INTRODUCTION:  The Company produces micro self-oiling bushings of high precision and low noise and powder metallurgical pieces that are based on copper, iron copper and iron, which used in telecommunication equipment, computers and IT equipment, household electrical appliances, instruments and meters.  The Company makes more than 450 million self-oiling bearings a year, which are mainly employed in vibrating, light-driven, fan-used and toy motors that require high precision and low noise. 30% of products are sold at domestic market while 70% exported. The measurement precision of products is controlled within 0.005mm and different degree of bearings within φ0.02mm. Products' quality tallies with Japanese Industrial Standards and China's GB Standards, thus reach world's advanced level. The products are up to the Chinese and Japanese standard (GB&JIS).  The types of products are as follows: 1. Small oil-impregnated bushings for copper-based, iron-copper-based, iron-based.  The shapes are as cylinder, flange, sphere, collared sphere.  The range of the size is as follows: ID:Ø0.6-Ø12mm, OD:Ø1.2-Ø18mm, L:0.7-15mm; 2. Small precise mechanical parts of copper-based, iron-copper-based, iron-based.  The range of the size is below 18mm. According to the classify of the material, the using fields also can be divided to several parts: 1. copper-based, used in ventilator, office machinery, starter, dynamoelectric tool and aero-transport; 2. iron-based, used in the low-velocity and high-pressure environment; 3. iron-copper-based, used in high-velocity and high pressure environment; 4. iron-copper-pb-based, used in middle(high)-pressure and middle(high)-velocity environment, similar to the copper-based. As the leader of self-lubricating bushing manufacturers in China, we recognize high quality, competitive price and best service as the crucial factors for a successful corporation.  Here advanced technology, equipments and management system are widely adopted to ensure the soonest delivery and first-class quality.
