Timken 12Y46250 Commercial Vehicle Leather Wheel Seal with Severe Duty Wear Ring

The Timken 12Y46250 is a premium commercial vehicle leather wheel seal kit designed for trailer axle applications requiring maximum durability and protection in severe operating conditions. This seal kit features an advanced polymer-impregnated leather sealing lip combined with a severe duty wear ring to provide superior performance in demanding commercial vehicle environments.

Key Features:

• Polymer-Impregnated Leather Lip: Absorbs grit and contaminants while providing exceptional sealing across a broad temperature range from -65°F to 170°F (-55°C to 77°C)
• Oversized Double-Walled Metal Construction: Heavy-duty outer diameter prevents seal spinning or walking out of the hub bore while enabling effective heat transfer away from the sealing lip
• Severe Duty Wear Ring: Provides a new running surface for worn or damaged axle spindles and protects the spindle from damage during hub removal
• Superior Material Compatibility: Outperforms nitrile seals in cold, contaminated environments and is compatible with all natural and synthetic oils and greases
• Precision Engineered: Manufactured to OE specifications using high-grade materials and precision tolerances for consistent performance

This seal kit is engineered specifically for trailer axle wheel-end applications where contamination, extreme temperatures, and spindle wear are concerns. The black bore sealant included with the double-walled construction ensures a secure fit and optimal sealing performance. Cross-references include STEMCO 372-7097 and is compatible with A/AM-BBS bearing sets.
