Alternator

Uses a tolerance ring to mount a bearing in the cast housing, this excellent mounting solution competes against alternative technologies of plastic / rubber boots and glue


Benefits include:

• Mounting bearings – improves NVH properties
• Reduces bearing temperature by up to 6 degrees
• Easy to assemble
• Allows rework
• Use of as cast housing
• Glue can have a tendency to give off gases during

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
