Product description of TIMKEN Bearing 7218WN SU

TIMKEN Bearing 7218WN SU, It belongs to TIMKEN Bearing > Ball Bearing > Angular Contact Ball Bearings > Fafnir® Single Row Angular Contact Ball Bearings (7200, 7300, 7400).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.

TIMKEN Bearing 7218WN SU,Fafnir® Single Row Angular Contact Ball Bearings (7200, 7300, 7400), 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.

TIMKEN Bearing 7218WN SU,Fafnir® Single Row Angular Contact Ball Bearings (7200, 7300, 7400)are engineered for use in high-speed, high precision applications for:
Agriculture
Chemical
General industry
Utilities

Single-row angular contact ball bearings are designed to handle radial and axial loads simultaneously. However, they can only accommodate axial loads in one direction. As a result, most single-row angular contact ball bearings are mounted in pairs.Single-row angular contact ball bearings are available in either standard or universally matched designs.

In angular contact ball bearing design, the forces are transmitted from one raceway to the other along a given contact angle. This angle is defined as the angle between the line of action of forces and a radial plane (Fig. 3). The result is a larger contact angle increasing the bearing's axial load capability.

TIMKEN Bearing 7218WN SU,Fafnir® Single Row Angular Contact Ball Bearings (7200, 7300, 7400) CONTACT ANGLE The contact angle of an angular contact ball bearing is the angle between a line through the ball center perpendicular to the bearing axis and a line through the two points where the ball contacts the races when the bearing axial play is removed. Timken single-row angular contact ball bearings of series 7200and 7300 have a contact angle of 40 degrees and Timken double-row angular contact ball bearings of series 3200 and 3300 have a contact angle of 30 degrees which allow them to accommodate high axial loads.
