November 30, 2015 - Parker upgrades GOLD CUP pumps with bearing cages that feature a larger, thicker and more robust cage construction for double the strength of a standard barrel bearing.
Parker GOLD CUP hydrostatic piston pumps have long featured a rugged barrel bearing that outperforms shaft bearings and meets the needs of most applications. However, new Tier 4 engines with increased torsional acceleration and vibration, coupled with greater demands for increased machine productivity, can deteriorate component life in challenging applications.
In response, Parker has expanded its bearing offering for small-frame size 6/7/8 GOLD CUP pumps with improved bearing cage designs that enable maximum productivity and dramatically improved pump life in severe-duty environments.
The Severe Duty barrel bearing features a larger, thicker and more robust cage construction for double the strength of a standard barrel bearing.
All the benefits of the Severe Duty bearing are also found in the Extreme Duty barrel bearing while running with low-viscosity and exotic fluids and accommodating higher temperature demands. It features a single-piece bronze cage that provides the greatest strength and lowest friction on the market. It is ideal for severe heavy-duty applications in the mining, oil and gas, and military industries. Importantly, the Extreme Duty bearing is available for all Gold Cup frame sizes.
