Product Description

NTN 7944 Single Row Angular Ball Bearings features

  • High load carrying capacity
    The lower shoulder enables a large number of balls to be incorporated in the bearing, giving it a relatively high load carrying capacity.
  • Good running properties
    Rapid accelerations and decelerations are possible.
  • Easy mounting of universally matchable bearings
    No adjustment is needed for correct internal clearance or preload.

The raceways of both the inner and outer rings of this bearing type are made with a set contact angle.

Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction.
Larger contact angle type has better axial load capability.
Small contact angle type has higher permissible speed capability.

This bearing type is generally used in adjacent positions.
