Improper installation causes an estimated 27 percent of all bearing failures, making it one of the leading causes of unplanned downtime and lost productivity for many end users. Many users will over-tighten a bearing, thinking the harder they torque a bearing onto the shaft, the better the performance. Unfortunately this is not the case, as over-tightening a bearing can reduce internal clearances and cause a bearing to overheat during operation and fail prematurely.
Likewise, if a bearing is not securely affixed during installation, the shaft can slip within the bearing, causing excessive wear, vibration and ultimately failure. To avoid setting and adjustment errors when installing a bearing, you can use feeler gauges to judge proper installation based on internal clearances.
Rexnord® recognizes that replacing bearings on equipment should be straightforward and error-free, so it offers patented shaft attachment options to improve shaft holding force and simple installation.
Rexnord SHURLOK® Bearings help solve installation problems with Spyglass™ Optical Strain Sensor technology, which shows the installer when the correct tightness is achieved through a color change, taking the guesswork out of installation. Also, the Rex® 6000 Series SHURLOK Adapter Mount Roller Bearing requires less lubrication and is ideal for ISO 14000 compliance.
