Self-lubricating Bronze Guide Sleeve

Definition

As a key component of the mold guiding system, this bronze graphite self-lubricating guide sleeve is made of high-quality materials, with military-grade precision and innovative technology. It provides stable, wear-resistant and maintenance-free guiding solutions for various molds, effectively protecting the punch and die, significantly improving the processing accuracy and service life of the molds. It is widely applicable to complex working conditions in multiple fields such as automotive molds, metallurgy, injection molding machines, construction machinery, and ships. It is exported to major markets worldwide, including Europe, Asia, Southeast Asia, Japan, and South Korea.

Core materials and structure create hardcore quality
The product is based on C93200 tin bronze (CuSn7Pb15), and is embedded with high-purity graphite solid lubricant with a purity of ≥ 99.9% (in accordance with ISO 8002 standards). The oil content is ≥ 20%. It breaks through the limitation of traditional bearings relying on oil film lubrication, and can still effectively reduce friction and wear in oil-free lubrication, high-temperature, and high-pressure harsh environments. The overall integrated design integrates the function of flange edge positioning and positioning hole processing, suitable for various complex working conditions such as high pressure, low temperature, and closed structures, and is compatible with SKD61/SKH51 and other high-hardness guide pins without pressure, with extremely strong adaptability.

Four core values define new industry standards
Dual-efficiency self-lubrication with ultra-low friction
The embedded graphite lubrication structure achieves dual-efficiency self-lubrication, with a friction coefficient as low as 0.08. No additional lubricants are required, reducing maintenance costs and downtime. It maintains stable operation even in dry friction conditions.
Military-grade precision, ultimate accuracy
The inner hole tolerance is controlled within ±0.003mm, and the straightness is ≤ 0.005mm/100mm. The ultra-small mating gap ensures the high precision of mold movement, improving product processing accuracy from the source.
Extremely long service life, wear-resistant and durable
After 1 million reciprocating tests, the wear amount is less than 0.01mm. In the stamping mold scenario, the service life exceeds 2 million strokes, significantly reducing the frequency of mold component replacements and improving production efficiency.
Intelligent heat conduction, anti-sticking and anti-blocking
The thermal conductivity is as high as 60W/m·K, enabling rapid heat dissipation during operation, avoiding component sticking problems caused by excessively high temperatures, and ensuring continuous and stable operation of the equipment.

Three technological breakthroughs enhance the user experience
1. Gradient copper layer structure: Achieves a gradual transition from a high-hardness surface layer to a ductile matrix, balancing surface wear resistance and overall impact resistance, meeting the requirements of high-frequency and high-load mold operations.
2. Intelligent lubrication system: Equipped with laser micro-hole oil storage technology, the retention rate of lubricant increases by 40%, further extending the lubrication cycle, and making oil-free lubrication more sustainable.
3. Anti-scraping and dust-proof design: Optional inclusion of a built-in scrap removal ring structure, effectively blocking dust and iron filings from entering the guide sleeve interior, preventing component wear and protecting the guiding accuracy.
