Mounted Bearing Units

Rainbow Precision Products offers cast iron mounted bearings that adhere to ABEC-1 tolerance standards. These bearings feature a deep-grooved ball bearing insert and are double sealed. The mounted ball bearing units are designed with two set screws positioned 90° apart, ensuring a secure lockdown on the shaft and preventing the inner ring from rotating independently. They come equipped with a steel retainer and a grease fitting for convenient lubrication. The units can accommodate up to 2° of shaft misalignment and operate within a temperature range of –4° to +220°F. Each unit includes a bearing locking collar and set screws.
