Description

The BECA 006 Piston profile is a machined guide ring with a 30° angle cut as standard made from filled PTFE or PE-UHMW, depending on the type of application. We can offer these rings with an "integrated" embossing (also called teardrop structures). The embossing is a set of lubricating pockets that enable an improvement in friction. Other 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
Good vibration absorption
No water absorption for the PE-UHMW

Design guidelines

Guide sizing

The following formulas calculate the height "H" of the piston guide holder while taking account of the gap "Z" necessary at the ends of the ring after fitting. This gap "Z" offsets the thermal expansion under the effects of temperature, and prevents intermediate pressures and drag pressures in the system.

H = (F x f) / (ØD1 x Cr)

where:

H = Min. height of guide (mm)
F = Max. radial force (N)
f = Safety coefficient (we recommend 2)
ØD1 = Bore diameter (mm)
Cr = Permissible radial load in dynamic applications (N/mm²)

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.
