Concentricity and Cylindricity

Most manufacturers use centreless grinding techniques to finish the outside diameter but centreless grinding process does not take the inside diameter of the bearing into account, the centres of the outside diameter and inside diameter may not be the same.

GMP bearings are mounted on a mandrel and ground on a cylindrical grinder, thus achieving better concentricity as well as cylindricity to the full length of the bearing so that it is perfectly circular, perfectly straight and has no taper, as compared to bearings turned on a lathe machine.

Performance-Driven Advantages


  • Energy Savings : The GMP rubber formulation achieves an industry-low coefficient of friction, minimizing pump energy consumption without sacrificing performance. By reducing operational friction, our bearings lower energy losses, enabling significant savings over the lifecycle of the equipment.

  • Extended Shaft & Sleeve Protection : The advanced groove architecture integrated into GMP bearings creates a hydrodynamic lubricating film—even at low shaft RPM. This proprietary inner design maximizes water flow to flush out abrasive particles, safeguarding both the shaft and the bearing from wear and damage. Result: improved equipment longevity and operational efficiency.

  • Superior Vibration Absorption : Unlike rigid alternatives, GMP’s proprietary rubber compound exhibits superior damping properties, reducing vibrations transmitted from the shaft. Not only does this enhance operational silence, but it also minimizes structural stress, contributing to an extended service life across high-vibration facilities.
