Miba Industrial Bearings ZT Thrust and Guide Bearing

The Industrial Bearing Branch of the Miba Bearing Group produces hydrodynamic bearings and labyrinth seals for use in mechanical and plant engineering which are used in a wide range of high-performance applications. Our highly inspired teams, work diligently to serve our customers the best bearing solutions for each and every application. Content Side Description of the pedestal design 3 Bearing types and designations 9 Description of the pedestal bearing Miba ZT thrust bearings were designed to support high thrust loads. The modern design and high-performance standards ensure great...

Oil supply The bearing has been designed for an external oil circulation. If the lubricant supply fails, the thrust collar of the shaft delivers the lubricant from the oil sump to the oil scraper. The oil scraper delivers the oil to the radial and thrust parts. This system can be used to permit an emergency shutdown without damage in case an oil system failure occurs. The ZT bearings have an exclusive oil input for thrust pads and for each part of the two radial shells. Sealing The seals are selected according to the different operation conditions, environments and requested protection...
