Wear-resistant special additive dispersed sintered bronze bearings with back metals
We believe that by being creative and constantly striving to challenge ourselves we provide the highest-quality bimetal bearingfrom china.
The bimetal bushing is steel backed with high-quality with tin-
- Con Rod Bearing Bush
- Sleeve Bush for Rocker Arm
- Cam Shaft Bearing Bush
Bimetal bearing bushes have high-performance environmentally friendly dual metal bearings that are customer-specified products. bimetal bearing bushes use low-carbon steel plate as supporting base and powder metallurgy sintering and rolling processes to form a leadless CuSn8Ni steel-copper alloy product. The materials in this product meet RoHS directory/regulation/rule, under certain circumstances can substitute for JF800 products. bimetal bearing bushes have a high load-bearing capacity and good wear-resistance. Its shortcoming is that it cannot be used without oil lubrication. In places where oil lubrication is sufficient, bimetal bearing bushes have superior performance.
Our sales assistant team will provide bronze bushings service for each of your needs.
Once we receive your request, we will contact you, and the sliding bushings qualified type will be recommended to you within 24 hours.
The designing of oil indentations | ||||||
In order to fully lubricate the bush when in the performance, the indentations with size as following are recommended. They should be manufactured according to the standard below if without special requirements. | ||||||
Bush O.D | More than 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 the butt joint and loading area and designed to be easy-oil-feeding as well. |
