Founded in 1990, China Famen Bearing Co., Ltd. is specialized spider coupling manufacturer and spider couplings 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.

vibration damping. electrically insulating (standard).backlash-free. press-fit design. compensation for misalignment. Safety overload couplings are used to allow for a certain amount of slippage to occur in order to prevent damage to the drive or machinery when torque exceeds a certain preset limit. These couplings consist of the following parts: A set of springs is used to apply force (springs are rated in newton/meters) to the brake linings. The springs are specific to the drive application, and cannot be substituted with other types of springs. A pair of brake linings, similar to the brake linings found in automobile drum brakes. An external drum. The brake linings are held to the inner surface of the drum by friction and pressure applied by the springs. An internal hub to hold the springs and linings together and transfer power to the brake linings. These parts are available from us separately or we can supply the entire safety overload coupling.

Electromagnetic clutches are also found in PIV drives. These types are found in PIV drives used in the paper industry. Electromagnetic clutches found in G3A5DU PIV drives of an internal clutch assembly (tracking plate, kick-in plate and coil) plus a set of external brushes. The internal clutch assembly is replaced as a unit, while it is possible to replace the external brushes and brush holders. Another type of electromagnetic clutch consists of two parts and is found in multi-step gearboxes. Soft start" couplings are used to prevent sudden jerking motions which can damage the drive or machinery when torque is suddenly applied to the shaft. These couplings usually consist of semi-elastic inserts (usually rubber or plastic) inside a metal housing, which stretch when torque is applied, thereby allowing for a gradual increase in torque to the output shaft. We usually supply our customers with the replacement inserts. The Jaw couplings from Lovejoy are offered in the industry’s largest variety of stock bore/keyway combinations. These couplings require no lubrication and provide highly reliable service for light, medium, and heavy-duty electrical motor and internal combustion power transmission applications.
