ME BM4-59

Frequently Asked Questions

Q: What are the exact dimensions of the ME BM4-59 bearing?
A: The ME BM4-59 precision bearing has a 20 mm bore diameter, 47 mm outside diameter, and 14 mm width. These dimensions are critical for wheel hub fit and load capacity. Verify your pallet jack wheel cavity specifications match before ordering.

Q: Which manual pallet jack models use the ME BM4-59 bearing?
A: The ME BM4-59 is compatible with standard load wheel assemblies on manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and similar OEMs. Confirm your equipment model fits the 20 mm bore and 47 mm outer diameter specification.

Q: What is the load rating for the ME BM4-59?
A: Load capacity depends on bearing type (deep groove ball or angular contact), preload, and sealing design. Verify dynamic load rating in the detailed specification sheet. Overloading the bearing will cause premature failure and increased wheel noise.

Q: What material and seals does the ME BM4-59 use?
A: The ME BM4-59 is constructed from high carbon chromium steel (SAE 52100 bearing steel) with dual rubber seals. Dual seal design provides superior protection against moisture, dirt, and contamination, extending bearing life in warehouse and cold storage applications.

Q: How long will the ME BM4-59 bearing last in service?
A: Under normal warehouse loads and regular wheel maintenance, the ME BM4-59 typically lasts 3-5 years before wear becomes noticeable. Inspect wheels quarterly for grinding noise or drag. Replace immediately if spinning resistance increases or the wheel locks up.

Q: Is there a cross-reference part number for the ME BM4-59?
A: Cross-reference numbers exist across different OEM suppliers. The ME designation indicates our house brand equivalent. Contact us with your original equipment manufacturer and model year if you need exact cross-reference information.
