LubeSite Springs

Selecting the Proper Unit Size and Spring

To determine the LubeSite unit size, you need to know the bearing shaft diameter and speed, as well as the bearing class. For example, if the shaft diameter is 2”, the bearing is sealed and the shaft speed is a continuous 2000 rpm, you will need an extra large unit. See the Size Selection Guide below.

To determine the proper spring, you need to know the operating temperature and the grease weight. For example, if the operating temperature of the bearing ranges from 60ºF to 80ºF, and you’re using grade 2 grease, then you will need a medium (silver) spring. See the Spring Selection Guide on below. If mounting on an extension, use of an extra heavy (orange) spring may be required (spring effectiveness will vary with application).
