In. Anti-Friction Side Bearing for Tenders. the case of the tender roller bearing, there are five rollers 4 diameter and 3 in. long, which are equivalent to one largeroller 10 in. in diameter and 6 in. long. These rollers have aside clearance of ]/s in., and the friction is restricted to therolling on the two bearing plates. The drawing shows a three roller bearing for freiglit cars. These rollers are corrugated, which allows them to be in contactin all positions and still have a greater length of travel thanin the case of the flat-sided roller. In the normal position thecorrugations will be in contact at their apices. .\s the rollersmove to one side or the other the apex of one corrugation willslide into the hollow of the other until there is a positive bearing,as shown in the illustration. Of course, it is necessary that thesecorrugations be carefully made to the correct radius, which isone-half the width of the roller. In this case, the travel is l!/>in. on each side of the ce
