Can two bolts at both sides be used instead of an axle in a roller drum? The current setup has two ball bearings mounted on a stepped axle on both the sides of the drum. Will the two bolts setup damage the bolts or the drum? Is there a reason why an axle is used instead of bolts? Only reason I can think of is to ease removal of the bearings using the stepped part of the axle. If somebody can provide a explanation with a diagram of pressure points etc that be great. You can email me at khurdp at yahoo.
*An axle bolt has a shaft with a pair of opposed ends. An axle passage extends within the shaft and a transverse passage extends radially outwardly from the axial passage. A head attached to one end of the shaft has an outer face. A recess extends in from the outer face and the bottom of the recess is in communication with the axial passage. A lubrication fitting in the recess has one end in communication with the bottom of the recess and another end designed to be connected to a lubrication device. The recess in the bolt head is sufficiently deep that the second end of the lubrication fitting is within the recess and does not extend beyond the outer face.
