Frequently Asked Questions
Q: What are the exact dimensions of bearing 20906?
A: Bearing 20906 has an inner diameter of 20 mm, outer diameter of 47 mm, and width of 14 mm. These dimensions are critical for wheel hub fitment. Verify your pallet jack wheel hub bore diameter and axle shaft size match these specifications before ordering.
Q: Which manual pallet jack models use bearing 20906?
A: Bearing 20906 is compatible with multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Cross-reference your specific pallet jack model and year with the bearing dimensions to confirm fitment.
Q: What material is bearing 20906 made from?
A: Bearing 20906 is manufactured from through-hardened chrome alloy steel (SAE 52100 equivalent) with a hardness rating of 58 to 64 HRC. The cage is reinforced nylon (polyamide) retainer material. Dual rubber seals provide contamination resistance. This construction ensures high precision and long service life in warehouse material handling applications.
Q: How long will bearing 20906 last in normal warehouse use?
A: Under normal warehouse conditions with typical loading, bearing 20906 typically lasts 5 to 10 years or longer. Lifespan depends on daily load cycles, floor surface conditions, moisture exposure, and maintenance practices. The sealed design extends service life by protecting against contamination and moisture.
Q: Is bearing 20906 a direct replacement for other bearing part numbers?
A: Bearing 20906 is a high-precision sealed assembly designed as a direct replacement for compatible manual pallet jack wheel hubs with matching 20 mm inner diameter, 47 mm outer diameter, and 14 mm width specifications. Verify the original bearing part number or cross-reference through our parts catalog to confirm compatibility with your specific pallet jack model.
Q: What is the load rating for bearing 20906?
A: Bearing 20906 is designed for manual pallet jack wheel hub applications supporting typical loads of 2000 to 5000 pounds per bearing depending on whether it is a load-bearing wheel or steer wheel position. The through-hardened chrome steel construction and sealed design provide durability for repeated loading cycles typical in warehouse environments.
