SW Offset 1.0mm Motor Mount Bearings

Adjust your transmission to the millimetre with the Slot.it SICH115B motor mount

The SICH115B is the Slot.it motor mount designed for Sidewinder configurations — that is, with the motor positioned parallel to the rear axle — with an offset of 1.0 mm and housings for bearings. A precision component aimed at those who leave nothing to chance in the preparation of their slot car.

Function and performance

The motor mount is the part that determines the exact position of the motor within the chassis and, by extension, the distance between pinion and crown gear. An offset of 1.0 mm allows for a slight lateral displacement of the motor from the central position, facilitating the adjustment of backlash (the play between pinion and crown gear) until the optimal engagement point is found. A gear mesh that is too tight generates friction and heat; too loose, vibration and loss of traction. With this mount, that balance is in your hands.

The incorporation of bearings in the mount significantly reduces friction compared to mounts with plastic or bronze bushings, resulting in a more efficient transmission, less heat in the components, and a noticeable improvement in motor response, especially during long competition sessions.

Compatibility

This mount is designed for the Slot.it modular chassis system, compatible with the Sidewinder motor configurations of the brand. If you equip your Slot.it chassis with pinions and crown gears from the same family, the SICH115B fits within the ecosystem of interchangeable parts that characterises this brand, known for its excellent availability of spare parts and tuning components.

Before mounting, check that the 1.0 mm offset is suitable for the combination of pinion and crown gear you are using. Slot.it offers mounts with different offset values so you can choose the one that best fits your drivetrain.

Installation and preparation

• Check the condition of the bearings before installation; they should spin smoothly and without excessive radial play.
• Apply a minimal amount of specific lubricant for bearings to them, without overdoing it to avoid contaminating the crown gear or pinion.
• After installation, check the gear mesh by turning the axle by hand: it should roll smoothly but without noticeable play.
• If the gear mesh is too tight or too loose, Slot.it offers mounts with other offset values to correct it precisely.

Common mistakes

• Installing the mount without checking the wear of the bearings: a worn bearing negates the advantages of the component and can damage the axle.
• Confusing offset with motor height: the offset laterally displaces the motor, not vertically. It does not replace the height adjustment of the chassis.
• Mixing mounts with different offsets without recalculating the gear mesh: if you change the crown gear or pinion, the optimal offset may vary.

Frequently asked questions

What does "1.0 mm offset" mean in a motor mount?

It indicates that the motor shaft is displaced 1.0 mm from the central reference position. This displacement allows for the adjustment of the distance between pinion and crown gear to achieve precise engagement without excessive friction.

Why choose a mount with bearings over one with bushings?

Bearing mounts offer lower friction, greater durability, and better performance at high revolutions. In cars prepared for competition, the difference in efficiency and operating temperature is clearly noticeable.

Is it compatible with any Slot.it chassis in Sidewinder configuration?

It is designed for the Slot.it modular system. Check compatibility with your specific chassis, as the brand's chassis family is extensive and some models may require specific mounts.

What is the difference between Sidewinder, Inline, and Anglewinder?

In the Sidewinder configuration, the motor is parallel to the rear axle (transverse). In Inline, the motor is perpendicular to the axle (longitudinal), lowering the centre of gravity. In Anglewinder, the motor is positioned at an angle to the axle. This mount corresponds to the Sidewinder configuration.

Can I combine this mount with pinions and crown gears from other brands?

In principle, it is possible if the tooth modules match, but we recommend using components from the same brand to ensure precise engagement and proper system operation.

The Slot.it SICH115B motor mount is a precision part for Sidewinder configurations, featuring a 1.0 mm offset and integrated bearings for optimised gear mesh and reduced friction. An essential upgrade for slot car racing enthusiasts looking to fine-tune their drivetrain, compatible with Slot.it modular chassis systems. Perfect for club racing, home competition, and serious slot car preparation.
