Our Products
DU and DUB Type Dry Bush & Bearings (Oil Free) take advantage of the outstanding dry bearing properties of Polytetrafluoroethylene (PTFE) and combines them with strength, stability and good wear resistance, excellent heat conductivity and low thermal expansion. All our Bushings are sold under our "Dev Brand Engine Spares" Brand
DU Type consists of three bonded layers: A steel backing strip and a porous bronze matrix, impregnated and overlaid with the PTFE/ lead bearing material.
1. PTFE 0.010.03mm
2. Porous bronze 0.20.3 mm
3. Steel / Bronze backing 0.72.3 mm
4. Tin-plating 0.005 mm or
5. copper plating 0.008mm
DUB Type also consists of three layers: ---
Bronze backing replacing the steel backing strip. The structure is otherwise the same as that of DU. The bronze backing provides a high corrosion resistance, anti magnetic properties and a good thermal conductivity.
DU Bush, Bearings, Washers etc applications is suitable for:---

DX Type Bushings & Washers
Dx Type Dry Bushings (Marginal lubricated) It is made of high quality low-carbon steel, sintered porous bronze as its interlayer, with the compound of POM (POM-Pb) as its surface. And has good load capacity & wear-resistant. It's used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc. It is without lead, can meet the requirements of environment protection. All our Bushings are sold under our Brand
Our DX type bushings & washers are especially well-suited for applications where lubricant can not be supplied continuously or
repeatedly. Recommended for applications involving intermittent operation or boundary lubrication.

Foreign made DS Type bush may be operated without lubricant or under a trace of oil. It is of low friction, anticorrosion and is of long life. This is now applied in machines under oscillating motion and in open field or in corrosive environment such as hoisters, bulldogger, tower cranes, and printing or dyeing machines for textiles.
We are offering Aluminium Bronze Bushes to our client. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion. They are also resistant to corrosion in sea water.
Our core activity is Manufacturing “Centrifugal Castings” along with precision machining with the in-house machining facilities supplying both in Proof Machined and Machined Status. As we know that Centrifugal Castings are preferred over conventional castings due to its inherent qualities interms of near zero defects leading to higher reliability & strength.
