Small size conveyor chain
Small size conveyor chains are roller chains or double pitch chains with added attachments for small conveying applications.
Attachments are available in a wide range of variations and can be fitted with further slats, bars and special jigs to convey any shape of material.
Engagement drive makes it no slippage and has a wide operating range to conveyor length, conveying direction and ambient conditions.
What's New / Product Information
Features and Points of Caution regarding Chain Conveyors
- ・Can convey items of almost any shape.
- ・A wide array of options available in terms of conveyor length, direction of conveyance, and ambient conditions.
- ・No slippage, allowing for accurate conveyance.
- ・Extremely durable and highly efficient.
【Points of Caution 】
- *While one positive point for chain conveyors is that there is no slippage, care needs to be taken during selection in applications with impacts.
- *Since it is a engagement mechanism between the chain and the sprocket, there is a speed fluctuation due to its characteristics.
Small Size Conveyor Chain Types and Structure
Double Pitch Chains
- ・Has double the pitch of RS Attachment Chain with a flat plate contour.
- ・Can use R or S rollers, allowing for use in various applications.
- ・Double Pitch type sprocket or RS sprocket (when the number of teeth is 30 or more with S roller) can be used.
- ・Suitable for relatively long distance and low speed conveyance.
RS Attachment Chains
- ・This chain has an attachment attached to RS Roller Chain (for drive).
- ・Since the chain pitch is small, small articles can be conveyed at a small pitch, which is generally suitable for short distance conveyance.
- ・High-speed, smooth, and quiet operation is possible.
- ・In most cases, RS sprockets can be used.

1.Plate | 2.Pin | ||
---|---|---|---|
The plate bears the tension placed on the chain. Because the accuracy of the holes into which pins or bushes are press fitted affects chain quality, plates are manufactured with particular precision and finished into tough plates with high fatigue strength and impact resistance. | The two ends of the pin are press fitted to holes in the outer plates and riveted in place. (For Hollow Pin Chain and Poly Steel Chain, they are press fitted only.) Because the pins are subject to shearing and bending forces via the plates, and because the bushes rotate and slide along the pins as the chain articulates, they are manufactured with an emphasis on strength and wear resistance. | ||
3.Bush | 4.Roller | ||
The two ends of the bushes are press fitted to the inner plate and function as bearings for the pins and rollers. They are subject to complex forces through the various parts, and are finished to specifications having high wear resistance. | Rollers are slip fit onto the bushes and reduce mechanical shock when the chain engages the sprocket. In addition, they serve to reduce running resistance by turning when the chain is in motion, making the chain run smoothly. Wear resistance is important. | ||
5.Attachments | 6.Spring Clip/Cotter Pin | ||
Bolt holes are drilled for attachments. For details, see page of Standard Attachments. | Spring clips and cotter pins prevent the connecting plates from detaching and are important components to maintain the intrinsic strength of the chain. Always install these parts. | ||
7.Inner link | 8.Outer link | ||
The ends of the two bushes are press fitted to the inner plate to form the inner link. Rollers are slip fit over the outside of the bushes. | The ends of the two pins are press fitted to the outer plates. The ends of the pins other than those on connecting links are riveted in place to prevent detachment. (For Hollow Pin Chain and Poly Steel Chain, they are press fitted only.) |
Three basic dimensions | Slip fit | Press fit | ||
---|---|---|---|---|
The pitch, roller diameter, and inner width of the inner link are referred to as the three basic dimensions of roller chain. When these dimensions are identical, a roller chain and sprocket are dimensionally compatible. | This will always fit with a clearance when the shafts and holes are fitted together. The hole tolerance range is larger than that of the shaft (pin or bush). | With this type of fit there is continuous interference when the shafts and holes are fitted together. The hole tolerance range is completely under the shaft (pin or bush) tolerance range. |
