Product description of TIMKEN Bearing 7308 BJ

TIMKEN Bearing 7308 BJ, It belongs toTIMKEN Bearing > Ball Bearing > Angular Contact Ball Bearings > Timken® Single Row Angular Contact Ball Bearings (7200, 7300). and related type you may also like TIMKEN Bearing 7308 BM/CN Timken single row angular contact ball bearings can accommodate axial loads in one direction only. This type of bearing is typically adjusted against a second bearing. Their bearing rings have an upper and a lower shoulder and are non-separable.Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis

TIMKEN Bearing 7308 BJ, Single row angular contact ball bearings are particularly suitable where:
bearing arrangements must support combined loads
moderate to high axial loads are present on one side
rigid axial guidance is required
the bearing arrangement must be axially clearance-free or preload-ed
high speeds are required under higher radial and axial loads.
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 7308 BJ,Timken® Single Row Angular Contact Ball Bearings (7200, 7300), 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 7308 BJ,Timken® Single Row Angular Contact Ball Bearings (7200, 7300)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.
