Eccentric bearings 0.2mm 2pcs

Fine Adjustment of the Rear Axle with NSR 0.2 mm Eccentric Bearings

When seeking the last tenth on track, preparation details make the difference. The NSR eccentric bearings with an eccentricity of 0.2 mm allow for surgical precision in modifying the height and position of the rear axle relative to the chassis, a key adjustment for controlling aerodynamic load, guide contact, and tyre grip depending on the layout and race conditions.

Function and Performance

The eccentric bearings replace standard bearings in the rear axle housings. By rotating them, they slightly displace the axle centre relative to the housing axis, resulting in a controlled change in the geometry of the rear end. With 0.2 mm of eccentricity, a subtle yet perfectly perceptible adjustment is achieved on track: ideal for fine corrections without drastically altering the car's balance.

Compatibility and Installation

These bearings are manufactured by NSR and are designed for use in the brand's own chassis and bancadas. To confirm exact compatibility with other third-party chassis or bancadas, we recommend checking the outer diameter of the bearing against the available housing before installation.

Installation is straightforward: they are inserted into the rear axle housing in place of the original bearings. Once installed, simply rotate them to the desired position and secure them to achieve the sought adjustment. Comparative testing on track is recommended to find the optimal point.

Installation and Preparation

To make the most of these eccentric bearings, consider the following aspects during car preparation:

1. Properly clean the housing of the bancada before inserting the bearings.
2. Test different angular positions of the bearing and note the results on track: small changes in orientation can have different effects depending on the layout.
3. Combine the adjustment with guide regulation and braid pressure for overall car balance.
4. Ensure that the rear axle rotates freely without rubbing against any chassis elements after installation.

Common Mistakes

One of the most common mistakes when working with eccentric bearings is applying the same adjustment to all layouts. The optimal eccentricity depends on the type of track (Scalextric, Ninco, Scaleauto, Carrera…), track load, and driving style. Another common error is not checking axial play after installation: a too-tight axle penalises top speed, while one with too much play generates imprecision in corners.

Frequently Asked Questions

What is the difference between a standard bearing and an eccentric one?

A standard bearing keeps the rear axle centred in its housing. An eccentric bearing displaces the axle centre relative to the housing centre, allowing for modification of the axle position in the chassis without changing the bancada or the chassis itself.

What is the purpose of the 0.2 mm adjustment?

The 0.2 mm eccentricity allows for fine adjustment of the rear axle height and tyre pressure on the track. It is a subtle modification, intended for competitive tuning, not for drastic geometry changes.

How many bearings do I need per car?

A rear axle has two housings (one on each side of the bancada), so you will need 2 bearings per car. This pack includes exactly 2 pieces.

Can I combine this eccentric bearing with a standard one on the same axle?

Technically it is possible, but for a symmetrical and predictable adjustment, it is recommended to install the same type of bearing on both sides. Combining them may create asymmetries that are difficult to compensate.

Are they compatible with bancadas from other brands?

NSR manufactures these bearings for its own systems. Compatibility with third-party bancadas will depend on the outer diameter of the bearing and the housing of each bancada. Always check the measurements before installation.

NSR eccentric bearings 0.2mm (pack of 2, ref. NSR4847-02) are precision-engineered components for slot car rear axle tuning. Designed to fine-tune rear axle height and geometry, these bearings are a key tool for competitive slot car preparation, compatible with NSR chassis and bancadas. Essential for club racers and serious hobbyists looking to optimise rear axle alignment on Scalextric, Carrera, Scaleauto or Ninco track systems.
