Re: Solid Bearings vs. Roller Bearings

Dave, all those Kawasaki KZ 900/1000/1100's & Suzuki GS 1000/1100/1150's all used roller bearing cranks and rods. The Japanese started phasing them out in the late 80's. None of the new bikes today

Bob, you may have seen the same in a Railway Age article from the 1940 time span. It strikes a familiar note with me also. I cannot be certain however that is only 10 years and twenty large books to

Solid Bearings vs. Roller Bearings

The industry had long time experience with roller bearings applied to passenger cars, both heavy weight and light weight and steam locomotives. Great Northern, a paragon of thrift, started installing

Re: Solid Bearings vs. Roller Bearings

Todd, "Solid bearings have less drag than roller bearings at speed." Not true for freight cars. I can't comment on the HP difference for motorcycle engines, but the cost of a RB equipped motorcycle

Re: Solid Bearings vs. Roller Bearings

Very close. but there is a wedge above the brass/babbate bearing that needs to be removed before the bearing can be removed. Howard (son of a...carman) Garner

Re: Solid Bearings vs. Roller Bearings

Bob, What is the date of that volume? Specific to the "over-35" claim - the early roller bearings were also oil filled - an appeasement to the old concept that oil immersion in bearings was critically

Re: Solid Bearings vs. Roller Bearings

Solid bearings have less drag than roller bearings at speed. The initial start up from a dead stop might favor roller bearings but the mechanical drag of metal against metal in a roller bearing

Re: Solid Bearings vs. Roller Bearings

Bob, This doesn't answer your question, but many railroads recognized the advantages of roller bearings on freight cars at least by the end of WWII. I have read that railroad

Re: Solid Bearings vs. Roller Bearings

Another important advantage to roller bearings is the markedly reduced initial resistance, meaning that roller bearings start rolling with much less effort than solid bearings. Up here in North

Re: Solid Bearings vs. Roller Bearings

Roller bearings don't get hot boxes; solid bearings do. Roller bearings can fail, but I believe that happened much less frequently than hot boxes with solid bearings. Maintenance is easier because

Re: Solid Bearings vs. Roller Bearings

Reduced maintenance for sure. Roller bearings have gotten so reliable that they are essentially maintenance free for the life of the wheelsets, and are all (wheels, axles; and bearings) changed at

Re: Solid Bearings vs. Roller Bearings

Overall reliability? Rolling resistance below 35mph? Not included in my understanding of mechanical considerations, but certainly a heavy consideration would be maintenance. Thanks! -- Brian
