Steering Column Bearing Mount

Uses a tolerance ring to mount a bearing to the column whilst adjusting the NVH properties of the column


Benefits include:

• Good performance over a range of component tolerances and operating temperatures
• Performance will not deteriorate with age.
• Improved NVH properties than fits with rubber mounts
• Allows use of non precision components

Tolerance Rings are radial spring fasteners
that are press fitted between two mating components. This generates a retention force that fixes those components together, whilst also satisfying other functional requirements such as Torque Drive, Overload Protection, NVH Performance and Differential Thermal Expansion.


Fasten annular components
Reduce noise & vibration
Compensating for thermal expansion
Predictable & repeatable slip
Avoid resonance frequencies
Overload protection
