Supplier KMZ offers circle, wire, pipe brand С93700 at economical price. Regular customers can take advantage of the discount discount. The provider ensures timely delivery of products to any email address. The price is the best in this segment of the rental.

Technical characteristics

Bronze С93700 belongs to the group of tin bronzes with a high lead content. This alloy has excellent mechanical properties, medium strength, good corrosion resistance, and also works satisfactorily in the slightly acidic and saline fluids (e.g. mine water). Has a low coefficient of friction, and can be used in conditions of inadequate lubrication, with a slight misalignment of the contact surfaces. The bronze bearings of this brand is much better working in tandem with a hardened shaft, and allow the maximum shaft speed 4 m/s.

Application

Plain bearings made from alloy C93700 have excellent wear resistance under high speed, heavy pressure and vibration, Bearings operating under conditions of high speed and heavy pressure, the working parts of pumps and turbines (particularly wheels), corrosion-resistant products, the sealed castings.
