MI 800806205

Frequently Asked Questions

Q: What are the specifications of the MI 800806205 bearing?
A: The MI 800806205 is a deep groove ball bearing with a 25 mm bore, manufactured from high-carbon chrome bearing steel equivalent to SAE 52100. It features HRC 60-64 Rockwell C hardness, a single metal shield, and pre-lubricated, maintenance-free design.

Q: Where does the MI 800806205 bearing fit in manual pallet jacks?
A: This bearing is designed for manual pallet jack load wheel and pivot applications. It accommodates a 25 mm bore shaft. Verify your pallet jack model to confirm bore diameter before ordering to ensure proper fit and operation.

Q: Why is high-carbon chrome bearing steel used in the MI 800806205?
A: High-carbon chrome bearing steel (SAE 52100 equivalent) provides superior hardness and wear resistance under repeated loading and rolling stress. The HRC 60-64 hardness rating ensures the bearing resists deformation and maintains dimensional stability in demanding material handling environments.

Q: Is the MI 800806205 maintenance-free?
A: Yes. The MI 800806205 comes pre-lubricated and is designed as maintenance-free. The single metal shield protects internal races from contamination while allowing the bearing to operate sealed. Do not attempt to relubricate or service this bearing.

Q: What is the expected lifespan of the MI 800806205?
A: Bearing lifespan depends on load, frequency of use, and operating conditions. In typical manual pallet jack service, a properly installed MI 800806205 will perform reliably for several years. Replace if you notice increased friction, grinding noise, or lateral play in the wheel or pivot.
