Frequently Asked Questions
Q: What are the exact dimensions of mast guide roller bearing 4916533?
A: Bearing 4916533 features an outer diameter of 101.04 mm, inner diameter of 34.79 mm, and width of 28.45 mm. These dimensions are critical for proper mast alignment in electric lift truck applications, so verify compatibility with your equipment specifications before ordering.
Q: What electric lift truck models is bearing 4916533 compatible with?
A: Bearing 4916533 is the OEM mast guide roller bearing designed for Kalmar AC electric lift trucks and comparable equipment from Crown, Toyota, and Raymond. Confirm the mast diameter and bearing pocket depth match your specific model year and series before ordering.
Q: What material composition does bearing 4916533 use?
A: Bearing 4916533 is manufactured from hardened bearing steel raceways with hardened and ground steel components and a steel cage. This hardened construction resists wear and lateral loading typical of electric mast applications where side loads are continuous.
Q: How often should mast guide roller bearing 4916533 be replaced?
A: Bearing 4916533 typically requires replacement every 4 to 6 years depending on daily duty cycles and mast speed. High-cycle operations or equipment operating at maximum lift heights multiple times per shift may require more frequent replacement. Inspect annually for wear.
Q: Will bearing 4916533 perform differently in cold storage versus standard warehouse conditions?
A: Bearing 4916533 operates in both standard warehouse and cold storage environments. Cold storage may slightly increase bearing stiffness at startup, but hardened steel construction resists the thermal cycling stress. Monitor bearing clearances in extreme cold environments where condensation risk exists.
Q: What symptoms indicate bearing 4916533 is failing?
A: Replace bearing 4916533 if you observe mast wobble or lateral movement, squeaking or grinding noise during lift operations, increased mast tilt resistance, or visible rust and pitting on the bearing races. These conditions compromise load control and mast stability.
