Replace a Track roller bearing with a Sleeved Bush bearing

Click For Summary
SUMMARY

The discussion focuses on replacing a failing Track roller bearing with a Sleeved Bush bearing due to excessive loading. The user requires a bush bearing capable of withstanding bearing pressures between 150 to 200 MPa at a sliding speed of 0.144 m/sec, with a maximum friction coefficient of 0.1. Recommendations include considering heavy-duty linear slide solutions from manufacturers such as NB, THK, and NSK, which offer high load capacities. The user specifically seeks a replacement for a FARO make bearing 2.2149 that can support 35 to 40 tons.

PREREQUISITES
  • Understanding of bearing pressure and friction coefficients
  • Familiarity with sliding speed and its impact on bearing performance
  • Knowledge of heavy-duty linear slide solutions
  • Experience with catalog verification for bearing specifications
NEXT STEPS
  • Research heavy-duty linear slide solutions from NB, THK, and NSK
  • Investigate custom bearing options from FARO or similar manufacturers
  • Explore advanced materials for bush bearings that can handle high loads
  • Learn about the thermal effects on bearing performance at varying sliding speeds
USEFUL FOR

Mechanical engineers, maintenance professionals, and anyone involved in the design or replacement of high-load bearing systems.

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.

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).
