Precision Tapered Roller Bearing

  • Item#: 399A-90187
  • Mfr#: 399A-90187
  • UPC: 05389302960
  • Greater rotational accuracy because of tighter manufacturing specifications
  • Increased accuracy and rigidity from special internal geometry and reduced bore and OD tolerances
  • Exact specifications are met with strictly machining and assembly processes
  • Fatigue life is enhanced with a tapered roller bearing's high load-carrying capability compared with other bearing types
  • Operating torque and temperature can be precisely controlled with the adjustable setting of a tapered roller bearing
  • Holes provide additional lubrication to the bearing
  • Bearing bore, OD, width or radius have been customized to be different from the basic part number, and are not interchangeable

DESCRIPTION

With more than a century of knowledge and innovation, Timken is an industry-leader in designing, manufacturing and applying high performance engineered bearings into our customers’ most challenging applications. With one common global quality system across all manufacturing plants, we deliver consistent product performance and reliability anywhere in the world. As a Timken customer, you are connected to a team of application, sales and on-site service engineers who help solve unique equipment challenges resulting in extended uptime, productivity and efficiency. We are the recognized global leader in tapered roller bearings with the most extensive offering in the market of inch and metric sizes and assemblies fitting shafts of 8mm to 1270 mm. With capacity to manage both radial and axial loads, Timken® tapered roller bearings are made with various angles and roller lengths to provide a wide range of radial and thrust ratings for optimizing envelope size, minimizing weight, and improving system efficiency. Timken® tapered roller bearings feature precision tolerances, proprietary internal geometries and premium materials for superior durability in millions of demanding applications. Some applications demand a high level of precision that cannot be achieved with standard tapered roller bearings. This includes many machining, printing press and rolling mill applications where combinations of tight tolerances, high speeds and radial and thrust loads are present. The more demanding the precision objective, the more accurate the bearing must be. Timken provides four precision classes, in both metric and inch systems, that cover the full range of precision application requirements. Precision Tapered Roller Bearing Assembly; Imperial Series; 2.6875in Bore; 4.3307in OD; 2.0625in Width; Open; Cylindrical Bore; Steel Cage; Precision ABMA Class 3
