Oilless bushes are also referred to as self lubricating bushes or bearings. that does not require traditional oil or grease lubrication. Instead, they use a variety of materials and designs to provide lubrication and reduce friction. Oilless bushes have become an important part of various industrial applications because of their ability to perform effectively without external lubrication. This is a revolutionary innovation in the field of mechanical engineering. The Oilless bushes provide an excellent alternative to lubricated bearings, reducing maintenance and operating costs while improving overall performance. Material for Oilless Bushes These bushes are typically made from a variety of materials, including: Porous Bronze Porous bronze bushes are made from a sintered bronze material that has been impregnated with a solid lubricant, such as graphite or PTFE.
Polyglyd bearings range defines the new advent in the era of sliding bearings which are made 100% from different derivatives of polymer components manufactured either through injection moulding or high precision machining of the extruded material. This range has excellent self lubricating features & wear resistance characteristics achieved through high strength fibres which also insures of the load bearing capacities. The special lubricants embedded in these range of bearings maintains the right friction coefficient friction as well an improvement of the service life. CROWN RANGE The self-lubricating feature of the Crown â?? CE bearing is achieved by adding solid lubricants and functional fibers into the body material and the friction coefficient is decreased by the solid lubricate grease immersion. The friction coefficient is affected by the load, operating speed and shaft roughness. The friction coefficient is generally decreased along the load increasing and increased along the operating speed.

It is mainly Used for high load and moderate speed application. BUSHES & PLATES CAN BE DEVELOPED WITH ANY SPECIFICATIONS AS PER CUSTOMERS REQUIREMENTS.
Dry Bushes are steel backed bronze impregnated bushes mainly used for High Load application upto 250 N/mm2 and temperature upto +280 C. MDU is a composite material consisting of three layers viz., steel backing (Low Carbon Steel), A Porous Bronze (90% Cu & 10% Sn) sintered Matrix, overlaid with a mixture of PTFE (Poly Tetra Fluro Ethylene) and Lead. Steel Backing provides the underlying strength while porous bronze sintered layer provides the strong mechanical bond for the impregnated PTFE/LEAD mixture. Crown Engineer is the best organization of manufacturer and exporter of bearing bush in India.
Sintered Porous Metal Bearings are powder metallurgical parts, the starting materials are obviously metal powder. The metal powder used are specifically produced to give flow and compacting characteristics and at the same time ensure best mechanical strength, grade or porosity for oil retention and self lubrication in its finished form. Material : SINTERED BRONZE / IRON SINTERED Range : Plain & Flanged Bushes, Self aligned Bushes, Solid Rod, Plate & different profile components as per drawings / samples. APPLICATION : Sintered Bronze Bushes are used for High Speed application ( up to 18000 rpm ) Iron Sintered Bushes are used for speed (upto 3000 rpm). Our firm specializes in offering an excellent range of Sintered Bronze Flanged Bushes. This innovative range of flange bush is widely demanded in various industries. Request A Quote
