ConCar - V-belt B 136 / 3450 Li 17x11 mm

Product overview

This B-type belt from ConCar features the classic 17 × 11 mm profile and an inner length Li of 3,450 mm. The belt is therefore designed for use with compatible B-type pulleys and appropriately designed drives. When replacing a belt, the existing belt size should be checked based on profile and length to ensure the new belt fits completely within the existing pulley.

With a length of 3,450 mm, this version belongs to the upper size range within the B-series offered here. Such longer lengths are used in appropriately dimensioned drives; the specific design, the pulleys, and the drive power remain decisive.

Standard profile and dimensions

The B-profile is a classic V-belt according to DIN 2215 / ISO 4184. Its cross-section measures 17 × 11 mm. The flank angle of the classic V-profile is 40°. The specified Li-length refers to the inner length of the specific belt.

• Profile: B
• Cross-section: 17 × 11 mm
• Internal length Li: 3,450 mm
• Effective length / reference dimension Ld: 3,490 mm
• External length La: 3,519 mm

Construction and materials

The B-belt is a classic, wrapped V-belt. The tensile cords for load transmission run inside the rubber body, while the outer fabric protects the belt surface. The source describes the B-belt as heat-resistant, oil-resistant, and antistatic. This makes it suitable for environments where dust, oil, or elevated temperatures may be present.

Key features and benefits

• 17 × 11 mm classic B-profile
• Internal length Li 3,450 mm with the specified Ld/La values
• Designed for use with suitable B-type pulleys
• Suitable for agriculture, industry, pumps, fans and conveyor technology

Typical applications

B-type V-belts are frequently used in agricultural machinery, industrial fan and pump drives, as well as in manufacturing and conveyor systems. The wide profile is designed for classic B-type pulleys and is used in numerous machine designs.

• Agricultural machinery
• Fan and blower drives
• Pumps and compressors
• industrial manufacturing and conveying systems

Assembly and tension

Before replacing the belt, first check that the profile and length of the existing belt match this model. When fitting the new belt, ensure it sits securely in all grooves. After tensioning, check the belt's movement to ensure it runs centered without any unusual noise or lateral movement.

Drive design

When designing a belt system, factors such as the drive unit's power output, rotational speeds, center distances, number of belts, and pulley design must be considered, in addition to the belt size. The individual belt length alone does not indicate the power that can be transmitted.

Maintenance and lifespan

The lifespan of a V-belt depends heavily on correct tension, proper alignment, and suitable pulleys. Dirt, incorrect tension, and damaged pulleys can accelerate wear. Therefore, when replacing a belt, not only the belt itself but also the condition of the pulleys should be checked.

storage

A suitable storage location protects the belt from moisture, direct sunlight, heat, and oily contaminants. This ensures that the fabric and rubber components remain in a condition suitable for their intended application until installation.

Comparable designations from other manufacturers

Comparable classic V-belts are also offered by manufacturers such as Gates, Optibelt, Continental, and Megadyne. However, for a direct replacement, brand names alone are not the deciding factor; rather, the belt must match the profile, length, and requirements of the existing drive system.

Frequently Asked Questions

What does Li mean?
Li stands for the inner length of the V-belt. For this item, the specified inner length is 3,450 mm.

How do I identify the correct size?
The key factors are profile B, the inner length Li of 3,450 mm, and the matching pulley. The additional length specifications Ld and La serve to clearly define the size.

Can a different brand of belt be used?
For a replacement, the profile and length must match and be compatible with the existing drive. The brand alone is not a sufficient selection criterion.

Delivery

You will receive the selected ConCar V-belt in the specified profile and length. The specifications B, B 136, 3.450 Li and 17 × 11 mm mentioned in the product name are decisive for the order. Availability is indicated separately in the shop.
