Double Direction Axial Angular Contact Ball Bearings BTM Series
Bearings of BTM Series consist of two non-separable single row angular contact ball bearings arranged back to back, to carry thrust loads in both directions. When mounted, the bearings become preloaded.
These high speed design bearings are available with fitted with 30° contact angle or 40° contact angle.
They have the same bore and outside diameter as bearings in the 2344(00) series, but a 25% lower bearing height, which makes them particularly suitable for very compact arrangements. They do not have the same high load carrying capacity and axial stiffness as bearings in the 2344(00)series,but can operate at higher speeds.
BTM series bearings are capable of high speed operations and lower heat generation whiles maintaining high rigidity. BTM series bearings with special width dimension bearing spacer can successfully replace the 2344 series bearings in case of unchanged with shaft and bearing housing.
