WMB® Bronze Bearing Specifications
The WMB ranges are made entirely of CuSn8. The working surface is rolled with diamond indentations or stamped with oil grooves. On assembly or during operation the indentations can be filled with grease or oil which acts as a reservoir creating excellent long term lubrication.
The bronze bearings are produced from phosphor bronze alloy rolled strip which is hard and has an excellent finish. The material composition is as follows:
Cu – Balance
Sn – 8.5%
P – 0.2%
The WMB range is another extremely versatile range. Please feel free to get in touch with us to discuss your specific project requirements. The bronze bearings can be offered with pockets, grooves or thru-holes for heavier applications.
