Replace a Track roller bearing with a Sleeved Bush bearing

[Karthikeyan SR]

Hi.

I have issue of continuous failure of Track roller because of excess loading.
I am looking for bush bearing with bearing pressure with 150 to 200 MPa @ 0.144 m/sec sliding speed & Friction coefficient shall be max 0.1.
I will install a sleeve on the bush bearing & use it as a roller .
Can anyone suggest an appropriate bearing ?

I verified the catalogs of standard bearing manufacturers . The bearing pressure reduces drastically w.r.t sliding speed. The reason may be due to increased heat generation.

Have you considered a heavy-duty linear slide solution from a company like NB, THK, or NSK? All make slides that have high load capacities.

Dear Sir,
Thank you for the info.

I checked the catalogs . The required configurations ( dimensions ) is not available in the standard product range.
I am looking for a replacement of a FARO make bearing 2.2149 with higher capacity (35 to 40 Tons).
