The return piece for the HBN is based on the circulating mechanism that picks up balls in the near tangential direction. The nearly ideal circulating mechanism allows balls to run unforcedly. It enables the use of the return piece and the ball cage designed to provide sufficient strength, under the DN value rated at 130,000.
The use of a ball cage eliminates ball-to-ball friction,offering higher durability, lower dynamic torqua fluctuation, and smoother motion.
The use of a ball cage eliminates collision noise. The return piece has no lips and picks up balls and is also capable of suppressing collision noise. It contributes to implementing operation under lower noises.
