Sealing and lubrication elements

Sealing and lubrication elements – system KIT

With their extensive range of standard accessories, the linear guidance systems can be easily used in numerous areas. Since the guidance systems are used in an extremely wide variety of applications, however, additional requirements are often placed on the sealing and lubrication components.

Application-oriented complete package

If the standard components are not adequate for reliable operation and a long operating life, it is possible to draw on a finely graduated system of sealing and lubrication elements. These special access­ories protect the rolling element system of the guidance systems against contamination and ensure long relubrication intervals even under the most demanding operating conditions.

KIT structure

The elements are configured as the system KIT and are designed for various application conditions.

Starting from the degree of contamination, the best combination in each case can be quickly and easily compiled:

  • Possible combinations, see link
  • Description of sealing elements, see link
  • Overview of sealing elements, see link
  • Description of lubrication elements, see link.
ACHTUNG

Only a proportion of the KITs can be retrofitted. Parts that cannot be retrofitted must be ordered together with the linear recirculating ball bearing and guideway assembly and are supplied already fitted.

Degree of contamination

The degree of contamination will vary depending on the market sector, the application and the environmental conditions.

ACHTUNG

The definitions at this point, see table, are therefore only an initial aid in the selection of KITs.

Definition of the degree of contamination

Degree of contamination

Very slight

Slight

Moderate

Heavy**

Clean environment.

Coarse (large) metal swarf

Clean environment

No cooling lubricants.

Coarse (large) metal swarf

Slight exposure to, for example, cooling lubricants.

Hot swarf
(metal, aluminium)
of widely varying size and shape, including very small swarf from HSC machining

Aggressive media and dust as well as cooling lubricants.

**If this degree of contamination is present, a KIT can give only a restricted level of protection. Additional measures implemented by the customer, such as additional covers on the guidance system, will give a considerable increase in the operating life.

Sealing elements

The following additional sealing components are available:

  • End plates, see link
  • End wipers, see link
  • Additional wipers, see link
  • Sealing strips, see link.

End plates

End plates are corrosion-resistant, non-contact components, ➤ Figure. They protect the end wipers located behind them against, for example, coarse contaminants and hot swarf.

There is a narrow gap between the guideway and the wiper.

 End plate,

End wipers

End wipers are contact seals that are fixed to the end faces of the carriage. End wipers protect the guidance system against the ingress of contaminant particles and can extend the relubrication intervals. The selection of the suitable sealing system is based on the application of the guidance system. End wipers are available in a single lip design (as standard) and are made from special high performance materials, ➤ Figure.

Single lip end wipers have a seal lip oriented outwards that protects the carriage against the ingress of contaminant particles. In combination with oil lubrication, the single lip end wiper facilitates the rinsing out of contaminant particles (flushing effect).

Additional wipers

In addition to the standard seal, other additional wipers may be used behind each other (cascading arrangement). These are screw mounted in front of the first wiper on the carriage, ➤ Figure.

The additional wipers are of a single lip design and are made from a special high performance material.

Sealing strips

Sealing strips are contact components that are fitted to the lower longitudinal sides of the carriage, ➤ Figure. They protect the rolling element system against contamination and loss of lubricant.

Lubrication elements

End piece without upper relubrication hole

The designation of the KITs can also be used to order end pieces of the carriage without an upper relubrication hole (end number -..3), ➤ Figure.

ACHTUNG

At the time of ordering, it should be determined which KITs are required.

End pieces without upper relubrication hole  KIT.KWSE..-..3

Configuration of KIT.KWSE

Unless indicated otherwise, the locating face is defined as being at the top. The KIT designation is given in the sequence left/centre/right. If no KIT numbers are indicated, the standard version will be supplied, see link.

KIT components can be fitted on the left, centre and right of the carriage, ➤ Figure.

Retrofitting by the customer

The KITs available for retrofitting by the customer are indicated accordingly as retrofittable in the KIT tables, see link.

KIT left, right

The KIT components are identical for all carriage designs. The KIT end number -..3 describes the end piece without upper relubrication holes, ➤ Figure. The end piece (lubrication distributor plate) is not a KIT component, so the KIT end number -..3 is not taken into consideration in retrofitting by the customer.

KIT components for retrofitting by the customer must be ordered for all types and designs using the designation KIT.KWSE.. as well as the suffix -OS and the KIT end number -..0.

The scope of delivery includes the wear components and fixing screws required for retrofitting.

Example: KIT.KWSE35-OS-300.
