Gardette industries, manufacturer of parallel keys since 1925

A key is a mechanical part used to connect two rotating elements, such as a shaft and a pulley or a gear, thus allowing the transmission of movement and force.

It comes in various forms, such as Disc key, the Straight end key or even the 2-round end key.

Keys are essential in many industries to ensure a reliable and durable connection between mechanical components.

What are the different types of parallel keys?

The parallel key is the most popular and most used key model.

It has a rectangular body that fits into specific grooves. Parallel keys offer ease of assembly and disassembly. This allows them to be used in various sectors such as the mechanical industry, drive technology, transmission and many other areas.

What is a B shape key?

Norms and standards for a din 6885 form B parallel key

  • Din 6885: The din 6885 standard specifies the dimensions and tolerances of parallel keys.
  • Form B: It specifies the shape and the machining process used to manufacture these straight end keys. The B-shaped key is characterized by its straight ends, which reduces stress concentrations and allows better load distribution.

The B-shaped key is designed to fit perfectly into a groove machined in the shaft and the mounted element. Key dimensions vary according to assembly specifications and industry standards.

Key standards reflect the interchangeability and standardization of mechanical components.

This ensures that components made by different manufacturers are compatible, which is essential for repairs and replacements.

Materials for the manufacture of B shape keys

In 90% of cases, the keys are made of carbon steel, stainless steel, or aluminum alloys, but in case of specific needs, we can manufacture custom keys in specific materials.

  • carbon steel : very resistant but likely to rust.
  • Stainless steel : resistant to corrosion but more expensive.
  • Aluminum alloys : lightweight but less resistant than steel.

Process for manufacturing B-shaped keys

  • Drawing, rolling and shot blasting: cold processing of steel to obtain the final section.

  • Cut: cutting the key to the desired length and shape.

  • Finishing: creating grooves, recesses, and other shapes to create rectangular edges and keep the key in position.

  • Tribofinishing: controlled wear to improve surface condition and eliminate burrs.

  • Some text processing
    • Heat treatments to modify mechanical properties.
    • Surface treatments to protect against corrosion.

  • Quality: systematic control of raw materials, semi-finished and finished products.

  • Logistics and packaging: packaging and delivery planning.

  • Delivery: shipping to the customer according to the agreed terms.

Difference between a B shape key and other types of keys

A-shape key

La A-shape key is similar to the B shape, but differs in its flat shape without rounded edges. It is used in applications where a tighter fit is required.

C shape key

The C-shaped key, on the other hand, has a half-moon section, which allows easier installation in certain configurations. It is often used in assemblies where frequent uninstallation is required.

Detailed comparison

Compared to shapes A and C, the form B key offers a compromise between ease of installation and robust assembly. It is particularly appreciated for its ability to reduce play and maintain accurate alignment.
