The Essential

DURBAL heavy-duty rod ends in stainless steel, with integral self-aligning roller bearing, series K, male thread, according to DIN ISO 12240-4, full complement design
Right hand thread: BRTM_-90-501 and left hand thread: BRTM_-90-502

  • Housing: 17Cr3 forged steel, case hardened bearing race, superfinished, surface galvanized, free of Cr VI
  • Inner ring:100Cr6 ball bearing steel, hardened, superfinished
  • Rolling element: 100Cr6 ball bearing steel, hardened, superfinished
  • Maintenance: low maintenance, lubrication possible, aluminium-complex-soap-grease, approval according to USDA H1
  • Grease nipple in stainless steel: DIN 3405 D1/A (until size 10) / DIN 71 412 H1 (from size 12), further grease nipples.
  • Temperature range: -45°C to +120°C

Special characteristics:

  • For high speeds, wide swivelling angles or rotating movements. In contract to the cage design, the full complement design is suitable for higher loads but with a lower speed threshold.
  • High loads,
  • Mainly all rod end housings are made of forged stainless steel, extremly high loads resistant and surface electropolished which ensures you a very high corrosion resistance.
  • Low maintenance due to long-term lubrication with food-grade approval; the rod ends can be greased subsequently by means of a funnel or conical grease nipple. Further special grease nipples available on request;
  • Covering discs in stainless steel on both sides to prevent the penetration of coarse dirt particles inside the bearing.

Assembly instruction only for heavy-duty rod ends in stainless steel with integral self-aligning roller bearing with male-thread.
DURBAL Premium Line stainless steel heavy-duty rod ends are all hardened to ensure a long life time even under higher loads.
Therefore torques have to be used according to the table**. Moreover, these heavy-duty rod ends should only be used in areas, where no transverse forces act on the thread.

Available as a complete linkage (system) solution or separately hexagonal locking nuts. For shaft diameters from 10 mm to 30 mm.
