PR 11030-6

Frequently Asked Questions

Q: What is the PR 11030-6 bearing and what equipment does it fit?
A: The PR 11030-6 is an OEM ball open bearing designed for manual pallet jack models. It is used in wheel and axle applications on Prime Mover pallet truck equipment. Cross-reference numbers are PM-11030-6-ORG and KO 11030-6.

Q: What does ball open bearing type mean?
A: Ball open refers to an unsealed ball bearing design where balls run directly in races without protective seals or shields. This design allows unrestricted lubrication access but requires regular maintenance and protection from contamination in warehouse environments.

Q: Are PM-11030-6-ORG and KO 11030-6 interchangeable with PR 11030-6?
A: Yes. PM-11030-6-ORG and KO 11030-6 are cross-reference equivalents for the PR 11030-6 bearing. They share the same specifications and mounting dimensions. Verify bore diameter, shaft diameter, and load rating match your manual pallet jack before ordering.

Q: Can PR 11030-6 be used as a replacement for electric lift truck bearings?
A: No. The PR 11030-6 is specified for manual pallet jacks. Electric lift truck load wheel and axle positions require different bearing designs engineered for higher load cycles and speeds. Confirm equipment type and consult the parts manual for correct specifications.

Q: How often should PR 11030-6 ball open bearings be lubricated?
A: Ball open bearings require periodic lubrication based on operating hours and environment. In high-use warehouse settings, monthly or quarterly lubrication is typical. Consult your Prime Mover manual for specific intervals and approved lubricant types.

Q: What are failure symptoms of a worn PR 11030-6 bearing?
A: Worn ball open bearings typically produce grinding or squealing noise during wheel rotation, increased rolling resistance, or visible play or wobble in the wheel. If detected during operation, the bearing should be inspected and replaced if necessary.
