GGB-DB bearings are available in 3 standard bronze alloys:

  • GGB-DB-B: Standard material fulfills most application requirements
  • GGB-DB-C: High load capacity with maximum corrosion resistance
  • GGB-DB-D: Highest load capacity, but less corrosion resistance than GGB-DB-C

with graphite inserts: GGB-DB-B-11 ǀ GGB-DB-C-11 ǀ GGB-DB-D-11

with PTFE inserts:  GGB-DB-B-16 ǀ GGB-DB-C-16 ǀ GGB-DB-D-16

 

Nothing changes except the name of the GGB bearing material: to better fight against counterfeiting, GGB has changed DB into GGB-DB®.
