Honeycomb Bushing
Seamless Design with Honeycomb Structure: Features a seamless construction with a uniform inner wall pattern of conical blind holes, forming a efficient honeycomb lattice.
Self-Lubricating & Rapid Oil Film Formation: The grinding process generates lubricant naturally, ensuring immediate oil film formation on startup.
High Oil Capacity & Low Maintenance: Honeycomb pattern holds 3-5x more oil than standard grooves, enabling extended maintenance-free operation.
Uniform Lubrication, No Dead Zones: Fixed circumferential spacing ensures complete oil coverage across any sleeve size with minimal rotation.
Enhanced Durability: The honeycomb structure significantly increases load-bearing capacity and extends service life.
Patented Technology: Represents the latest generation in engineering machinery shaft sleeves (Patent No.: ZL201720260674.6).
