Hydro Bearings Material Composition

ATCORP specializes in producing a comprehensive range of high-performance, environmentally friendly bearings and bearing systems, renowned worldwide for their superior performance and innovative solutions. ShaftSlide™ is a specific products line, which are extensively specified across diverse industries such as Hydropower Turbines, marine, offshore, pump and other industrial sectors, underscoring their reputation for durability, efficiency, and sustainability in demanding applications.Manufacturing Process involves bonding long-lasting lubricating crystallites and extreme pressure particles to the surface of an interpenetrating polymer network (IPN), enhancing its durability and frictional properties. By anchoring these particles within the polymer matrix, the surface gains improved wear resistance, reduced friction, and increased ability to withstand high pressure conditions, making the material suitable for applications requiring enhanced lubrication and mechanical stability.

Benefits of Hydro Bearings

  • Environmental Friendliness:ATCORP ShaftSlide™ Water lubricated bearings eliminate the risk of oil leaks into waterways, which can be harmful to aquatic life and ecosystems.This is a major driver for their adoption in hydro power plants.
  • Reduced Maintenance:ATCORP ShaftSlide™ By eliminating the need for oil systems, water lubricated bearings simplify maintenance procedures and reduce the need for regular oil changes and seal replacements.
  • Cost Savings:While the initial cost of ATCORP ShaftSlide™ might be comparable to oil-lubricated ones, the long-term operational costs, particularly related to maintenance and potential environmental damage, can be significantly lower.
  • Enhanced Bearing Performance:Water lubricated ATCORP ShaftSlide™ can be designed with features like self-aligning segments and optimized groove patterns to improve performance and reduce friction.
