Frequently Asked Questions
Q: What are the dimensions of SKU 3018590?
A: The 3018590 tapered roller bearing seal has an inner bore diameter of 41.275 mm, outer diameter of 73.025 mm, and width of 16.667 mm. These dimensions are critical for proper fitment in pump assemblies. Verify dimensions against your original bearing before ordering.
Q: What are the load ratings for bearing 3018590?
A: The 3018590 is rated for 51 kN dynamic load and 55.5 kN static load. These ratings apply to continuous duty operation. Exceeding load ratings reduces bearing life and causes premature failure. Confirm your pump application load requirements match these ratings.
Q: What cross-reference part numbers match 3018590?
A: SKU 3018590 cross-references to bearing designations 18590 and 18520. OEM equivalents include Timken 18590-90010, NTN 4T-18590/18520, and Koyo 18590/20. All cross-references have identical dimensions and load ratings. Confirm OEM part number against your equipment specification before ordering.
Q: What cage material is used in 3018590?
A: The 3018590 bearing features a pressed steel cage. Steel cages provide durability and stability under high-speed industrial duty. The cage construction is compatible with synthetic lubricants and extended oil change intervals common in electric lift truck pump systems.
Q: What is the operating temperature range for bearing 3018590?
A: The 3018590 bearing operates from -40 degrees Celsius to 120 degrees Celsius. This range covers cold storage facilities and heated warehouse environments. Verify your pump ambient temperature stays within this range. Extended exposure to temperatures outside this range reduces bearing life and lubricant performance.
Q: Which electric lift truck pump assemblies use 3018590?
A: The 3018590 bearing is used in pump assemblies for Crown, Toyota, Raymond, and Jungheinrich electric lift trucks. Cross-reference your pump OEM part number with our bearing catalog. Contact us with your truck model and pump identification to confirm the correct bearing is ordered.
