Eccentric bearings 0.6mm 2pcs

Fine Adjustment with NSR 0.6mm Eccentric Bearings

Eccentric bearings are one of those spare parts that make a real difference when tuning a slot car. The 0.6mm eccentricity allows for slight displacement of the motor shaft relative to the rear axle, thereby modifying the tension between pinion and crown gear without the need to adjust the motor pod. A fine and effective tuning tool.

Function and Performance

The eccentric bearing replaces the standard bearing in the motor housing. By rotating it, the centre of the motor shaft is displaced by the amount indicated by the eccentricity — in this case, 0.6mm — varying the mesh between pinion and crown gear. This allows for:

• Reducing the play between pinion and crown gear for a more direct and efficient transmission.
• Slightly increasing that play when seeking greater smoothness in running or using specific gear ratios.
• Compensating for small irregularities in the motor pod or chassis without the need for machining.

In competition, the correct adjustment of the mesh is crucial: too tight generates friction and heat; too loose causes noise, premature wear, and loss of power. With these bearings, the exact point is reached quickly and without complex additional tools.

Compatibility and Installation

These eccentric bearings are a reference from the NSR catalogue, a brand specialised in spare parts and precision mechanics for slot cars. To confirm the exact compatibility with your motor pod and configuration, consult the technical documentation from NSR or contact our team.

Installation is straightforward: insert the bearing into the motor housing of the pod and rotate until the desired mesh between pinion and crown gear is achieved. It is recommended to always check the result with the complete car before fixing the final position.

Considerations

• The pack includes 2 units.
• The eccentricity is 0.6mm, providing a moderate adjustment range, ideal for precise corrections without drastically altering the geometry.
• NSR offers eccentric bearings in various eccentricities; choose the one that best fits your current configuration.
• For optimal tuning, combine the adjustment of the eccentric bearing with the correct selection of the pinion-crown gear ratio for your motorisation.

Frequently Asked Questions

What is the exact purpose of the 0.6mm eccentricity?

It indicates the maximum displacement of the motor shaft relative to the centre of the housing. With 0.6mm, the mesh between pinion and crown gear can be varied within that range, allowing for fine adjustment without modifying the motor pod.

Is it compatible with any slot car pod?

It depends on the diameter of the bearing housing in your pod. We recommend consulting the technical sheet from NSR or contacting us to confirm compatibility with your specific configuration.

How many units are included in the pack?

The NSR4847-06 pack includes 2 units of 0.6mm eccentric bearings.

Can it be used with any type of motorisation (Sidewinder, Inline, Anglewinder)?

In principle, yes, as long as the bearing housing in the pod is compatible. The eccentric bearing is especially useful in configurations where the adjustment of the mesh is critical, such as in Sidewinder or Anglewinder motors with little margin for adjustment in the pod.

Is any special tool required for installation?

No. The bearing is inserted by hand into the housing and rotated to select the desired position. However, it is recommended to verify the mesh with the assembled car before finalising the adjustment.
