Abstract
PURPOSE: To increase the life of a bearing and to prevent displaced centering of a spacer by forming oil reservoir portion at the spacer and providing positioning portion for radially positioning the spacer to thereby increase the reserved grease amount.
CONSTITUTION: In a rotary roller 1 of thermally molded syntheric resin material upon internal disposition of its boss 11 in the state that bearings 3, 3 aligned via spacers 5, 7 in parallel are engaged with a shaft 9, there is provided positioning portion 17 projected within the annular mumber 19 of the spacer 5 for the internal end of the portion 17 to make contact with the outer periphery of the spacer 7 to thereby position the spacer 5 in radial direction. In addition, oil reservoir portion 21 is formed at the spacer 5 to reserve grease therein. An oil seal 23 is engaged with the portion 21, and grease is charged via a grease nipple 27 into the spaces of the bearings 3, 3 and the oil reservoir portion 21 for the reservation thereof.
