GGB LDD Perforated bronze bearings and bushings to increase lubrication intervals

GGB LDD Cylindrical bushes with lip seals

LDD Bronze Plain Bearings with Grease Reservoirs

CHARACTERISTICS

  • Wear resistant, perforated bronze bearing material with integrated seals for lubricated applications
  • Integrated lip seals reduce installation space, protect the bearing from contamination and prolong service life after greasing
  • Suitable for use with all standard greases
  • Optimum performance under relatively high loads and low speeds
