Replace PSL Slewing Bearings

Single row four point contact ball slewing bearing 01 series is a standard model series in China. It is made of two seat rings. The balls and the raceway are with four points contact, via which the axial force, radial force and resultant moment is born simultaneously. Outer Diameter is from 280mm to 4726mm. Most models slewing ring are with ready stock or semi-finished material stock, which can deliver out within 15 days.
Standard material we adopt is 50Mn and 42CrMo. Other customized material is also acceptable. We support models selection based on your application; teeth quenching and grinding; customized surface treatment like Blackening, phosphating, galvanizing, sandblasting and etc.
In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings.
This series models are with advantage of compact design, flexible rotating and light weight. It is widely used on rotary conveyor, welding arm and positioner, light/medium duty cranes, excavators and other engineering machines. Please feel free to tell us the application you use and we can help you choose the proper model and offer you a professional solution as soon as possible.

The single-row cross-roller slewing bearing consists of two rings, with compact structure, high manufacturing accuracy, small assembly clearance, and high requirements for installation accuracy. It can bear overturning moment and large radial force and it is widely used in transportation, construction machinery and military products.
There are two basic working modes: 1. The inner ring fixes , and the outer ring rotates; 2. The outer ring fixes and the inner ring rotates. The raceways of the slewing bearing are all treated by surface induction hardening, and the quenching hardness is guaranteed to be HRC55~62, which can achieve sufficient hardened layer depth.
Slewing bearing is usually made with internal teeth, external teeth or no teeth. The heat treatment of gears is generally normalized or quenched and tempered. The tooth surface can also be quenched according to the user's requirements, the quenching hardness is HRC50-60, and sufficient depth can be guaranteed. Teeth grinding is also supported.
