Detailed description

Suitable for long-term use under boundary lubrication without maintenance; recommends initial grease, oil hole bearing surface can guarantee the best fat distribution, while refueling process can greatly improve the life of the product; suitable for heavy load at low speed rotary motion and the rocking motion; excellent carrying capacity, low friction coefficient and low wear rate; no water absorption and oil absorption, dimensional stability; after the press-fit bearing can be processed again to get a better tolerances.
