Our company supplies Japanese THK ball screws with various styles, complete lead models, and other transmission parts. THK products are on sale.
Specialty:
To meet the space-saving requirements, this model of ball screw has a standard screw shaft and nut. Standardize the end of the screw shaft to the support unit. Except for BNK0401, 0501, and 0601, which are fixed-free, the rest are fixed-support bases and are directly connected to the motor. Both the screw shaft and the nut have a small design. If it is used with supporting unit and nut seat, it can be directly assembled. Therefore, a high-precision feeding device can be easily obtained.
[Dust and lubrication]
Each nut has been filled with the right amount of grease. In addition, nuts above BNK0802 are equipped with labyrinth seals inside (BNK1510, BNK1520, BNK1616, BNK2020 and BNK2520 are also used as labyrinth seals by end caps). In addition, when foreign objects are likely to enter, the screw shaft must be completely covered with a dustproof device (such as a telescopic shield, etc.).
Ball screw rated life
Rated life, when moving a group of the same ball screw alone under the same conditions, is defined, where 90% of the total number of ball screws can be rotated without causing the material to peel off or rotate at a constant speed of.
High-quality ball screws manufactured according to JIS and other standards based on ball screw standards can calculate the rated life or rated load by applying standards such as JIS and ISO.
Lifetime calculation formula
L 10 [rev] = (C / P) p × 10 6
L 10 h [h] = (C / P) p × 16667 / n
L10: Basic rating life
C: Basic dynamic load rating [N]
P: dynamic equivalent radial load [N]
p: index ⇒ ball screw: p = 3, ball screw: p = 10/3
