2-3 Precautions on Use
Prevent dust
zPrevent foreign materials, such as cutting chips or coolant, from entering the product. Failure
to do so could damage the product.
zPrevent foreign materials, such as cutting chips, coolant, corrosive solvents or water from
getting in the product by using a bellows or cover when the product is used in an environment
where such a thing is likely.
zIf foreign materials such as cutting chips adhere to the product, clean the product and then
replenish the lubricant.
zSmall strokes can inhibit the formation of an oil film between the raceway and the area of
contact for rolling elements, resulting in fretting. Therefore, be sure to use a type of grease
with high fretting resistance properties. We recommend periodically adding stroke movement
raceway and the rolling elements.
Maximum temperature
80°C
Max
zDo not use this product if the external temperature exceeds 80 °C. If used in excess of this
temperature, there is a risk that the resin and rubber parts may deform or become damaged
(except the heat-resistant type).
Handle with care
zDo not forcibly drive a pin, key, or other positioning device into the product. This could create
indentations on the raceway and impair the product's functions.
zInserting the shaft while tilted risks foreign material entering, internal parts being damaged,
zUsing while the rolling elements are removed may cause early damage.
zA lack of rigidity and accuracy of mounting components may cause the bearing load to
the rigidity and accuracy of the housing and base, and the strength of the securing bolts.
Falling objects
zIf any of the rolling elements fall, discontinue use and contact THK.
