Show ROLLER BEARINGS ON SWEDISH TRAINS STOCKHOLM, Nov. 11. The me in Sweden of roller bearings for the I wheels of railroad Cars, passenger fund j freight, has le en Inaugurated by the j Issuance of definite orders to the state railways. What promises to be a boon to railroads and travelers the world over, nnd the possible development of a manufacturing industry of larcre proportions is foreseen Tho system of roller bearings as now perfected Is the result of years of experiment and research In Sweden and elsewhere. Th solution of the problem has been hastened because of the Krowlni: need of finding some way to reduce the expense of railroad rail-road operation. A saving of about 15 per cent In coal, together with a reduction of personnel and a conservation conser-vation of equipment, will become feasible fea-sible by the Installation of roller bearings. Travelers will benefit bo-causo bo-causo the elimination of friction means more smoothnevs and less noise In the running of trains. It Is thought also that passenger and freight rates may be lowered as a result of tho new economy In operation- The new bearings are barrel shaped and roll fre.-ly between th.- shaft and the runway, thus being a cross between be-tween ball bearings and the old fash-J loned roller bearings. The Swedish company which manufactures these ' bearings reports that the Pennsylvania Pennsylva-nia railroad has been making experiments ex-periments for some time with a view to their adoption. |
