P3178

Frequently Asked Questions

Q: What are the dimensions and specifications of the P3178 bearing assembly?
A: The P3178 is a double-shielded ball bearing with the following specifications: 20 mm bore, 47 mm outer diameter, and 14 mm width. It meets ABEC-1 (ISO Normal) precision class standards for material handling equipment. These dimensions match many manual pallet jack load and steer wheel applications.

Q: What material is the P3178 bearing constructed from?
A: The P3178 is manufactured from through-hardened high-carbon chromium steel with a reinforced steel cage. This material combination provides durability, corrosion resistance, and low-friction rolling characteristics required in manual pallet jack load and steer wheel applications.

Q: What applications is the P3178 designed for?
A: The P3178 is engineered for manual pallet jack load and steer wheel applications. The double shields protect the bearing from contamination and moisture in warehouse, outdoor, and light cold storage environments. The bearing provides low-friction rolling performance for smooth load handling.

Q: Are there cross-reference or alternative part numbers for the P3178?
A: No documented cross-reference part numbers are available for the P3178. When ordering, reference the exact SKU (P3178) and confirm bearing dimensions (20 mm bore x 47 mm OD x 14 mm width) match your manual pallet jack specification.

Q: How durable is the P3178 bearing in material handling use?
A: The P3178 is built for reliability in material handling environments. The double shields and through-hardened steel construction resist wear and contamination. Bearing lifespan depends on load capacity, surface conditions, and maintenance. Inspect regularly for grinding sounds, flat spots, or excessive play that indicate replacement is needed.
