SB-090 | CuSn8 wrapped bronze bush, diamond oil pockets, ISO3547 standard   SB-090 series bearings are wrapped from a cold formed homogenous bronze CuSn8 (alternative CuPb10Sn10) with exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents in the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications.   Bronze alloy   Chemical Composition (%)   Type    CuSn8P    Cu=91.3%  Sn=8.5%  P=0.2%  Pb=0%  Zn=0%    Lead Free    CuPb10Sn10    Cu=Balance. Sn= 9~11%, Pb=9~11%    With Lead    * Available bronze alloys used in this part:  BS 2874 PB104 / BS EN 12163 CW453K / NFL 14703 / ISO 427 DTD 265A / QQ B 750 D / SAE J 461 CA521 / ASTM B 139 C52100 / ASTM B 103 C52100 / SAE J463 / DIN 17672 2.1030 / JIS H 3741 / SIS 14 54 31  Features Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the transfer film created will protect the mating metal surface. Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling. Also performs well with lubrication. Typical Applications     This type of bushing is widely applied in Agricultural machine, construction machine, crane, underpan parts, conveyor, elevator, winch, planing machine... It can be fabricated into bushes, half bearings, flanged bushes, trust washers, spherical bearing and so on...
