Founded in 1990, China Famen Bearing Co., Ltd. is specialized slewing bearing manufacturer and slewing bearings distributor of all types of custom and cheap bearings. We obtained ISO9002, ISO14001, and QS9000 certificates in 1995 and 1996, 1999 respectively. Other advanced equipments include four RGB and RCI series heat treatment production lines with a treatment quantity totaling 1,500 kilograms per hour. The Multi-points temperature control meters and CNC display meters with bi-directional control have been adopted to complement these units.

The Slewing rings bearing can take moment load and radial load, besides take thrust loads; There are ball bearings, roller bearings and ball-roller bearings at type. At Type of structure, There are single-row, double-rows and three-rows. It with teeth and without teeth on conduction(outer-ring or inner-ring); At dustproof and leak grease proof type, with airproof and without airproof. At mount , It with flanged (outer-ring or inner-ring), With bolt hole and without flanged. Material often used: 50Mn & 42CrMo. Forging Certificate: DNV Certificate. Heating treatment: By professional company. Packing: Standard exporting packing. Surface process: Anti-corrosion process with special tech. Q/C: Advanced Inspection instruments. Size range: 100mm-6000mm.
It is Single Row Ball Type. There is no gear. There are two types. One is Ring Type and the other is Flange Type, the weight of which is reduced.

Slewing bearings can accommodate axial, radial and moment loads acting singly or in combination and in any direction. They are not mounted in a housing or on a shaft, but directly to a seating surface. The inner and outer rings are supplied with mounting holes. Both rings may have integral gears. They are also referred to as slewing rings and tabletop bearings. Slewing ring bearings can perform oscillating (slewing) as well as rotating movements. They may be used without gears or with internal or external gears. It is Single Row Ball Type. Gear is located with the inner side of ring. Gear is divided in two types; one is high frequency induction hardened gear and the other is quenching & tempered. The pitch circle diameter 2,000 or more is mostly made by quenching and tempering heat treatment process.
