Frequently Asked Questions
Q: What electric lift truck models use the 331212 felt seal?
A: The 331212 felt seal is specified for electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other major OEM manufacturers. Confirm your lift truck model and the specific assembly location where this seal is installed.
Q: What is the function of the 331212 felt seal?
A: Felt seals contain lubricant and prevent dirt, moisture, and contaminants from entering bearing and axle assemblies. The 331212 is positioned on mast, wheel, or drive axle components where it maintains grease retention and protects against environmental ingress.
Q: What material is the 331212 felt seal made from?
A: The 331212 is constructed from compressed wool or synthetic felt material, which absorbs and retains lubricant while filtering particulates. Felt material degrades over time when exposed to heat, moisture, and friction, requiring periodic replacement.
Q: How long does the 331212 felt seal last?
A: Felt seal lifespan typically ranges from 18 months to 3 years depending on operating temperature, lubrication frequency, and contamination levels. Replace the seal if you observe grease leakage, increased bearing noise, or visible cracking and hardening of the felt material.
Q: What are the dimensions of the 331212 felt seal?
A: Felt seal bore diameter, outer diameter, and thickness are specified for your lift truck assembly location. Measure your existing seal or reference your lift truck parts documentation for exact dimensions. Incorrect size will result in improper fit and seal failure.
Q: Are there alternative part numbers for the 331212 felt seal?
A: The 331212 is the primary OEM designation. Equivalent cross-references may exist for specific lift truck models. Provide your lift truck model, serial number, and assembly location for confirmed alternatives or compatible replacements.
