ConCar - V-belt B 279.5 / 7100 Li 17x11 mm

Product overview

The ConCar B-profile V-belt is designed for classic belt drives using a 17 × 11 mm cross-section. With an inner length of 7,100 mm, this version is tailored to a clearly defined drive geometry. The profile transmits power to the pulley via flank contact and is used in industry, agriculture, and for pump, fan, and machine drives.

With a length of 7,100 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: 7,100 mm
• Effective length / reference dimension Ld: 7,140 mm
• External length La: 7,169 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 7,100 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

During installation, the belt is placed on the pulley without tension and then tensioned according to the specifications of the respective drive. The pulleys should be aligned and clean. The belt must not be forced over the pulleys with tools, as this can damage the tensile cords.

Drive design

The selection should always be based on the existing drive system. The profile geometry of the pulleys, the required belt length, and the system's performance data are crucial. This article refers to a specific belt size; the actual drive system design is based on the machine's technical specifications and the pulleys used.

Maintenance and lifespan

Maintenance typically involves regular visual inspections for cracks, frayed fabric, unusual wear, or damage. Unusual noise or visible slippage can also indicate incorrect tension or a worn belt.

storage

For storage, a dry, clean place without direct UV radiation and without contact with oil or other substances that could damage the belt material is recommended. The belt should be stored in its natural shape and not permanently deformed.

Comparable designations from other manufacturers

Those looking for an alternative name can search for the corresponding classic profile and length at Gates, Optibelt, Continental, or Megadyne. A specific brand association should not be inferred solely from the name; the technical dimensions and drive design are the determining factors.

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 7,100 mm.

How do I identify the correct size?
The key factors are profile B, the inner length Li of 7,100 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 279.5, 7,100 Li and 17 × 11 mm mentioned in the product name are decisive for the order. Availability is indicated separately in the shop.
