The Multiquip 0204102063 Bearing Ball Upper ST-4100 is a genuine OEM upper ball bearing designed for the Multiquip ST-4100 concrete pump. As a direct OEM replacement, it is manufactured to the same specifications as the original component, ensuring a correct fit within the pump assembly. This bearing is sourced directly through Multiquip's authorized parts network, so you can order with confidence knowing you're getting the right part for your ST-4100.
Key Features
- OEM-Grade Bearing Tolerances — Manufactured to the same dimensional and load-rating specifications as the original, maintaining correct shaft alignment and rotational integrity within the pump drive assembly.
- Drop-In Installation — Engineered to seat directly into the upper bearing position of the ST-4100, matching the original mounting interface without rework or modification.
- Confirmed ST-4100 Fitment — Verified for the Multiquip ST-4100 swing-tube concrete pump; always cross-reference part number 0204102063 before ordering.
- Sustains Pump Drive Performance — A correctly functioning upper ball bearing keeps the pump's rotating components running smoothly under load; a worn bearing leads to shaft play, vibration, and accelerated wear on surrounding components.
- Genuine Multiquip OEM Part — Supplied as an authentic OEM component, ensuring material grade and geometry match what was originally installed at the factory.
The upper ball bearing in a concrete pump supports the rotating shaft that drives the pumping mechanism, carrying both radial and axial loads generated during operation. It keeps the shaft centered and stable, allowing the pump to move concrete consistently without excess vibration or heat buildup. When this bearing wears or fails, operators will typically notice increased noise, shaft wobble, or erratic pump output — all signs that prompt replacement is needed to prevent further mechanical damage.
