Frequently Asked Questions
Q: What material is the 30A164 bearing assembly constructed from?
A: The 30A164 is a single shield precision ball bearing assembly constructed with SAE 52100 bearing-grade steel. This material is a high-carbon chromium steel that provides superior hardness and wear resistance, making it suitable for repeated loading cycles in manual pallet jack wheel applications across warehouse and industrial environments.
Q: Which manual pallet jack models does the 30A164 bearing assembly fit?
A: The 30A164 is a universal precision ball bearing assembly for manual pallet jacks. It is compatible with most standard manual pallet jack models from manufacturers including Crown, Yale, Raymond, Toyota, and other industrial equipment brands. Verify that your existing bearing dimensions match before ordering to ensure proper fit.
Q: Is the 30A164 bearing assembly pre-lubricated?
A: Yes. The 30A164 comes factory-lubricated and ready to install. The bearing assembly requires no additional lubrication before use. However, periodic maintenance checks are recommended in high-use applications to monitor lubrication condition and bearing wear.
Q: What is the expected service life of the 30A164 bearing assembly?
A: Bearing lifespan depends on load, usage frequency, and environmental conditions. In typical warehouse applications with regular maintenance, SAE 52100 precision bearings perform reliably for 2-5 years. Wet or corrosive environments may reduce this timeframe. Monitor for noise, resistance, or lateral play to detect bearing degradation.
Q: What does the single steel shield protect on the 30A164?
A: The single steel shield on the 30A164 provides protection against dirt, moisture, and debris ingress to one side of the bearing. This configuration balances protection with bearing efficiency. The shield does not create a sealed cavity, so dust and moisture can still accumulate over time in high-contamination environments such as outdoor or cold storage applications.
