Frequently Asked Questions
Q: What are the dimensions of the 65081-20 bearing assembly?
A: The 65081-20 is a single shield ball bearing assembly with an outside diameter of 3.149 inches (80 mm), inside diameter of 1.378 inches (35 mm), and width of 0.822 inches (20.9 mm). These dimensions are critical for proper fitment in Crown PTH50 manual pallet jacks.
Q: Is the 65081-20 compatible with Crown PTH50 pallet jacks?
A: Yes, the 65081-20 is designed as an OEM replacement bearing assembly specifically for Crown PTH50 manual pallet jacks. It replaces Crown Equipment part numbers 65081-020, 065081-085, and CR 65081-020. Always verify your equipment serial number matches the product specifications before purchasing.
Q: What construction materials are used in the 65081-20?
A: The 65081-20 features high carbon steel construction with a deep groove bearing architecture. The single shield design provides radial load support while allowing access for maintenance and inspection. This construction is suitable for typical warehouse and light industrial load applications.
Q: What cross-reference part numbers are equivalent to 65081-20?
A: The 65081-20 has several equivalent part numbers including 65081-020, 065081-085, and CR 65081-020. All these numbers reference the same bearing assembly. When ordering replacement parts, use any of these numbers to ensure compatibility with Crown PTH50 equipment.
Q: How do I know when the 65081-20 bearing needs replacement?
A: Replace the 65081-20 if you experience grinding or squealing noises during equipment operation, increased resistance when moving the pallet jack, or detectable play or wobbling in the bearing. A worn bearing does not perform reliably under load and may cause secondary damage to mast or lift components.
Q: What is the typical service life of the 65081-20 bearing assembly?
A: Under normal warehouse operating conditions with regular use cycles, the 65081-20 typically provides 3 to 5 years of service life. Service life varies based on load intensity, frequency of use, ambient temperature, and maintenance practices. Indoor climate-controlled environments generally extend bearing life compared to outdoor or cold storage use.
