Fafnir angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance. Double-row Conrad bearings can accommodate thrust in both directions. The special geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads. Different designs offer contact angles ranging from 20° to 40°. Higher angles provide more axial load capacity for longer service life operating under axial and radial loads.

Fafnir superprecision ball bearings are designed to meet demanding machine tool requirements for high speeds, accuracy and rigidity. These bearings are available manufactured to ABEC-7 and ABEC-9 tolerances, the most precise tolerances recognized by the ball bearing industry. Most superprecision ball bearings have contact angles of 15° or 25° for different combinations of radial and axial loads. Special raceway finishes and ball bearing designs achieve the highest possible operating speeds. Hybrid ceramic bearings are available with steel rings and ceramic balls for special applications involving high speeds and other demanding requirements. Ballscrew support bearings are supplied in sets with 60° contact angles and a maximum ball complement for the high capacity and axial rigidity required for the most precise tool positioning.

Fafnir control bearings generally consist of an inner and outer ring with a complement of precision balls, a seal or shield and, in some cases, a cage or separator. These bearings are typically used in flight control surfaces. The full-complement type is intended for applications requiring high loads and oscillating motion. The cage-type is intended for low torque, lighter loads, intermittent rotation and long life. Fafnir control bearings are available with either standard or precision tolerances. Torrington is a qualified producer of control bearings as specified under MIL-B-7949. Fafnir rod end bearings are sealed unit assemblies with an integral shank for mounting. A spherical outer raceway and either a double row of balls or a single row of spherical rollers permit up to ±10° of misalignment between the inner ring and outer ring (banjo). Shanks can be supplied with internal or external threads, hollow or solid. Torrington is a qualified producer of rod end bearings as specified under MIL-B-6039 and NAS standards.

Wide Inner Ring Ball Bearings and Housed Units
Wide inner ring ball bearings are commonly supplied as inserts in housed units for greater ease of mounting. The inner ring locking device attaches to the shaft, while bolt holes in the housing simplify assembly to machine frames. Self-aligning features further facilitate installation.

Fafnir precision ball screws provide controlled linear motion for accurate positioning and efficient performance in drive axes of machining centers, robotics and similar applications. These advanced units consist of controlled induction-hardened screws with case-hardened nuts and rolling ball elements. Optimized ball track geometry produces enhanced load capacity and running accuracy. Custom-designed for machine tool manufacturers, Fafnir ball screws are offered in the highest precision classes available, from ISO Class 1 to the lower tolerances of ISO class 7. The design simplifies installation with balls circulating internal to the nut without any external tubes or clamps protruding from the surface. Ball screws are available in a variety of lengths, diameters, lead combinations and lubricants. Typical Applications

Angular
Contact Ball Bearings
Typical Applications 
Fafnir airframe ball bearings are produced in two basic designs for
the exacting demands of commercial and military aircraft. They are
specifically designed to meet requirements of extreme temperature,
low torque, high loads, misalignment and low mass. 
Typical Applications 
Designed for ease of mounting, Fafnir wide inner ring ball bearings
carry radial, axial and combination loads. The assembly consists of
a single-row ball bearing with an inner ring that extends on both
sides for maximum shaft support. The extended inner ring slips onto
the shaft and is attached by a self-locking collar or setscrew
locking device. In either style, the bearing can be positioned
easily on the shaft without shoulder, locknuts or adapters. 
Housed units include pillow blocks, flanged cartridges, cylindrical
cartridges and take-up units. The standard housing material is cast
iron. Fafnir TDC® coated bearing inserts with nickel-plated or
polymer SURVIVORTM housings resist
corrosion in difficult operating environments.
