7200 Series Angular Contact Ball Bearing

7200 Series Angular Contact Ball Bearing

XEZ has been in research and manufacturing of machine tool spindle bearings since 1988, with the features of super precision, low-temperature rise, long service life, and low noise, which can reach 60000rpm and even higher speed. XEZ sealed spindle bearings are with grease inside, which can last for a long time. Users do not need to add any grease or oil by themselves, easy and convenient for operation and maintenance.

Additional information

Inner diameter range	10-130mm
Nominal contact angle	15°, 25°
Ball material	GCr15 or Ceramic(Si3N4)
Level	P2/P4S/P4/P5

Product Details:

XEZ 7200 series is one of the most representative bearings in angular contact ball bearings, which can bear radial load and axial load at the same time. It can work at higher speeds, and the larger the contact angle is, the higher the axial loading will be. High-quality ceramic balls are available with Chrome steel races so that to ensure a super accurate and long-lasting spindle bearing. Machine tool spindle bearings can be offered in standard sizes or customized sizes.

RAW MATERIAL

Race Material: Chrome steel(GCR 15)
Balls: G5 level ceramic balls, brand: AKS, SaitGoban, Coors Tec as per customers’ request.
Grease: Klueber # 72/73
Cage: PEEK, Nylon, Bakelite as per customers’ request.
