High-Quality Self-lubricating Bearings Bush with Competitive Price

Straight & Flange Type

Price & Delivery Time on Request. Metric & Inch Size. Stronger. By Oilless Bushing Design.

The bushing, embedded in oil-free solid lubricants, is a new type of strong copper alloy, which is homogeneously embedded with solid lubricant in its body.

Bronze Bushings are made of strong cast bronze based metal with special solid lubricants embedded.

The base metal can withstand high loads and solid lubricants provide self-lubrication. The bushing shows excellent performance without pre-lubrication in extremely high/low temperatures at low speed. This material provides a maintenance-free bushing solution, especially under high loads and intermittent vibrational motion.

Bronze with solid lubricant plugs – Oilless bush according to customer’s request

Solid bronze bushings can be lubricated with either oil or grease.

Oil-Free Flange Bushings, Bronze With Graphite Self Lubricating Bushings are now available online.

Lubrication-Free Bronze Bearing With Graphite Plug Straight & Flanged Type

The bushing which is embedded in the oil-free solid lubricant is made of strong material and is homogeneously embedded in its body with solid lubricant. It breaks the limit of the general bearing, the lubrication of which depends on the oil film. It is, therefore, suitable for high temperatures, high stress, corrosion protection, or when oil is difficult to import. The performance doubles in terms of both hardness and wears friction. It is widely used today in successive casting machines, steel rolls in metallography, mineral machines, ships, steam turbines, hydraulic turbines, and injection molding machines for plastics.
