The product lineup consists of a basic series from ISO specifications to a dedicated series for machine tools.
Has been filled with grease, with a ring of angular contact ball bearings have been formed series.
High-performance series Robust bearings, a strong lineup of products, ranging from high-rigidity series to ultra-high-speed products.
High precision angular contact ball bearings (standard series)
This is the ISO standard NSK precision angular contact ball bearings of the basic series.
Features:
Long life bearing steel (Z steel) as a standard material.
70 series, 79 series of products, but also with the ring, so that grease life increased to 1.5 times.
Depending on the type, there are two types of retainers.
High precision angular contact ball bearings (standard series)
High-speed angular contact ball bearings (Robust series)
This is the NSK set of proud of the material technology, evaluation technology and the essence of analytical technology developed support for high-performance high-performance machine tool products. In addition, with a series of products with high performance and long life characteristics, can improve the reliability of machine tools, and environmental performance, and can contribute to energy conservation.
Features:
High-speed angular contact ball bearings (Robust series)
Low heat, high speed.
The use of heat and abrasion resistance of the excellent SHX material production of X-type products, to achieve a high speed, long life.
According to different uses, established a different contact angle and ball material specifications of the powerful product lineup.
Bandwidth sealing ring, compared with open bearings, grease life increased to 1.7 times, to achieve a long life.
High-speed angular contact ball bearings (Robust series SpinShot Ⅱ)
The pursuit of refueling optimization, to achieve an unprecedented mute at the same time, to achieve a further high speed.
Features:
High-speed angular contact ball bearings (Robust series SpinShot Ⅱ)
Using oil and gas lubrication, in the NT # 40 level, to achieve 40000 per minute turn.
Compared with the previous oil and gas lubrication, reduce the noise of about 3 ~ 5dB.
Only about 1% of the previous oil and gas lubrication, that is, to reach the speed of 40000 revolutions per minute.
High precision angular contact ball bearings (BGR series)
This is a high-function series that can match the high-precision, ultra-high-speed rotation of the small shaft with a small diameter of 30mm.
Features:
High precision angular contact ball bearings (BGR series)
For the small axis of the design of ultra-high-speed bearings.
The use of heat and abrasion resistance of the excellent SHX material production of X-type products, to achieve a high speed, long life.
Standard uses high-precision specifications.
