Mitoos MXL z74 timing belt

Precise and Slip-Free Transmission: the Mitoos MXL z74 Toothed Belt

The Mitoos MXL z74 toothed belt (ref. CXM474) is a standardised MXL-profile drive component, designed for setups that require exact synchronisation between shafts at high revolutions. With 74 teeth and 2 mm width, it fits precisely into the entire range of Mitoos toothed pulleys, ensuring smooth operation and slip-free performance.

Features and Function

• Standardised MXL Pitch: standardised tooth profile, ensuring a clean and repeatable engagement on each lap.
• 74 Teeth: appropriate belt length for common transmission setups in the Mitoos range.
• 2 mm Width: measurement tailored to the brand's toothed pulleys, with no lateral play that could cause vibrations or misalignment.
• High Tensile Strength: designed to operate at high revolutions without deformation or tooth skipping under load.

Compatibility

This belt is specifically designed for use with Mitoos toothed pulleys, both plastic (references M136 to M140) and aluminium (references M143 to M149). The fit is precise across the range, simplifying installation and eliminating the need for additional adjustments.

Installation and Preparation

For optimal performance, it is essential that the belt is correctly tensioned: neither loose — which causes tooth skipping at high rpm — nor excessively tight, as this would increase friction and premature wear of the teeth. Check the alignment of the pulleys before closing the assembly; any lateral deviation subjects the belt to lateral stress that shortens its lifespan. In competitive setups, it is advisable to periodically check the condition of the belt, especially after long running sessions.

Frequently Asked Questions

Which Mitoos pulleys is this belt compatible with?

It is compatible with the entire range of Mitoos toothed pulleys: both plastic (M136-M140) and aluminium (M143-M149). In both cases, the fit is direct, with no need for adapters.

What does MXL pitch mean?

MXL is a standardised tooth profile for precision drive toothed belts. It ensures dimensional compatibility between manufacturers that adhere to the standard, although it is always advisable to use the brand-specific pulleys to ensure optimal fit.

When should I replace the belt?

The most common signs of wear are: tooth skipping at medium or high revolutions, irregular noise during transmission, or visible deformation on the tooth flanks. In intensive or competitive use, periodic inspection extends the life of the other transmission components.

Can I use this belt with pulleys from another brand that are also MXL?

In theory, MXL pitch is an open standard. However, small tolerance differences between manufacturers can affect the fit. To ensure specified performance, we recommend using it with Mitoos toothed pulleys.
