More Information


SINTF Flanged Bushing

Operating temperature range from -12°C to +100°C (exceeding these temperatures may require additional lubrication).

Oil loss and additional lubrication:

Contact between the bushing and absorbent materials should be avoided to prevent oil loss. The bushings should be stored in plastic packaging. Additional lubrication is usually not necessary, but may be helpful under difficult operating conditions. This can be achieved by immersing the bushing in oil heated to 80°C and leaving it there until the oil cools down.

What shafts are the bushings designed for?

It is recommended to use the bushings with hardened shafts or shafts with a well-finished surface. When using stainless steel, it is recommended that the shaft surface be polished or chrome-plated to overcome the abrasive effect of the material. Shaft tolerance: h6 - h9 depending on the E7 bushing tolerance.

Further machining of the bushing:

Any additional machining of the sintered bronze bushing should be carried out using carbide (K20 / 01) or a diamond-tipped tool. Cutting speed: 100 - 150 m/min. The working surface should not be ground or cut, as this will clog the pores of the material, which are essential for the lubrication effect.

In the case of very high loads, temperatures or speeds, lubrication may be necessary.
