AMI Heavy Duty Mounted Ball Bearings

AMI Bearings meet equipment standards that support infrastructure.

A common issue with industrial fan and HVAC systems is noise. The noise issue comes from shaft vibration caused by improper mounting, tight bearing fit, or excessive loads. This can lead to unexpected and costly downtime for public facilities with ventilation systems. Proper bearing selection is vital to achieve optimal application performance. AMI’s Heavy Duty mounted ball bearings are the ideal choice for most fan applications.

Fan or blower applications tend to operate at higher speeds with a significant amount of radial and axial force. Fan operating conditions can be detrimental on mounted ball bearings, especially if not installed properly on the shaft. Most end users experience installation problems when building or repairing a fan or blower. Heavy duty tapered adapter sleeve expansion and non-expansion mounted bearing units are the solution to this issue. The bearing inserts tapered sleeve, lock nut, and lock washer combination, when secured to the shaft properly, reduce vibration levels by minimizing fan imbalance caused by shaft misalignment.

Key bearing factors to consider with fan applications:

Mounting requirements and current fan setup
Shaft locking mechanism selection
Air handling bearing fit for quieter operation
Shaft speed and load conditions
Operating temperature and environment
