Single-row ball slewing ring HS Series:

The single-row four points contact ball Slewing Bearing is composed of 2 seat-rings. It features compact in design, and light in weight

The balls contact with the circular race at four points, via which the axial force, radial force and resultant moment may be born simultaneously.

It may be used for slewing conveyers, welding arms and positioners, light, medium duty cranes, excavators and other engineering machines.

1. We can supply various size.

HS series slewing bearing China's first standard JB2300-78 provided for a series, but by the time constraints, it has the main parameters of the selection and matching unreasonable, unscientific basic parameters of design, structural defects, such as too large, so that HS series of gradually fading out of the market.

JG/T66 (JJ36.1) standard series HS models included the use of more of them, called a transition series

Models listed in Table II is currently on the market can still see the JB2300-78 volleyball-type HS series of single basic parameters, it modified the original standard was mainly manifested in two aspects: First, Model Number Methods JB2300-78 Raceway Center in diameter reversed before the ball diameter. Second, the ball diameter. The former lead to confusion, which reduces the carrying capacity of slewing ring.
