Single Row Angular Contact Bearings-Ktaiballbearing

Single Row Angular Contact Bearings can withstand axial load in one direction, the radial load, it will cause additional axial force must be applied to the corresponding reverse load. Therefore, the types of bearings are generally used in pairs.

bearing material: chrome steel GCr15/52100/100Cr6
bearing tolerance: P0(ABEC-1), P6(ABEC-3), P5(ABEC-5), P4(ABEC-7)
contact angle: C-15^。, AC-25^。, B-40^。, A-30^。,
different angles are available on request.
Type code:
7-the counter bored outer ring
S7-the outer ring is separable
SN7-the inner ring is separable
B7-the stepped inner ring

Bakelite cage

Nylon cage

Brass cage: Y-pressed brass sheet; M: machined brass solid

Steel cage: J-pressed steel sheet
