Description

The BECA 006/B profile is a roll of tape that can be cut to a specific length according to the customer's specification. Tapes or guide strips can be made with "integrated" embossing. The embossing is a set of lubricant pockets (also callsed teardrop structures), which improves the friction. Several types of cuts can be made.

Advantages

Substantial and improved lubrication conditions through the teardrop structures
Very good friction coefficient; no stick-slip effect
Good wear resistance; very long life
Increased absorption of foreign particles
Easy to fit
Good vibration absorption

The following formula calculates the linear length and accounts for the gap "Z" necessary at the ends of the tape after fitting. This gap "Z" offsets the thermal expansion under the effects of temperature, and prevents intermediate pressures and drag pressures in the system.

In the piston guide:
L (mm) = π x (ØD1 - E) - Z

In the rod guide:
L (mm) = π x (Ød1 + E) - Z

where:

L = Length of the guide tape (mm)
ØD1 = Piston diameter (mm)
Ød1 = Rod diameter (mm)
E = Thickness of the tape (mm)
Z = Gap after fitting

L = Length of the tape L (mm) Tolerances of L (mm)

Types of cuts

The wear rings are made with a 30° angle cut as standard. Other types of cuts can be made on request, as shown in the diagram below.
