SB-09G Material Specifications   SB-09G  cylindrical bushings Metric Sizes    SB-09G   flanged bushings Metric Sizes

SB-09G | CuSn8 wrapped bronze bush, diamond indents filled with GRAPHITES, metric size   SB-09G bushings are similar to the SB-090 range, except there are solid GRAPHITE embedded into the diamond shaped lubrication indents on the bearing surface, which provide good lubrication conditions at the start up stage, even with a lack of oil. It can be used in construction machinery, gear boxes, automotive clutch parts etc.   Bronze alloy + Graphites   Chemical Composition (%)   Type    CuSn8P + Graphites    Cu=91.3%  Sn=8.5%  P=0.2%  Pb=0%  Zn=0%      Lead Free      CuPb10Sn10 + Graphites    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 1. Easy of fitting and lubrication 2. High load capacity 3. Excellent wear resistance with lower friction 4. High level thermal conductivity 5. Minimum overall dimensions 6. Chemical resistance 7. Can work under dry/marginal lubrication for short period, lower friction factor at initial moving Initial pre-lubrication at assembly is required... Typical Applications This type of bushing is widely applied in hoisting machines and other construction machines, automobiles, tractors, trucks, machines tools and some mineral engines.
