Utility Slide Precautions on Use

Precautions on Use

1. The outer member and inner member stoppers are not designed to handle impact loads. Be certain to provide external stoppers at the stroke ends.
2. When installing this product, mount two slide rails on the wall as a set. Be certain to contact THK if you will be using only one slide rail or changing the mounting orientation to something other than what is indicated in the mounting orientation diagram.
3. The greasing interval varies depending on the usage conditions and environment. Ultimately, the greasing interval and amount of grease applied should be set using the actual device or machine.
4. Do not enter the movement range of moving parts while the device is operating or in an operable state. In particular, do not touch any moving parts during operation.
5. Stop the machine (turn off the power) before moving, installing, or performing a maintenance inspection on this product.
6. If performing an installation, maintenance inspection, or other task involving multiple people, confirm how to perform the work, what signals will be used, and how to handle problems before beginning, and assign another person to monitor the work.
7. Do not place anything on this product or its packaging. Do not apply a strong impact to this product.
8. Do not apply a load that exceeds the permissible load.
9. Do not disassemble or alter this product.
10. Securely fasten the product before use.
11. If an abnormality occurs, stop the machine immediately.
12. Do not use a product that is malfunctioning or broken.
13. Avoid impacts when transferring objects.
14. Contact THK if the product will be used in an environment outside of the specified temperature range.
15. Ball cages may become misaligned due to factors such as machine vibration. To realign ball cages, remove any borne load, then fully open and close the product. During realignment, it will take more force to move because the balls will be sliding. Exceeding the stroke range may cause components to break.
16. When installing the product, adjust the mounting so that the product runs steadily at a force of 15 N or less when not bearing a load.

Handling

1. Tilting a carriage or outer member may cause it to fall by its own weight.
2. Please use at least two people to move any product weighing 20 kg or more, or use a cart or another method of conveyance.
3. Do not disassemble the parts. This may result in loss of functionality.
4. Do not apply a load that exceeds the permissible load.

Use

1. When installing this product, wall-mount two units facing each other. If mounting a single unit on its own, please prepare a steady brace.
   If a mounting orientation other than the aforementioned is required, contact THK.
2. Placing a hand inside the outer member’s mounting holes may lead to the hand being caught between the carriage and outer member and cause injury.
3. When using joint products, confirm that the sliding resistance o f the joint portion will not fluctuate before mounting.
4. Do not apply an impact to the product when mounting. Doing so c an impair the function of wheels and other elements.
5. Prevent foreign materials, such as cutting chips or coolant, from entering the product. Failure to do so could damage the product.
6. Do not use the product at temperatures above 80°C. If used above this temperature, there is a risk that the resin and rubber parts may deform or become damaged.
7. If particles, liquids, or other substances adhere to the product, replenish the lubricant after cleaning the product.
8. Wear appropriate safety gear, such as protective gloves and safety shoes, when handling the product.
9. Do not stand on this product or its packaging. Do not apply a strong impact to this product.
10. If a stopper is added to prevent the carriage from coming off at the edge of the outer member, make sure that the stopper does not make contact with the carriage.
11. If this product breaks due to an accident or other cause, the carriage may come off of the outer member and fall. For the safe use of this product, take precautions such as adding a mechanism to prevent carriages from falling. Please use a mechanism that is structured in a way that it does not touch the product directly, because if an impact load is applied to an end plate or grease nipple, it may break and cause a malfunction.
12. For the carriage securing bolts, select a length that will leave some clearance between the tip of the bolt and the bottom of the tap hole so that the bolts don’t break through the lower surface of the hole. If the tip of a bolt breaks through the bottom surface of the tap hole, it can make contact with the wheels and damage them.

    

13. If the mounting material lacks sufficient rigidity or accuracy, the bearing load will be concentrated at one location and performance will dramatically decrease. Therefore, carefully consider the rigidity and accuracy of the housing and base as well as the strength of the securing bolts.
14. If the product will be used in a location with a lot of vibration, we recommend using a locking agent on the mounting screws.
15. If significant sliding resistance occurs along the stroke, it may be a result of how rough the mounting surface is, so it may be necessary to reexamine its machining accuracy.
16. If this product is used with a large displacement in the rollin g direction, it may not seal as well. If you want to improve its ability to form a seal, please conta ct THK.
17. If there are open spaces on the mounting surface for the outer member, the axial force of the screws may cause damage to the seating surface.Mount the outer member to a surface that does not have open spa ces.

    

18. Use the Tightening Torque Table on this page when securing oute r members and carriages.

Tightening Torque Table

• ¹ For the Model AWG18, use the included extra-low profile bolts (M4×8L) for fixing the outer member in place.If using bolts other than these, make sure that they are M4 extra-low profile hexagonal-socket-head bolts. Using other bolts can result in the bolts and the wheels making contact, which may cause damage.
• ² This is the tightening torque when the effective engagement length is 4.5 mm to 6.9 mm.
