Detailed Product Description

1) 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. 2) JG/T66 (JJ36.1) standard series HS models included the use of more of them, called a transition series. 3) 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. Cases in Table II and Table HSW35 * 1540 in a HSW1540 * 50 In addition to the number of different glib, the other basic parameters of exactly the same, but different because of the internal steel ball diameter, load-bearing capacity decreased 40%.
