Frequently Asked Questions
Q: What are the dimensions of the BS 87506 precision ball bearing?
A: The BS 87506 has an outer diameter of 2.441 inches (62MM), inner diameter of 30MM, and width of 0.551 inches (20MM). These extended inner ring design dimensions make it suitable for specific pallet jack load wheel and drive systems. Verify these measurements match your equipment bore and mounting space before ordering.
Q: What pallet jack brands is the BS 87506 compatible with?
A: The BS 87506 precision ball bearing with extended inner rings fits multiple manual and electric pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich. The extended inner ring design is commonly used in load wheel assemblies. Confirm your equipment model and serial number to verify compatibility.
Q: Why does the BS 87506 have extended inner rings?
A: Extended inner rings distribute load over a larger surface area within the bearing, reducing contact stress and improving load capacity. This design is used in pallet jack load wheels that handle sustained heavy loads. The extended rings help prevent premature bearing failure under continuous-use conditions.
Q: What is the typical lifespan of the BS 87506 bearing?
A: Under normal warehouse conditions (8-10 hour shifts, typical loads), a BS 87506 bearing should last 3-5 years. Lifespan depends on load consistency, environmental conditions (moisture, temperature), maintenance, and equipment alignment. Heavy-duty or continuous-operation environments may require replacement every 2-3 years.
Q: How do I diagnose a failing BS 87506 bearing?
A: Listen for grinding, squeaking, or rumbling from the load wheel area. Spin the wheel freely and feel for vibration or resistance. Check for lateral play in the wheel assembly. Excessive noise, heat around the bearing, or rough operation are signs of internal wear or contamination. Replace if any of these symptoms occur.
