50 tooth timing belt

MXL Timing Belt for Demanding Slot Mounts

The 50-tooth timing belt (ref. PSP-BD50MXL) from Sloting Plus is designed for drive systems that use MXL pitch pulleys. With a thickness of just 1.8 mm, it occupies minimal space within the chassis and allows for smooth and virtually silent power transfer from the motor to the rear axle, without the vibrations or wear associated with metal gear systems.

Function and Performance

The timing belt drive is a highly valued alternative in slot preparations when aiming to reduce friction, dampen torque spikes, and achieve a more progressive response from the powertrain. The MXL geometry is one of the most common pitches in this type of application: the teeth are small and uniform, ensuring a precise fit with the pulley and eliminating play between components.

• 50 teeth: determines the total length of the belt and conditions the gear ratio along with the number of teeth on the motor and axle pulleys.
• 1.8 mm thick: compact profile that facilitates integration into chassis with limited space.
• MXL pitch: compatible with pulleys of the same pitch, both on the motor and rear axle.

Compatibility and Installation

For the belt to work correctly, it is essential that both pulleys —the motor and the rear axle— are also of MXL pitch. The mounting tension directly influences performance: too much tension generates friction and heat; too little tension causes tooth skipping. Adjust the axle distance until the belt has a slight controlled slack, without excessive looseness.

Before installation, ensure that the alignment of both pulleys is perfect in the horizontal plane. Even minimal misalignment can cause premature wear on the side of the belt or even its dislodgement during operation.

What type of setup is it suitable for?

This type of belt fits well in preparation projects where an alternative drive system to pinion-crown is chosen, especially in inline configurations or when the chassis design allows it. It is a common solution in handcrafted prototypes and in some club competition chassis where different gear ratios are experimented with.

Frequently Asked Questions

Can I combine this belt with any MXL pulley on the market?

Yes, as long as the pulley is of MXL pitch. What you need to verify is that the number of teeth on both pulleys is compatible with the length of this belt (50 teeth) and with the axle distance of your chassis.

How long does a timing belt last under normal usage conditions?

It depends on the mounting tension, motor power, and frequency of use. With correct adjustment and a moderately powered motor, the lifespan is long. It is advisable to inspect it periodically for cracks or worn teeth.

Is the 50-tooth belt the only option available?

Sloting Plus offers timing belts in various tooth counts to accommodate different axle distances and gear ratios. Check the complete catalogue to find the length that best fits your setup.

Is it necessary to lubricate the belt?

No. Timing belts operate dry. The application of lubricant can attract dirt and degrade the belt material, reducing its lifespan and grip on the pulley teeth.

The PSP-BD50MXL toothed belt from Sloting Plus is a 50-tooth MXL pitch drive belt, 1.8 mm thick, designed for slot car drivetrains using MXL pulleys. It offers smooth, quiet power transmission with minimal friction, making it a popular choice for custom chassis builds and club-level competition setups where belt drive systems are preferred over traditional pinion-crown gear arrangements.
