About this item

  • Bearing type: Angular contact ball bearing Model: 7011ACM Inner diameter (mm): 55.000 Outer diameter (mm): 90.0000 Width (mm): 18.0000 Weight (KG): 0.443
  • Installation precautions: Install in the correct direction according to the load direction to avoid incorrect installation direction, which may cause the bearing to be unable to effectively bear axial force and accelerate wear Avoid hitting: Try to avoid directly hitting the bearing with a hammer or other hard tools to prevent damage to the raceway or rolling elements.

  • Bearing material: GCR15 OR 52100
  • Service commitment: 24-hour online technical support service for you


The inner and outer rings of angular contact ball bearings have raceways, and the inner and outer rings can undergo relative displacement along the axial direction of the bearing. This type of bearing is particularly suitable for bearing composite loads, which are loads that act radially and axially simultaneously. The axial load bearing capacity of angular contact ball bearings increases with the increase of contact angle α. The contact angle is the angle between the line connecting the contact point between the ball and the raceway in the radial plane and the perpendicular line of the bearing axis. The models of angular contact ball bearings are divided into: angular contact ball bearings with α=15 ° (70000C type); Angular contact ball bearing with α=25 ° (70000AC type); Angular contact ball bearing with α=40 ° (70000B type); Back to back paired double contact ball bearings [70000C (AC, B)/DB type]; Face to face paired double angular contact ball bearings [70000C (AC, B)/DF type]; Series paired double angular contact ball bearings [70000C (AC, B)/DT type]; Double row angular contact ball bearings with ball installation gaps (Type 00000); Double row angular contact ball bearings (00000 A type) without ball installation gaps; Double row angular contact ball bearing (00000 A-Z type) with no ball gap and dust cover on one side; Double row angular contact ball bearings (00000 A-2Z type) with no ball gap and dust covers on both sides; Double row angular contact ball bearing (00000 ARS type) with no ball gap and a sealing ring on one side; Double row angular contact ball bearings (00000 A-2RS type) with no ball gap and sealing rings on both sides; Four point angular contact ball bearings (QJ0000 type), totaling 13 typesSingle row angular contact ball bearings can only withstand axial loads in one direction, and when subjected to radial loads, it will cause additional axial forces. And it can only limit the axial displacement of the shaft or housing in one direction. The contact angle of angular contact ball bearings is 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are non separable designs, with varying heights of shoulders on both sides of the inner and outer rings. In order to improve the load capacity of the bearing, one side of the shoulder will be machined lower, allowing the bearing to fit more steel balls
