Conti SilentSync B-1960

Conti SilentSync B-1960 – synchronous belt with low vibration and stable operation

Conti SilentSync B-1960 is a timing belt for industrial drives, where the HOT tooth shape helps the belt to run stably and self-centering in the correct SilentSync pulley. The product has a working length of 1960mm, latitude code B and a belt width of 35mmThe belt is an endless, self-aligning SilentSync belt, where the HOT tooth shape provides a gradual tooth engagement and contributes to stable belt movement in suitable drives.

SilentSync differs from many common timing belts in that it has a self-aligning HOT tooth shape. This makes the product family particularly relevant in drives where noise, vibration and stable belt movement are of great importance. The variant's data is particularly relevant in belt drives where smooth operation, precise timing and uniform power transmission are important.

Technical data for this SilentSync timing belt

This variant is a 14M belt with HOT tooth shape. The length of 1960mm and the width of 35mm are key measurements for the belt geometry and its engagement with the pulley. The number of teeth is 140, calculated from the working length and tooth pitch of 14 mm. The number of teeth and tooth pitch determine the synchronous engagement of the belt in the pulley.

The width code in the product name is not accidental. The SilentSync series uses letter codes, where Y, W and P belong to the 8M widths, while B, G, O and R belong to the 14M widths. This structure links letter code, length, tooth pitch and width together in the product logic of the SilentSync system.

Benefits of HOT profile and SilentSync technology

SilentSync is designed to make synchronous belt drives quieter and less vibrating. HOT stands for Helical Offset Tooth, and the tooth shape provides a smoother engagement with the pulley. When the belt and pulley are properly matched, this tooth shape can help reduce belt travel and provide smoother operation than many straight timing belt drives.

• The synchronous tooth profile means that the belt maintains the relationship between the motor and the driven shaft.
• Aramid reinforced construction is relevant in drives with requirements for stable power transmission.
• The belt is designed for quiet and low-vibration operation.
• The profile and width code makes it easier to identify the correct variant.
• Continental SilentSync is intended for timing belt pulleys that fit the HOT profile.
• The belt is self-centering and can therefore help reduce belt movement problems in suitable drives.

This does not mean that the belt alone can solve all problems in a drive. If the pulleys are worn, the shafts are misaligned, or the tension is incorrect, noise, heat, or wear can still occur. However, in a properly constructed SilentSync drive, this type of belt is a strong solution when low noise levels, precise timing, and maintenance-free operation are important factors.

Profile, length and width in this variant

The Conti SilentSync B-1960 is built around HOT 14M-profile with a tooth pitch of 14 mmThe working length is 1960mm, the belt width is 35mm, and the belt has 140 teeth. The combination of profile, tooth pitch, length and width determines how the belt engages with the associated SilentSync/Eagle pulleys.

The latitude code B (blue) is part of the SilentSync system design and links the belt width to a specific color and letter code. In a properly designed drive, the belt's HOT tooth shape works together with the pulley profile to ensure gradual and stable tooth engagement. This is especially important in synchronous belt drives where the belt must maintain a precise relationship between the motor and the driven shaft without slippage.

The endless construction provides a uniform belt without joints, and the self-guiding geometry contributes to smooth belt movement in suitable installations. The technical dimensions of the belt should therefore be seen as an overall specification: HOT 14M, 1960mm, 35mm and 140 teeth belong together in this specific variant.

Use for this CONTI® SilentSync timing belt

The product is suitable for belt drives requiring a timing belt with low noise, low vibration and self-aligning belt travel in a correctly dimensioned drive. This length and width make the belt relevant for industrial drives, fans, pu and machines where a wider belt and larger tooth pitch may be relevant. However, the final suitability always depends on the pulley, axle distance, load, speed and the machine design. SilentSync is suitable for horizontal drives where the self-centering function, low noise level and low-vibration operation are relevant properties.

SilentSync may visually resemble other timing belts, but the HOT profile distinguishes it from regular HTD and standard profiles. The difference is that SilentSync uses the HOT profile, which is made for SilentSync/Eagle pulleys. Length and width therefore do not describe the entire compatibility alone. The profile must also fit the pulley, the profile has an impact on belt travel, noise level, wear and power transmission.

Installation and operation of the belt drive

When installing, the pulleys must be clean, properly aligned and designed for the SilentSync/HOT profile. A new timing belt cannot compensate for worn pulleys or misalignment. The belt tension must also be correct. Too low a tension can cause tooth skipping or unstable operation, while too high a tension can strain the bearings, shafts and the belt itself.

The SilentSync belt is maintenance-free as a belt type and does not require lubrication. This is one of the advantages compared to chain drives, where lubrication is often part of the maintenance. However, this does not mean that the drive can be ignored. Check regularly for noise, vibration, uneven running, rubber dust, heat or visible wear. These signs may indicate that the belt drive is not working optimally.

Questions about properties and use

Why does SilentSync have color codes?

The color codes are related to the available widths. This makes it easier to identify the belt width and profile family.

What does HOT mean?

HOT stands for Helical Offset Tooth, which is central to the SilentSync belt's self-aligning and low-noise properties.

Is this belt endless?

Yes, the products in this SilentSync series are fixed length endless timing belts. They are not open meter belts.

Which pulleys should be used?

SilentSync should be used with pulleys that match the HOT profile, tooth pitch and belt width. Regular pulleys should not be assumed to fit.

Compatibility and operating conditions

SilentSync is not an ordinary HTD belt. The belt uses the HOT tooth shape and is designed for pulleys with a corresponding SilentSync/Eagle profile. When the belt and pulley are matched, the tooth shape can contribute to lower noise, less vibration and more stable belt operation than many traditional straight timing timing belt drives.

• The HOT profile must work with pulleys that fit the SilentSync/Eagle system.
• The tooth pitch on 14 mm determines the distance between the teeth and must correspond to the profile of the pulley.
• The belt width on 35mm affects the contact surface and load capacity of the specific drive.
• The working length of 1960mm and the number of teeth on 140 defines the synchronous circumference of the belt.
• Correct alignment, appropriate belt tension and clean pulleys have a major impact on noise, heat generation and service life.
• Limited oil resistance should be understood as a technical limitation; the belt is not intended as a universal chemical-resistant solution.

If the drive is loaded incorrectly or the pulleys are worn, noise, heat, misalignment or abnormal wear can occur. These conditions are often caused by the entire belt drive setup and not just the belt itself. The SilentSync belt works best in a properly sized drive where the profile, pulleys, tension and load match.

Relationship between belt and pulley

In a synchronous timing belt drive, the belt and pulley work as one system. The tooth shape, tooth pitch and belt width have an impact on how the load is distributed in the engagement. For this variant, this means that HOT 14M-profile, tooth pitch on 14 mm, the working length of 1960mm and the belt width on 35mm must be viewed together.

The HOT geometry is designed to have a more gradual tooth engagement than a traditional straight tooth shape. This can provide a smoother transition between belt and pulley, which is a key part of the SilentSync concept’s low noise and vibration levels. The belt’s properties are best utilized when the belt drive is properly aligned and the load is within the drive’s design.
