Multiquip 040006304 Bearing 6304-C3

The Multiquip 040006304 Bearing 6304-C3 is a genuine OEM component designed for MTX, MT-E, and MTX-i series rammers, including the MTX80HDR, MTX70HDR, MTX70HD, MTX60HD, MTX60HF, MTX70HF, MTX50HD, MTX-i60, MT-E55, and MT85. As a direct Multiquip OEM part, the 040006304 is manufactured to the same tolerances and clearance specifications as the original, ensuring a correct drop-in installation with no guesswork on fitment. DHS Equipment stocks this part for fast fulfillment, so your rammer stays on schedule.

Key Features

• C3 Internal Clearance — Built for High-Cycle Impact Loads: — The C3 radial clearance rating accommodates the thermal expansion and shock loads typical of rammer operation, maintaining dimensional stability under repeated impact.
• Genuine OEM Specification: — Sourced directly from Multiquip, this bearing meets the original design tolerances for the 040006304 — no substitution guesswork, no mismatched specs.
• Broad Rammer Fitment: — Confirmed for MTX50HD, MTX60HD, MTX60HF, MTX70HD, MTX70HF, MTX70HDR, MTX80HDR, MTX-i60, MT-E55, and MT85 rammer models.
• Direct-Replacement Install: — Matches the original bearing position, bore, and outer diameter so it seats correctly into the existing housing without machining or shimming.
• Protects Crankshaft and Drive Train Alignment: — A correctly functioning bearing keeps the crankshaft centered and rotating freely; a worn bearing allows shaft deflection that accelerates damage to surrounding components.

A rammer bearing supports the crankshaft or exciter shaft, allowing it to rotate smoothly while absorbing the radial and axial forces generated by the machine's reciprocating motion. In a rammer, these forces are intense and repetitive — the bearing must maintain precise shaft alignment stroke after stroke to keep energy transfer efficient and prevent uneven wear on adjacent components. When a bearing begins to fail, operators typically notice increased vibration, unusual noise, or a loss of compaction force; left unaddressed, bearing failure can cause secondary damage to the crankcase or drive assembly that is significantly more costly to repair.
