Steel Ball Bearing 1x3x1mm - Precision Bearing for Model Building

Precision running in the smallest possible format

Play, wear and stiff-running axles are the greatest enemies of a finely finished model. The Steel Ball Bearing 1x3x1mm solves this with a genuine bearing-supported pivot of only 3 mm outer diameter — exactly where a plain hole or bush falls short.

Key features

• Shaft diameter 1 mm — an exact fit on standard 1 mm model-building axles
• Outer diameter 3 mm — extremely compact, fits the narrowest construction
• Thickness 1 mm — minimal installation width, ideal where space is limited
• All-steel construction — high load capacity and a long service life
• Close tolerance — virtually no play, so a stable, true run

Applications

Model cars and the MCC car system

• Bearing support for steered front axles
• Wheel and rear axles of running model cars
• Drivetrains and small gear transmissions

Model building and model railways

• Pivot points of moving structures, cranes and turntables
• Small mechanical drives and transmissions
• Hinged parts that move frequently

Installation in three steps

1. Step 1 — Clean the housing hole and size it correctly: 3 mm for a close fit.
2. Step 2 — Press the bearing squarely into the hole, applying pressure to the outer ring only.
3. Step 3 — Slide the 1 mm shaft into the bearing and check that everything turns freely and smoothly.
