Product description of TIMKEN Bearing 5203K

TIMKEN Bearing 5203K, It belongs to TIMKEN Bearing > Ball Bearing > Angular Contact Ball Bearings > Fafnir Double Row Angular Contact Ball Bearings (5200, 5300, 5400),Timken® Angular Contact Ball Bearings are designed to handle both radial and axial loading, and are specifically engineered for use in high-speed and high precision applications.

Fafnir Double Row Angular Contact Ball Bearings (5200, 5300, 5400),TIMKEN Bearing 5203K, Timken® 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.

Size Range
Single-row: 10 mm – 150 mm (0.3937 in. – 5.9055 in.) bore
Double-row: 12 mm – 150 mm (0.4724 in. – 5.9055 in.) bore

Design Attributes
Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads.
Expanded options include special lubricants, cage materials, preload and coatings for additional corrosion resistance.

Fafnir Double Row Angular Contact Ball Bearings (5200, 5300, 5400)are engineered for use in high-speed, high precision applications for:
Agriculture
Chemical
General industry
Utilities
Fafnir Double Row Angular Contact Ball Bearings (5200, 5300, 5400) TIMKEN Bearing 5203K, consist of two single-row angular contact ball bearings in back-to-back(DB) arrangement with integral double inner and outer rings.Double-row bearings require less axial space than two single-row bearings and can take radial loads as well as axial loads in both directions. The back-to-back arrangement provides a high moment tilting load-handling capability.

Double-row angular contact ball bearings can be open on both sides, or closed by seals (2RS suffix) or shields (ZZ suffix).

Fafnir Double Row Angular Contact Ball Bearings (5200, 5300, 5400) are units with solid inner and outer rings and ball and cage assemblies with poly amide, brass or sheet-steel cages. Their construction is similar to a pair of single-row angular contact ball bearings in an O arrangement, but they are narrower to a certain extent. They differ in the size of the contact angle and the design of the bearing rings.
