperatures. Its smooth finish minimizes debris buildup, extending service life by 2–3 times that of standard sleeves.
Universal Compatibility
Available in multiple inner diameters (6mm–32mm) and customizable lengths, it fits milling chucks, micro bars, borehole pumps, and electronic device cooling systems. The sleeve is compatible with most industry-standard coolant types (water-glycol, synthetic coolants).
Applications
Precision Machining
Used with micro bars and milling tools to cool cutting zones, improving tool life and part accuracy. Compatible with Kyocera EZ Bar systems and similar precision tooling.
