Dry Bush


Bearing layer of OMT-106 is composed of excellent designed woven structure of PTFE fiber and high strength synthetic fibers with specially formulated solid lubricant additions.

OMT-106 composite bearings maintain high compressive strength with fiberglass-epoxy backing layer which is manufactured at a specific angle by filament winding process.

OMT-106 is self-lubricating sliding composite bearing with high load carrying capacity to be applied under slow speed rotating, oscillating and reciprocating movements.

OMT-106bearings have excellent wear resistance property and very good resistance against shock, vibration loads.

There are two types of bushes in OMT-106, SF-A and SF-B which difference as per application.
