SF-80 弥散型自润滑轴承 Point-lubricating bearings
应用特点：以金属为基体表面烧结合含有固体润滑剂的铜合金粉，由于润滑剂弥散于工作表面因此润滑性更为充分。适用于高载低速而无法加油或无法形成润滑膜的场合，并具有较好的耐酸、耐碱性。产品被广泛用于水轮机、注塑机、汽车轮胎模具等。
Application characteristics：Metal backed bronze
with graphite lined bearing materials, sintered
layers are of special copper alloy containing uniformly
dispersed solid lubricants. Suitable for hostile
environments, for high load application which lubricants.
Suitable for hostile environments, for high load
application which lubrication, is difficult. Used
in water turbines, injection molding machinery,
packing machines, construction equipment, tire moulds
etc.
