SB-SBSR | SAE841 spherical sintered bronze bearings with ring
It's made of bronze powder, mold pressed in high pressure, sintered in high temperature and soaked
in oil by vacuum. It's used in domestic electric appliances, electric tools, textiles machinery, chemical
machinery and automobile industry, etc.
Why PM ?
The Powder Metallurgy (PM) process provides a host of advantages over cometing metal working
technologies. These all add up to cost-effectiveness, shape and material flesibility, application versatility,
and part-to-part uniformity for improved product quality.
