Product Description

Bearing Wholesalers sales high quality aftermarket OEM style mud pump spares, mud pump consumables, mud pump expendables, and mud pump parts. . Our mud pump expendables, mud pump replacement parts and mud pump spares are competitively priced, offer exceptional quality and durability. Manufactures include; Brewster, Continental Emsco, Gaso, Gardner Denver, Ideco, National, Oilwell, OPI, Skytop, and Wheatley.. The Hex 240 Pump (National Oilwell Varco patent) is designed to handle variable pressure and volume flows. Like the old pumps, it utilises axial pistons, but instead of a swashplate it has an asymmetric cam. Significant advantages over triplex mud pumps are: • 30% smaller • 30% lower weight • greater pumping capacity • steady flow (no pressure pulsations) In Nov 2000, the first contact was established between National Oilwell Varco and INA (linear bearings), as well as FAG (rolling bearings). In May 2001, the first prototype bearings were ordered. In 2004, the first series of bearings was produced. INA/FAG supply all the bearing components for the Hex 240 Pump. Extreme loads and constant wear characterize the brutal operating environment of a typical drawworks system. Oilfield Equipment Bearings are well-suited to these applications, due to optimized internal geometry and improved surface finishes that increase bearing performance. Spherical roller bearings can also manage high radial loads even when misalignment, marginal lubrication and contamination are present – all common challenges in a drawworks system. For chain-driven drawworks, Bearing Wholesalers provides a complete offering of roller chain that meets API requirements, and resists fatigue and wear. Customers can order chain cut to the exact length required for the job to avoid scrapping chain. Timken offers a full package of products to help support improved uptime in the drawworks, and, more importantly, build a high level of confidence that the equipment can handle the job.
