The Multiquip 363916 is a genuine OEM Outer Bearing Cone designed for the LS-series hydraulic-driven concrete pumps, including the LS300, LS400, LS500, LS600, LS40D, LS40TD, LS50TD, and LS60TD. As a direct OEM replacement, part 363916 meets the original engineering tolerances required to maintain smooth, low-friction rotation within the pump's drivetrain. Sourcing a verified OEM component ensures the correct taper geometry and load rating for your specific LS-series machine. DHS Equipment stocks this part to help keep your concrete pump operating at full capacity.
Key Features
- Taper-Matched OEM Tolerancing — Manufactured to the exact cone angle and race dimensions specified for the LS-series drivetrain, ensuring proper bearing load distribution under the high cyclic stresses of concrete pumping.
- Drop-In Replacement — Seats directly into the original bearing housing on LS-series pumps with no machining or modification to the housing bore.
- Broad LS-Series Compatibility — Confirmed fitment across LS300, LS400, LS500, LS600, LS40D, LS40TD, LS50TD, and LS60TD hydraulic concrete pump models.
- Sustained Pumping Output — A correctly seated bearing cone allows the pump's drive components to maintain consistent rotational alignment, preserving output pressure and volume across long pours.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip's OEM supply chain under part number 363916, carrying the same material specification as the original production component.
The outer bearing cone is the inner race half of a tapered roller bearing assembly, working together with the bearing cup to transfer radial and axial loads from a rotating shaft into the surrounding housing. In a hydraulic concrete pump like the LS-series, this bearing supports the drive shaft under the continuous, high-load cycling that pumping aggregate-laden concrete demands. When the cone wears or loses its seating geometry, the shaft develops play, which accelerates wear on surrounding components and can lead to loss of pumping efficiency or unexpected drivetrain failure.
