Product Description
Cone, bearing with rubber seal
Frequently Asked Questions
Q: What is the difference between SKU 447-046 and a standard bearing cone?
A: SKU 447-046 is a bearing cone with an integral rubber seal. The seal protects the bearing races from dirt, moisture, and debris ingress, extending bearing life in wet or dirty environments. Standard cones without seals require more frequent relubrication and are prone to contamination failure.
Q: Which forklift models does SKU 447-046 fit?
A: This sealed bearing cone is compatible with electric and internal combustion forklifts from Crown, Toyota, Raymond, Yale, Hyster, and other major manufacturers. It is typically used in rear or side wheel assemblies exposed to moisture or yard debris. Verify bore diameter and cup matching before ordering.
Q: What is the rubber seal material and does it require maintenance?
A: The rubber seal is typically Nitrile (NBR) or similar elastomer designed for general duty. Seals do not require maintenance but can wear or crack after 3 to 5 years. If the seal appears cracked or missing, replace the entire cone-and-cup assembly. Do not attempt to reuse a cone with a damaged seal.
Q: How does the seal improve bearing performance compared to unsealed cones?
A: The rubber seal reduces relubrication frequency by 50 percent and extends bearing life by 1 to 2 years in wet or contaminated environments. Sealed bearings are ideal for outdoor yards, cold storage, or wet-wash areas. Unsealed cones are adequate for dry indoor environments but require monthly relubrication and quarterly inspection.
