BTM 85 AT/P4CDBA Super-precision, high-speed design double direction angular contact thrust ball bearing

Super-precision,two-direction angular contact ball bearings are used for bi-way axial positioning on the spindle of the machine tool.They accommodate high axial loads in both directions , mainly in two design forms: BTW (basic series bearings, which can withstand high axial loads) and BTM (high-speed series bearings, which can withstand high speed).

–Accommodate axial loads in both directions

–Maximum speed capability

–30° contact angle for higher speeds or 40° contact angle for higher degree of axial rigidty
