Frequently Asked Questions
Q: What equipment does the 3051170 double-sealed bearing fit?
A: Part 3051170 is a double-sealed bearing assembly designed for manual pallet jack load and steer wheels from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, and BT equipment. The bearing has a 20 mm bore, 47 mm outer diameter, and 14 mm width. Verify your wheel hub dimensions match these specifications before ordering to ensure proper press-fit installation.
Q: What material is the 3051170 bearing made from?
A: The 3051170 bearing assembly is constructed from hardened SAE 52100 bearing steel with precision chromed steel balls. SAE 52100 is a high-carbon alloy steel that provides superior hardness, fatigue resistance, and wear characteristics essential for heavy-duty material handling applications. The precision chromed balls ensure smooth rotation and long service life under continuous load.
Q: Why does 3051170 have double seals, and what is the advantage?
A: Double seals on the 3051170 bearing provide contaminant exclusion on both sides of the bearing, blocking dirt, moisture, and floor debris from entering the bearing. This is especially critical for pallet jacks used in cold storage, wet floors, or dirty warehouse environments. Double-sealed bearings require less frequent maintenance cleaning compared to single-shield bearings and typically last longer under harsh conditions.
Q: What is the bore and outer diameter of part 3051170?
A: Part 3051170 has a 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. These dimensions are critical for proper press-fit mounting into your wheel hub. Do not attempt to install this bearing if your wheel hub bore is not 20 mm. Undersized or oversized bores will result in improper seating, wheel misalignment, and potential bearing failure or safety hazards.
Q: How long does the 3051170 bearing typically last in cold storage applications?
A: In cold storage operations where moisture and temperature fluctuations are common, the double-sealed 3051170 bearing typically lasts 3 to 5 years with regular maintenance. The seals are designed to exclude ice and moisture, extending service life compared to single-shield bearings which would require frequent cleaning in these conditions. Lifespan depends on equipment utilization, maintenance frequency, and overall load intensity.
