Details

Product Name: Bearing Bush / Support Ring (Part No. CP022010/527)

Description:
This component is a precision bearing bush (also referred to as a support ring or bearing bushing) manufactured from brass . It is a critical structural and alignment component specifically designed for the CP022001/2 and HT022012/172 series BFT waterjet intensifier pumps . Its primary function is to maintain precise concentricity between the reciprocating piston (plunger) and the high-pressure cylinder bore. By providing a rigid, low-friction bearing surface, it ensures smooth axial movement, absorbs radial loads, and prevents metal-to-metal contact. It is rated for continuous operation at 4,137 bar (60,000 PSI) .

Applications:

Provides radial support and alignment for the reciprocating piston within the high-pressure cylinder assembly .
Maintains the critical coaxial alignment necessary for proper seal function and pump efficiency.
Used during major pump overhauls or when cylinder alignment is compromised.
Compatible with BFT, WJS, Maximator Jet, STM, and Intermac Primus intensifier systems .

Features:

Brass Construction: Offers excellent wear resistance, low friction against steel components, and superior corrosion resistance in the waterjet environment .
Precision-Machined: Manufactured to exacting tolerances to ensure a perfect fit in the cylinder bore and correct alignment of the plunger.
Critical Alignment Component: Directly responsible for maintaining plunger concentricity, which is vital for seal life and pressure stability.
Semi-Wear Component: Subject to mechanical wear and alignment stress over thousands of hours but is more durable than elastomeric seals.
OEM Compatibility: Direct replacement for the CP022010/527 bearing bush, listed in official BFT parts diagrams . Cross-references include 1-16388 , 5300002 , and IP4008 .

Maintenance:

Failure Diagnosis (When to Replace):

Reduced Cutting Pressure: A worn bush allows the plunger to wobble, breaking the oil film seal and causing a loss of high pressure .
Excessive Vibration/Noise: Unusual knocking or rattling from the pump area indicates excessive clearance in the bearing or plunger assembly .
Premature Seal Failure: Frequent seal failures (e.g., U-cup, backup rings) often suggest the bearing bush is allowing too much plunger deflection .
Visible Damage: During a major overhaul, inspect the inner surface for scoring, galling, flaking of the brass material, or ovality.

Inspection and Replacement Guidelines:

Full Depressurization (Critical): Before any maintenance, lock out the main electrical disconnect, fully depressurize the high-pressure water and hydraulic circuits, and follow lockout/tagout procedures.
Disassembly: Remove the high-pressure cylinder and plunger assembly to access the bearing bush inside the cylinder bore .
Clean Installation: Clean the cylinder bore meticulously. Even microscopic grit trapped behind the bush can cause misalignment.
Lubrication: Lubricate the bush inner diameter with clean hydraulic oil or high-pressure grease during reassembly to prevent scoring during the first strokes.
Measurement: Measure the inside diameter of the bush. If it exceeds the manufacturer's specified limit for the plunger clearance, it must be replaced.
Replace as a Set: It is often advisable to inspect the plunger (CP022004/220) [citation:??] and the wear ring (XF56/220) simultaneously. A worn plunger will rapidly wear out a new bush.
Torque Compliance: Ensure the cylinder end cap is torqued to the specification in the manual; improper torque can distort the cylinder bore and pinch the bearing bush.
