Product Description:
Info:
Tpees for BIM bush's grovves indentations
Lock types of BIM wrapped bushes
The designing of oil indentations
In order to fully lubricate the bush when in the performance,the indentations with size as flows are recommended.They should be manufactured according to the standard below if withoutspecial requirements.
Bush O.D From to 14~22 22!44 40~50 50~100 100~180
Lubricating Hole 3 3 3 6 7
The lubricating hole should be away from butt joint and loading area and designed to by easy-oil feeding as well.
