Founded in 1990, China Famen Bearing Co., Ltd. is specialized spiral conveyor manufacturer and spiral conveyors 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 Ryson Spiral Conveyors represent a new concept in vertical conveying, based on a proprietary low friction chain slat arrangement. The Ryson Spirals are attractive because they have a higher throughput capacity, require less space, generate less noise, consume less energy, cost less to install, need less maintenance and have a longer life compared to conventional methods. The spiral conveyors are also known as spiral or case lifts, spiral elevators, and spiral lowerators.High Throughput.The spirals convey loads up or down in a continuous flow, thereby facilitating high throughput. The standard load capacity is 75 pounds per linear foot of conveyor for speeds up to 200 feet per minute.
One Drive
The Ryson Spiral Conveyors need only one drive motor, even for units several stories tall. This equals to substantial savings in controls and systems integrations.
Small Footprint
The Ryson Spiral Conveyors have the smallest footprint available and therefore provide substantial space savings compared to conventional methods. Several standard sizes are available and the outside diameter varies depending on the size of loads to be handled.

The overlapping slats provide a smooth efficient conveying surface suitable for a wide variety of load types and sizes. The slats are made of a fiberglass reinforced Polyamide and are available in widths of 8", 12", 16", 20" and 26". The slats can also be furnished with friction inserts to accommodate slick products such as plastic totes or frozen items.
Low Angle of Incline
The standard angle of incline is between 9 and 11 degrees which safeguards against loads sliding or tumbling during operation.
Easy to Install
Most spirals are shipped in one piece, pre-assembled and pre-tested, thereby drastically reducing the time and cost of installation.
Low Maintenance
The Ryson Spiral Conveyors are designed for low maintenance and long life. Only high quality components requiring little maintenance are used throughout. The roller bearings are sealed and lubricated for life. The chain is of a heavy-duty chrome plated construction. The slats and carriers need no maintenance and can easily be replaced as single components without the use of special tools.
