Special Bearing 6905-2RS For Automotive Steering Systems

Automotive Steering System Specific Bearing 6905 Standard Grade CM HG03 Grease (-40~180℃)

Automotive steering systems typically use seven bearings. The main requirements for these bearings are:
① High precision and smooth rotation
② Resistance to axial impact and no abnormal movement
③ Long service life, meeting automotive warranty standards
BLH bearings, designed and manufactured specifically for steering systems to meet these requirements, have been widely used in steering systems of internationally and domestically renowned automotive brands.

Despite the increasing use of electrical controls in automobiles, many internal systems are still designed along traditional lines.
For example, the steering column connects the steering wheel at the upper end and the steering gear (rack and pinion) at the lower end.
The steering column generally consists of a column fixed to the vehicle body, a steering shaft 6905ZZ, and a drive shaft. The steering shaft is typically supported by two bearings at the top and bottom of the column.
Steering Column Bearings
We have developed a range of such bearings specifically for this application, known as upper and lower bearings. These include 6905-2RS deep groove ball bearings (DGBB),
preloaded coil steering column bearings (PWSCB), and robust angular steering column bearings (ASCB). They offer numerous advantages.

Low torque, low noise
No machining required for shaft and bearing housing
Stable angular steering column bearing
Patented rubber shock absorber reduces vibration
Reduced torque variation
Excellent vibration damping
No axial and radial play (preloaded bearings)
Optimal balance between stiffness and friction torque
Axial load component of 10kN

This 6905ZZ steering bearing is also known as a steering wheel bearing, upper steering column bearing, and lower steering column bearing.
The terminology for steering bearings varies in different countries. The following are some of the names frequently used by our international customers when inquiring about these bearings:
steering column bearing, knuckle bearing, steering shaft bearing, bearing steering, head bearing, neck bearing
Due to the variations in terminology, it's best to provide drawings or pictures when making inquiries so that we can respond more quickly.
