Frequently Asked Questions
Q: What are the specifications of the TO 14536-11240-71 bearing?
A: The TO 14536-11240-71 is a double-shielded ball bearing with the following specifications: 17 mm bore diameter, 40 mm outer diameter, 12 mm width, and ZZ shield construction (two metal shields). Bore and outer diameter must match your equipment before installation.
Q: What equipment does the TO 14536-11240-71 bearing fit?
A: The TO 14536-11240-71 is designed for electric lift truck applications requiring high-speed bearing performance. Cross-reference to KOYO 6203ZZ confirms this is a standard 6203 series deep groove ball bearing in sealed configuration. Verify bore and outer diameter compatibility with your equipment spindle or motor shaft.
Q: What material is this bearing made from?
A: The TO 14536-11240-71 is manufactured from hardened SAE 52100 bearing steel. SAE 52100 is a high-carbon chromium steel that provides excellent hardness, wear resistance, and fatigue strength required for high-speed industrial applications like electric lift truck motors and pumps.
Q: What is the basic dynamic load rating for this bearing?
A: The TO 14536-11240-71 bearing specifications list a basic dynamic load rating, which indicates the radial load capacity at 1 million revolutions. Verify the complete load rating specification from the bearing data sheet to confirm this bearing supports your application load and speed requirements.
Q: What cross-reference or equivalent part numbers are available?
A: The TO 14536-11240-71 cross-references to KOYO 6203ZZ, 65081-16, and alternative Toyota part number TY14536-11240-71. If this exact SKU is unavailable, these equivalent part numbers provide compatible replacements. Always verify dimensions and load ratings match your application.
Q: How long does this bearing typically last in electric lift truck service?
A: High-speed sealed ball bearings in electric lift trucks typically last 3 to 5 years depending on operating hours, load conditions, and maintenance. Hardened SAE 52100 steel provides extended durability in demanding industrial environments. Replace when noise, excessive play, or heat generation occurs.
