Frequently Asked Questions
Q: What are the dimensions and load ratings for the HY 3051165 bearing?
A: The HY 3051165 is a precision deep-groove ball bearing with an inner diameter of 35 mm, outer diameter of 72 mm, and width of 17 mm. It has a dynamic load rating of 36.0 kN and a static load rating of 20.0 kN, making it suitable for moderate to heavy radial and axial loads in electric lift truck applications.
Q: What material is the HY 3051165 bearing constructed from?
A: The HY 3051165 features a through-hardened chromium steel (SAE 52100) bearing body with a steel cage. This material composition provides high hardness, fatigue resistance, and durability in critical rotational assemblies typical of electric lift truck drivetrains and load-handling systems.
Q: Is the HY 3051165 bearing pre-lubricated?
A: No, the HY 3051165 is supplied unlubricated. This design is typical for critical rotational assemblies where lubrication must be controlled during installation or where the bearing will operate in a sealed or pre-lubricated assembly.
Q: Which Hyster electric lift truck models use the HY 3051165 bearing?
A: The HY 3051165 is an OEM part compatible with various Hyster electric lift truck models. Verify that your equipments bearing bore matches the 35 mm inner diameter specification before ordering, as bearing compatibility depends on exact equipment model and serial range.
Q: How long does the HY 3051165 bearing typically last in service?
A: Bearing lifespan depends on load application, speed, lubrication practice, and operating environment. SAE 52100 chromium steel bearings in electric lift truck service typically provide 2000 to 5000 operating hours before wear becomes measurable. Premature failure symptoms include increased friction noise, heat generation, or vibration during load cycles.
Q: What is the OEM part number for cross-reference?
A: The OEM part number is Hyster 3051165. Ensure you are ordering the exact unlubricated variant, as lubricated versions may not perform correctly in sealed or pre-lubricated assemblies on your equipment.
