Mitoos MXL z83 timing belt

Mitoos MXL z83 Toothed Belt: Precise and Slip-Free Transmission for Your Slot Setup

When belt transmission comes into play in a slot chassis, every tooth counts. The Mitoos MXL z83 toothed belt (ref. CXM483) is designed to work in perfect harmony with the entire range of Mitoos toothed pulleys, ensuring constant grip even at the highest RPMs.

Features and Function

• Number of Teeth: 83
• Width: 2 mm
• Standard Pitch: MXL
• Compatible with Mitoos toothed pulleys made of plastic (ref. M136 to M140) and aluminium (ref. M143 to M149)
• High RPM transmission between shafts without loss of traction

Function and Performance

MXL pitch toothed belts are a proven solution in slot preparations when seeking to transmit power between two shafts with minimal energy loss and without the noise or wear associated with conventional pinions and crown gears. The standardised MXL tooth profile ensures that the coupling with the pulley is precise, without play that generates vibration or imprecision in throttle response.

With 83 teeth, this belt offers a specific circumference length that makes it suitable for specific axle spacing configurations. Before installation, it is advisable to check the centre-to-centre distance of your chassis' axles to confirm that z83 is the correct measurement.

Compatibility

The CXM483 belt fits directly with the entire family of Mitoos toothed pulleys:

• Plastic Pulleys: references M136, M137, M138, M139, and M140
• Aluminium Pulleys: references M143, M144, M145, M146, M147, M148, and M149

The use with aluminium pulleys is particularly interesting in competition setups where reducing mass on the shafts and improving acceleration response is desired.

Installation and Preparation

For optimal operation, the belt must be installed with the right tension: neither too loose, which can cause tooth skipping, nor too tight, which increases friction and premature wear. In belt transmission systems, it is common to have some mechanism for adjusting axle distance; ensure that your chassis allows this before selecting the belt length.

It is not necessary to lubricate MXL toothed belts in indoor slot applications. Excess lubricant can attract dust and reduce grip on the teeth.

Common Mistakes

• Choosing the belt by the number of teeth without measuring the axle distance: the number of teeth determines the total length of the belt; an incorrect measurement will make installation impossible or leave the belt with inadequate tension.
• Mixing pulleys of different pitches: ensure that both the driving pulley and the driven pulley are MXL pitch to guarantee correct coupling.
• Installing the belt with excessive tension: shortens the component's lifespan and generates unnecessary heat in the transmission system.

Frequently Asked Questions

What does "MXL pitch" mean in a toothed belt?

MXL pitch is a standardised specification for miniature toothed belts. It defines the distance between teeth (0.080 inches, approximately 2.032 mm), ensuring interchangeability between manufacturers that adhere to this standard.

Which Mitoos pulleys is this belt compatible with?

It is compatible with the entire range of Mitoos toothed pulleys: the plastic ones (M136–M140) and the aluminium ones (M143–M149), as long as the pitch is MXL.

How do I know if the number of teeth z83 is suitable for my chassis?

You need to measure the centre-to-centre distance of the motor and rear axles of your chassis. Based on that measurement and the MXL pitch, you can calculate or consult belt selection charts. Mitoos offers various lengths (different z values) to fit different chassis geometries.

Can this belt be used with pulleys from other brands that are also MXL?

In theory, yes, as long as the pulley width is compatible with the 2 mm of the belt and the pitch is genuinely MXL. However, to ensure optimal fit, Mitoos recommends using its own pulleys.

How often should the belt be replaced?

It depends on usage. In competition with intense sessions, it is advisable to check it periodically for wear on the teeth or micro-cracks. In recreational use, the lifespan is considerably longer. Having a spare belt in the pit is always good practice.

The Mitoos MXL z83 toothed belt (CXM483) is a precision timing belt for slot car transmission systems, featuring 83 teeth and a 2 mm width with MXL pitch. Fully compatible with the complete range of Mitoos toothed pulleys — both plastic (M136–M140) and aluminium (M143–M149) — it delivers reliable, slip-free power transfer at high RPM. An essential component for slot car builders and racers working with belt-drive chassis setups.
