STAMPED STEEL IDLER SHEAVE BEARING BORE ADAPTER INSTALLATION INSTRUCTIONS
•
•
Disconnect and lock-out power before installation and maintenance. Working on or near energized equipment can result in severe injury or death.
•
Do not operate equipment without guards in place. Exposed equipment can result in severe injury or death.
•
Read and follow all instructions carefully.
The sheave bearing has an inside diameter (bore) of 17 mm. However, three types of bearing bore adapters are available to allow this sheave to operate on either a 3/8” or 1/2” diameter shaft. These adapters are available as either a Sleeve type or two different shoulder types. When installing a bore adapter into the bearing of the idler sheave, it is recommended that a rigid device capable of providing even and steady force, such as an arbor or hydraulic press be used to reduce the chances of damaging the bearing. Damage to either the inner or outer bearing race, or the bearing seal, could lead to premature bearing failure. Depending on the style of adaptor being installed and referencing Figures 1 through 3, at right, bore adapters are installed as follows: 1. Rigidly support the inner bearing race on the opposite side from which the adapter is to be installed. Care must be taken to not disturb the bearing seal with the supporting structure. 2. Place the bore adapter squarely on the bearing face while aligning the adaptor with the bearing bore. 3. Bring the press head down until it contacts the face of the adapter and press the adapter into the bearing bore. No more than 300 lbs. of force should be required to seat the adapter into the bearing bore. 4. Visually ensure the adapter has properly seated into and/or up against the bearing inner race. 5. Ensure the sheave spins freely about the inner bearing race with no clicking or tight spots indicating possible bearing damage.
