NSK Four-Point-Contact Ball Bearings

Four-Point-Contact Ball Bearings | High Axial Load Capacity for Robot Gearboxes & Servomotors
Four-point-contact ball bearings feature an inner ring split into two pieces. Just one of these bearings can sustain significant axial loads in both directions.
A contact angle of 35° allows for high axial load capacity. This type is suited for carrying pure axial loads or combined loads where the axial load is high.
These bearings feature machined brass cages.

Features

• Easy to handle
  The outer ring of these specialized single-row angular contact ball bearings can be separated from the two halves of the inner ring split along a plane perpendicular to the shaft center.
• High axial load capacity
  With a contact angle of 35°, four-point-contact bearings are well-suited for pure or combined loads where axial load is high.
• Compact
  A single bearing can be used to replace a face-to-face or back-to-back arrangement of bearings.

Applications

• Tractor transmissions, robot gearboxes, servomotors
