Frequently Asked Questions
Q: What are the exact dimensions of the 8505-2RS precision bearing?
A: The 8505-2RS has an outer diameter of 2.047 inches (52 mm), inner diameter of 0.984 inches (25 mm), and width of 0.669 inches (17 mm). These dimensions match BS 8505 2RS specification. Verify these measurements against your equipment before ordering.
Q: What material is the 8505-2RS bearing made from?
A: The outer and inner rings are manufactured from through-hardened bearing steel equivalent to SAE 52100, and the balls are bearing-grade chromium steel. This construction provides high load capacity and extended service life typical of manual pallet jack applications.
Q: What does the double rubber seal on the 8505-2RS do?
A: The double rubber seals (2RS designation) keep contaminants, moisture, and dust away from the rolling elements and grease inside the bearing. This protection is especially important in warehouse and outdoor environments where the bearing is exposed to floor debris.
Q: Is the 8505-2RS pre-lubricated?
A: Yes, the bearing is factory lubricated and sealed. Low-maintenance operation is one of the key benefits. The sealed rubber shields protect the lubrication and reduce the need for re-greasing during normal use.
Q: Which manual pallet jack brands use the 8505-2RS bearing?
A: The 8505-2RS is a cross-brand precision bearing used in manual pallet jacks and load wheels from Crown, Toyota, Raymond, Yale, and other manufacturers. Confirm the bearing size matches your equipment before ordering.
