Angewinder Offset 1.25 Motor Mount Bearings

Slot.it anglewinder mount with 1.25 offset and integrated bearings for 1/32 scale competition builds

The SICH131B2 motor mount from Slot.it is a mount specifically designed for anglewinder configurations, with an offset of 1.25 mm and included bearings. This type of mount positions the motor at an angle relative to the rear axle, allowing for optimal weight distribution and drivetrain layout in 1/32 competition chassis.

Function and performance

The mount is the structural element that secures the motor to the chassis and determines the geometry of the drivetrain. In an anglewinder configuration, the angle of the motor directly affects the position of the crown gear and pinion, and therefore the efficiency of the drivetrain and the mass distribution of the car. The 1.25 mm offset adjusts the lateral position of the power unit relative to the rear axle, allowing for fine-tuning of the alignment between pinion and crown gear to reduce friction and improve power transfer.

The integrated bearings in this mount ensure smoother and more durable axle rotation, reducing energy loss due to friction compared to standard bushings. For those seeking a careful and durable setup, incorporating bearings into the mount is one of the common steps in the serious preparation of a competition slot car.

Compatibility and installation

This motor mount is a reference from Slot.it's modular system, designed to integrate with their 1/32 scale chassis and bodies. Before purchasing, it is advisable to verify that the 1.25 mm offset is suitable for the chassis and the crown/pinion combination you are using, as Slot.it offers different offset options to cover various drivetrain geometries.

• Configuration: anglewinder (motor at an angle to the rear axle)
• Offset: 1.25 mm
• Includes bearings
• Scale: 1/32
• Reference: SICH131B2
• Brand: Slot.it

Preparation and installation: aspects to consider

When installing the mount, it is important to check the correct seating of the bearings and the alignment of the motor before permanently securing the assembly. A slight misalignment between pinion and crown gear can result in vibrations, noise, or premature wear of the gears. Slot.it recommends using their own crown gears and pinions to ensure optimal geometric compatibility with this mount.

If you are preparing the car for club or championship competition, periodically checking the condition of the bearings and the play of the power unit is part of the regular maintenance to keep performance at the highest level.

Frequently asked questions

What is the difference between anglewinder, sidewinder, and inline?

In the anglewinder configuration, the motor is positioned at an angle to the rear axle. In the sidewinder, the motor runs parallel to the rear axle (transversely). In the inline, the motor is perpendicular to the rear axle, in line with the car, which allows for a lower centre of gravity. Each configuration has its advantages depending on the chassis and the track.

What is the purpose of the 1.25 mm offset in a mount?

The offset determines the lateral displacement of the motor relative to the rear axle. A 1.25 mm offset adjusts the position of the pinion in relation to the crown gear to achieve correct engagement and minimise friction, which directly impacts the efficiency of the drivetrain.

Do the bearings come pre-installed in the mount?

Yes, this SICH131B2 reference includes bearings, unlike other Slot.it mounts that come with standard bushings. This facilitates installation and ensures smoother axle rotation from the outset.

Is it compatible with all Slot.it chassis?

This mount is designed for Slot.it's modular system in 1/32 scale. Before installing it, it is advisable to confirm compatibility with your specific chassis and the crown and pinion combination you are using, as the offset must match the geometry of your drivetrain.

Can I use this mount on Sport track?

The mount is an internal component of the chassis and does not depend on the type of track. It is valid for both Sport track and other systems, as its function is to secure the motor to the car chassis, not to interact with the track.

The Slot.it SICH131B2 is an anglewinder motor mount with 1.25 mm offset and integrated bearings, designed for 1/32 scale slot car competition builds. A key upgrade for serious racers looking to optimise drivetrain geometry, reduce friction and improve power transfer on their Slot.it chassis. Compatible with Slot.it's modular system and ideal for club racing and competitive setups.
