GGB LD wear resistant bronze bushings with grease reservoirs

GGB LD Cylindrical bushes

LD Bronze Bearings made of CuSn8 with Grease Reservoirs

CHARACTERISTICS

  • Wear resistant bearing made of solid bronze strip with perforation for lubricated applications
  • Improved performance compared with MBZ-B09: larger grease reservoirs increase maintenance intervals, dirt and debris swept into perforations, thereby reducing wear
  • Optimum performance under relatively high loads and low speeds
