Brand

Since its establishment in 1986 as a professional manufacturer of internal parts for hydraulic breaker hammers, BKS.B.C.T has developed and produced Diaphragm, Polyurethane damper, oil seals, and various other products, and continues to contribute to the field of hydraulic breaker hammers.

 

KEDIAS oil seal inherits 100 years of sealing technology and experience, and its products are exported to various parts of the world, gradually becoming a globally renowned brand. Through the unremitting efforts and innovation of KEDIAS company, we have developed more durable and suitable sealing materials for various harsh working conditions, focusing on providing you with comprehensive hydraulic sealing system solutions!

Based on material development, combined with decades experience on seals design, production and application, and verified with professional laboratory and bench testing, TIANJIN PARKER has provided partners including hydraulic and pneumatic systems with the optimum sealing solutions.

We have independently developed the KEDIAS brand Breaker hammer seal and jointly developed a sealing structure with high temperature resistance, ultra wear resistance, and longer service life with the School of Materials at Hebei University of Technology. Its unique formula and processing technology greatly solve many problems of oil leakage during the use of the crushing hammer, reducing the strain phenomenon of the products in the Breaker hammer main factory.

Since its launch in 2016, the KEDIAS brand has been recognized by domestic and foreign customers. Word of mouth is constantly rising. Breaking the long-term monopoly of foreign brands on sealing products in China, greatly reducing the cost of customer installation and after-sales service. And establish a long-term and reliable strategic partnership with customers.

Its KUS, BUE, and EUD are three main oil seals,Different design concepts, made of polyurethane

PU polyurethane oil seal is a type of Casting Polyurethane seal, which is a thermosetting elastomer material. A synthetic material intermediate between plastic and rubber, formed by the reaction of polymer polyols and isocyanates, extending and cross-linking.

Polyurethane oil seals have the original elastic properties of the material, and have sealing properties such as chemical corrosion resistance, high elasticity, high pressure resistance (hardness), tensile strength, tear resistance, radiation resistance, shock absorption and buffering. Its excellent comprehensive performance can maintain good elasticity over a wide hardness range, which is unique to ordinary oil seal components. And PU polyurethane oil seal is mainly used for hydraulic cylinders to buffer or reduce vibration between mechanical equipment friction. Its sealing components are easy to install and can scrape away dust adhering to the piston rod. PU sealing is generally suitable for shock absorption of metallurgical, mining, petroleum, automotive, building materials, sports, heavy machinery, and large stamping equipment.

The profile is single-acting rod sealing consists of a slipper PTFE ring and elastomer as a preloading element, particularly suitable for sealing rods in control servo as sited equipment and quick acting cylinder, optimal sealing performance will be obtained if the rod sealing set is usd in tandem with a double wiper. the material PTFE and the Oring make the product suitable for a wild range of applications.

NOK in Japan - a pioneer and sharer in the world sealing industry. NOK Corporation was founded in 1939 and is one of the earliest oil seal manufacturers in Japan. It is one of the world's largest sealing manufacturers, with NOK products occupying over 70% of the market in Japan and over 50% in other countries.

NOK has always maintained a leading position in technological research in the world's sealing industry, with most of the research not conducted by its predecessors, turning many 'impossible' into 'possible'. In the 1950s, the "Lubrication Theory of Oil Seals and Seals" was not the first to explain the sealing mechanism in theory. The high-temperature and high-pressure resistant polyurethane synthetic rubber developed in the 1960s has obtained world patents.

NOK products are widely used in general industry, enterprise industry, heavy machinery, and engineering machinery industries.

PARKER,Chinese name (short for Parker Hannifin) Parker Hannifin, the world's leading diversified manufacturer of motion and control technologies and systems, providing precision solutions for a wide range of transmission control, industrial and aerospace markets, has now become the world's largest company specializing in the manufacture and sale of a wide range of refrigeration air conditioning rubber parts, hydraulic, pneumatic and fluid control products and components global company
