Telescopic Full extension DTS-48 | up to 166 kg | Schock Metall HEAVY
Material:
The telescopic slides are manufactured by milling from cold drawn material of quality C45E + C according to EN 10277.
The standard ball cages are made of galvanized sheet metal.
Carbon steel C85, G100 according to DIN 5401 are used as standard balls.
Tolerances:
The general manufacturing tolerances of telescopic slides are in accordance with js13 standard for bores and linear dimensions. Straightness is 1 mm/m and twist is 1 degree/m.
Standard surface treatment is an electrolytic zinc coating according to ISO 2081, which confirms the European RoHS regulation with a zinc coating of at least 8 and an average of 12 microns.
A yellow zinc coating is also available on request.
Operating temperatures:
Standard working temperatures are between -30 and + 110 degrees C. Beyond this temperature range, special adjustments should be made to ensure smooth operation ,e.g. the use of specific grease for high or low temperatures.
Load capacities:
The telescopic slides offer a high degree of load capacity and compact dimensions. The maximum load capacity is given on fully extended pairs of slides, installed in the main axis direction and with the load evenly distributed over the inner slide.
The load capacities per pair indicated in this catalog include such a high safety margin that the rails are suitable for multiple applications. The safe working load depends on the extension, the type of carriage and mounting, and the frequency of use/number of cycles. This means that a longer extension limits the safe load. When mounting the slides in secondary axis arrangement, the safe working load is reduced by approx. 40% depending on the slide.
Installation:
In our product sketches and family tables you will find the most important dimensions including drilling diagrams.
Maintenance:
The rail design allows for minimal maintenance operation in most environments, with only extreme operating conditions requiring additional maintenance.
Mounting in dirty environments:
The telescopic slides are supplied without protection against dust. There is a risk that the presence of contamination in the rails will quickly lead to jamming or premature wear of the rail components. Therefore, it is important to provide mounting in a largely dust and particle free environment. Otherwise, the user must provide external measures for protection.
Deflection:
Deflection is an elastic deformation measured in mm when the rails are uniformly loaded, fully extended and mounted on the main axis.
When mounted on the secondary axis, the deflection is increased.
The maximum deflection of the telescopic slides is 1% of the closed length.
Speeds:
The limits of the speed is determined by the mass of the intermediate element that must be pulled by the moving element. The speed decreases as the length of the carriage increases. The recommended speed of use of the telescopic slides is 0.3 m / s.
Rules for good assembly
1. Make sure that the slides are parallel and mounted on the main axis.
2. Use all supplied mounting options on the rail.
3. Make sure that the mounting surfaces are flat and level.
4. Apply evenly distributed load.
5. Aligning the fronts of the slides
Following the mounting rules will ensure that the slides run smoothly and evenly, and that they have an optimum service life.
When mounting on the secondary axis, the load capacity is reduced by 40% compared to the basic load.
The telescopic slides cannot be used for vertical mounting (up and down), overhang, excessive heat, corrosive environment or dust.
Maintenance and Lubrication:
The telescopic slides are supplied with a light lubrication, additional grease can be added if required to allow optimum life.
Under normal working conditions, it is recommended that the slides be lubricated at least every 20,000 cycles, although this will depend greatly on the actual conditions and atmosphere of the application.
In critical working conditions, the slides must be lubricated more frequently.
Before lubrication, the slides must be cleaned free of dirt and debris. With the slide open, spread a sufficient amount of medium consistency lithium grease on the races between the inner and outer beams and then in the space between the ball bearings.
When used in aggressive conditions (humidity, dust, abrasive materials, etc.), ensure regular maintenance with complete cleaning of the telescopic slides followed by lubrication.
