Frequently Asked Questions
Q: What are the key dimensions of the BA 1209 bearing?
A: The BA 1209 is a double row self-aligning ball bearing with a 25 mm bore diameter, 60 mm outer diameter, and 19 mm width. These dimensions must match your shaft and housing for proper fit.
Q: What is the dynamic load rating for the BA 1209 bearing?
A: The BA 1209 has a dynamic load rating of 22,000 N. This rating indicates the maximum combined radial and axial load the bearing can support during continuous operation without premature failure.
Q: What material is the BA 1209 bearing manufactured from?
A: The BA 1209 is manufactured from high carbon chrome steel (SAE 52100). This material provides hardness, wear resistance, and durability required for electric lift truck applications.
Q: What are the cross-reference part numbers for the BA 1209?
A: Cross-reference part numbers include BK1209 and 1209. These are equivalent OEM designations for the same bearing. Verify compatibility before substitution.
Q: How long does a BA 1209 bearing typically last in service?
A: Bearing lifespan depends on load conditions, speed, lubrication, and environmental factors. Regular lubrication per manufacturer schedule extends life. Replace if noise, vibration, or play develops at the bearing location.
Q: Can the BA 1209 handle misalignment in the shaft and housing?
A: The BA 1209 is a self-aligning bearing, meaning it accommodates small angular misalignment between shaft and housing. However, excessive misalignment will reduce bearing life and load capacity.
