BTR series spindle bearings

The BTR series is a high-speed thrust angular contact ball spindle bearing with a contact angle of 40 °. It is a non separable back-to-back pairing and has higher rigidity than the BAR series (30 °). It is suitable for high rigidity, bi-directional axial load, and high-speed low heat precision spindle scenarios. It can be interchanged with the 2344 series and is often used in combination with cylindrical roller bearings.
