A replacement library organized around how parts are identified.

Start with the marking, dimensions, nameplate, or application details you actually have. Each coverage area explains what to capture, what must match, and where a source-backed interchange claim is safe.

1. IdentifyCapture the exact part number, marking, dimensions, and interfaces.

2. CompareCheck duty, geometry, electrical or fluid requirements, and environment.

3. VerifySeparate a documented replacement from a candidate that still needs engineering review.

Coverage clusters8 active research areas

Rolling motion

Bearings & Seals

Identify bearings, mounted units, seals, and related components from a part number, designation, or measured dimensions.

Search intent: bearing replacement by number, bearing interchange, seal replacement, pillow block replacement, bearing dimensionsOpen guide →Power transmission

Belts, Chains & Couplings

Work from belt markings, measured length, chain designation, sprocket geometry, or coupling details before selecting a replacement.

Search intent: industrial belt replacement, V-belt size, timing belt replacement, roller chain replacement, coupling replacementOpen guide →Process equipment

Pumps & Fluid Handling

Identify pumps and fluid-handling parts by model, duty point, fluid, materials, connection, and operating conditions.

Search intent: pump replacement, pump cross reference, pump spare parts, mechanical seal replacement, pump model lookupOpen guide →Electromechanical

Electric Motors & Drives

Compare motors, gearmotors, drives, and starters using the nameplate and the complete mechanical and electrical interface.

Search intent: hydraulic component replacement, pneumatic cylinder replacement, hydraulic valve cross reference, hose assembly replacementOpen guide →

Quality boundary

One-stop does not mean one-size-fits-all.

Replacement Intelligence can organize the evidence across many part families. It should never turn a similar-looking number, dimension, or function into a drop-in compatibility claim without a source.
