Industrial Products - 4918 TIMKEN AEROSPACE BEARINGS AND PRECISION COMPONENTS

While based on standard configurations, aerospace bearings are designed to meet the unique requirements of the industry. Most bearings used in aerospace applications are made from vacuum-melt 52100 or VIM-VAR M-50 and are normally manufactured to ABEC/RBEC 5 tolerances with high-strength machined cages. Other special materials are available for performance enhancement. Standard configurations are available in sizes from 10mm bore to 300 mm OD with special designs up to 600 mm OD.

Ball Bearings for Aerospace Applications

Various ball bearing configurations areavailable for aerospace applications and are specially designed to handle radial, thrust, moment, reversiblethrust or combination loads as required. Bearings may be supplied as single units or in preloaded sets.There are two basic Conradconstructions. The HK series is designed to handle radial, thrust, moment, reversible thrust or combination loads. It also has high- strength Conrad separator options that can manage severe loads and speeds. The HD series, with its innovative fractured outer ring design, allows for maximum ball complement in a radial deep-groove bearing. This provides significant improvements in dynamic load capacity and predicted service life.Two angular contact configurationsare available. The HA series is a non- separable design with counter-bored outer rings and one-piece, high- strength separators. It is used in preloaded and/or thrust-type applications. Options include deep- groove outer and relieved inner races for ultra-high-speed applications. The high-performance HT series, with full deep-groove outer rings, one-piece, high-strength separators and two extra-deep-groove inner ring halves, is typically used on high-speed shafts with reversing thrust loads.
