Single-lip eccentric bearings 1.1mm

Precision adjustment with NSR single flange eccentric bearings — 1.1 mm

Within the range of NSR spare parts for 1/32 scale, eccentric bearings are one of the most valued components by tuners. The eccentricity allows the rotation axis to be shifted relative to the geometric centre of the bearing, resulting in very fine control over chassis height and tyre pressure on the track. The 1.1 mm single flange variant (reference nsr4805-11) occupies a precise position in that adjustment scale.

Function and performance

The eccentric design of these bearings means that by rotating them within their housing, the rear axle is slightly displaced in height. That small movement —here 1.1 mm— has a direct and measurable impact on:

• The chassis height relative to the track, with a direct effect on aerodynamics and friction.
• The load on the rear tyres and, therefore, the available traction during acceleration.
• The behaviour in corners, especially in tight radius turns where load balance is crucial.

The single flange finish facilitates assembly and adjustment without the need for specialised tools, while maintaining the dimensional precision that characterises NSR spare parts.

Compatibility and assembly

These bearings are designed for use in 1/32 scale slot cars that incorporate housings compatible with the NSR standard. Before assembly, it is advisable to check that the chassis housing accepts this format of eccentric bearing and that the 1.1 mm eccentricity fits within the adjustment range you need for your setup.

Assembly is straightforward: insert the bearing into its housing and rotate it until reaching the position that provides the desired chassis height. It is recommended to perform adjustment tests with the car on a flat surface before securing the final position.

Assembly and preparation

• Clean the housing before inserting the bearing to avoid play due to dirt or remnants of old lubricant.
• Use a bearing wrench or a suitable flat-head tool to rotate the bearing without forcing the flange.
• Check the eccentricity visually or with a gauge before closing the chassis.
• If you are looking for a more aggressive or softer adjustment, NSR offers eccentric bearings in different eccentricity values so you can choose the one that best suits your tuning needs.

Common mistakes

• Confusing eccentricity: each value (0.3 mm, 0.5 mm, 1.1 mm…) produces a different effect. Make sure to select the one that corresponds to the adjustment you are looking for.
• Assembling without checking the housing: a worn housing can nullify the effect of eccentricity. Check the condition of the chassis before assembly.
• Securing before testing: it is advisable to conduct at least one test session with the provisional adjustment before finalising the position.

Frequently asked questions

What does "single flange" mean in this bearing?

It refers to the design of the outer edge of the bearing. The flange serves as a positioning stop within the housing. The single flange version is the most common in standard adjustment applications in 1/32 scale chassis.

What exactly is the purpose of the 1.1 mm eccentricity?

The eccentricity determines how much the rotation axis can be displaced when the bearing is rotated. With 1.1 mm, a notable adjustment of height and load is achieved, suitable for setups that require significant correction from the neutral position of the chassis.

Is it compatible with any NSR chassis?

These bearings are designed for 1/32 scale chassis with housings compatible with the NSR standard. Check the technical sheet of your chassis or the NSR spare parts catalogue to confirm compatibility before purchasing.

Do I need any special tools to assemble them?

It is not strictly necessary, although having a specific tool for bearings makes adjustment easier and prevents damage to the flange during installation. NSR and other brands in the sector offer compatible insertion tools.

Can I combine bearings of different eccentricity on the same axle?

Technically it is possible, but it is not the usual practice in tuning. It is most advisable to use the same eccentricity value on both sides of the axle to achieve symmetrical and predictable behaviour.
