Key Features

• Genuine OEM Sealing Integrity — Manufactured to the exact material thickness and compression profile required for proper bearing cavity sealing in DCA series alternator assemblies.
• Drop-In Alternator Fit — Engineered to seat correctly against the bearing housing without trimming or shimming, supporting a clean, leak-free reassembly.
• Broad DCA Series Compatibility — Fits DCA180, DCA220, and DCA250 generator models, including Tier 4 final, ultra-silent, and standard diesel-powered variants.
• Protects Bearing Longevity — A properly seated bearing gasket prevents contamination ingress and lubricant loss at the bearing interface, directly supporting alternator bearing service life.
• Critical Electrical System Component — Maintaining a correctly sealed bearing cavity reduces heat buildup and vibration-related wear, supporting consistent generator output and alternator performance.

The bearing gasket forms a precision seal between the bearing housing and the alternator end frame on DCA series generators. Its primary role is to prevent lubricant from escaping the bearing cavity while blocking dust, moisture, and debris from entering — both of which can accelerate bearing wear and lead to alternator failure. When this gasket deteriorates or is improperly installed, bearing contamination and lubricant loss can cause increased operating temperatures, abnormal noise, and ultimately bearing seizure, resulting in generator downtime.
