Link Ball Precautions on Use

Service Temperature

The service temperature of the Link Ball series is basically between ‒20℃ and 80℃. If the service tempera- ture exceeds this range, contact THK. (See examples of testing the product at temperature other than the above service temperature range on Durability Tests with Link Ball Model BL .)

Handling

  1. Do not disassemble the parts. This will result in loss of functionality.
  2. Take care not to drop or strike the Link Ball. Doing so may cause injury or damage. Giving an impact to it could also cause damage to its function even if the product looks intact.
  3. When handling the product, wear protective gloves, safety shoes, etc., as necessary to ensuresafety.

Precautions on Use

  1. Do not use the product in the manner that the permissible tilting angle is exceeded since doingso may damage the product.
  2. Prevent foreign material, such as cutting chips or coolant, from entering the product. Failure todo so may cause damage.
  3. Model BL is designed for use under loading in radial direction, while model RBI is designed foruse under loading in axial direction.
  4. Insufficient rigidity or accuracy of mounting members causes the bearing load to concentrate on one point and the bearing performance will drop significantly. Accordingly, give sufficient consideration to the rigidity/accuracy of the housing and base and strength of the fixing bolts.

Lubrication

  1. Lithium soap group grease No. 2 is contained in all boots and can be used without further greas-ing.
  2. Do not mix different lubricants. Mixing greases using the same type of thickening agent may still cause adverse interaction between the two greases if they use different additives, etc.
  3. When using the product in locations exposed to constant vibrations or in special environments such as clean rooms, vacuum and low/high temperature, use the grease appropriate for the specification/environment.

Storage

When storing the Link Ball, enclose it in a package designated by THK and store it in a room whileavoiding high temperature, low temperature and high humidity.

Disposal

Dispose of the product properly as industrial waste.
