FAQ:
Q: What are the advantages of miniature ball bearings?
A: Miniature ball bearings can be open or shielded, which helps prevent dirt from entering and lubricant from leaking out, and unflanged or flanged for easier plate mounting. Some miniature ball bearing options feature extended inner rings to help fit certain locking devices when a press fit is not possible.
Q: What kind of bearings are the thinnest?
A: Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together.
Q: What kind of bearings are stainless steel bearings?
A: Bearings are 440C stainless steel. These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.
Q: What kind of bearings are used in mining?
A: The addition of iron and aluminum gives these aluminum-bronze bearings high strength and excellent corrosion resistance— making them suitable for use in marine and mining applications. These leaded bronze bearings are strong, wear resistant, and excellent at handling shock loads.
