General Metals & Polymers

General Metals & Polymers is a manufacturer and exporter specializing in Water Lubricated Bearings. GMP has been supplying Water Lubricated Bearings to the marine industry, pump manufacturers, power plant’s, their OEM’s, OMS’s & maintenance companies all across India, Middle East, Europe and Australia for over 30 years. GMP is the first Indian company to indigenously develop Water Lubricated Bearings for the Indian Navy in 1981 Our range of water lubricated rubber bearings for Vertical Pumps, Propeller shafts and Rudder shafts are available in metal or non metal range, covering a wide range of shaft diameters from 25mm to 400mm. (bespoke sizes can be made on request) The offered range of water lubricating bearings is available in standard and non standard sizes. GMP Water Lubricated Bearings are available in Cylindrical and Flanged Sleeve. The inside rubber lining is Fluted or Spiral Fluted in Circular or Polygonal Profile. Available in metal or composite outer sleeve with Nitrile or Neoprene rubber lining.

GMP Composite shell water lubricated Bearings offer all the benefits of our brass shelled bearings with added benefit of being lightweight (1/3 the weight of brass bearings) and no galvanic corrosion due to its anti-electrolytic properties.

GMP Composite shell water lubricated bearings are made of proprietary composite materials developed by our in house R&D team. The material is resistant to oil, grease and chemicals and match the temperature range of metal bearing materials.

High temperature resistance and negligible swelling characteristics of GMP Composite shell water lubricated bearings enable them to operate at a closer running clearance than other bearing materials.

The composite outer shell is kept flexible for better grip when pressed into the housing. Our shell material also has bearing properties, so even if the soft lining is worn out the shaft will not be damaged.

GMP Composite shell water lubricated bearings are available in brown and black colours. GMP Flanged Composite shell water lubricated Bearings is available only in black.

GMP Flanged Water Lubricated Bearings are ideal for very heavy axial loads. Our Flanged Water Lubricated Bearings are cast centrifugally with an integral flange, these shells are heavy walled. The flange provides structural strength to retain bearing and prevent rotation in housing. Shells are furnished un-drilled unless specified. These are available in solid and split design.

Specifications:

• Material: Naval Brass/Gun Metal/Stainless steel
• Diameter: 25 mm to 400 mm
