Features:
Produce the best bearings is the eternal pursuit of Kent Bearings.
(1)Low noise: noise level detection, the decibel value of miniature bearings is <23 decibels, the decibel value of micro and small bearings is <25 decibels, and the decibel value of small bearings is <27 decibels, which is much lower than that of the peers.
(2)High speed: Bearing micron-level size control, p5 error < 6 microns, strong consistency, can be matched according to product requirements, to meet dozens of to 20,000 revolutions, or even higher speed requirements
(3)Durability: Control from raw materials, use more wear-resistant Xingcheng steel and Northeast special steel, and have a longer service life.
(4) Working Temperature: It can be used in a temperature environment from -60℃ to 230℃ and is being developed for a 300℃ temperature environment application, with low temperature resistance and high temperature resistance, and the application field is expanded.
