Spiral Return Roller
Leave a request and we will contact you within 10 minutes!
PRODUCT INTRODUCTION
The Spiral Return Roller is mainly used to clean the debris adhering to the conveyor belt, and it can prevent the conveyor belt from running off. The left and right spiral round steel with a welded diameter of 10mm-14mm on the top of the roller or a spiral groove cast rubber sleeve is added to the outer surface to increase the wear resistance of the entire roller, so thagtf5rdeswaqt the attachment on the top of the conveyor belt can be thoroughly cleaned, and the steel spiral roller can ensure the service life of the conveyor belt.
WHERE IS IT USED
Used on the return transom to support the belt when the material being conveyed. The helical spiral form of the non-abrasive rings, assembled onto the base roller shell, performs a cleaning action and reduces the tendency of material to deposit itself and stick to the surface of the dirty side of the belt. They may be employed on any part of the return belt section in the case of short conveyors. On long sections it is satisfactory to employ these rollers only up to the point where the material does not adhere any more to the belt surface.
PRODUCT DESIGN
The long-life and high-sealing rollers designed and produced by JUXIN are primarily developed to address the current issues in belt conveyor roller manufacturing, including low accuracy, high rotation resistance coefficient, excessive running noise, poor sealing, and inadequate design life. The rollers feature a fully sealed, waterproof, and dustproof structure, with the bearing assembly utilizing high-precision bearing chambers and special high-quality bearings. They offer advantages such as refined structure, low noise, maintenance-free operation, extended service life (over 30,000 hours), and reliable performance. Therefore, they are an excellent choice for advanced belt conveyor systems.
THE CONVEYOR BELT HAS THE FOLLOWING DESIGN
1 Pipe: This is the main part of the roller, typically constructed from steel pipe and coated with paint to enhance its anti-corrosion and wear resistance properties.
2 Bearings: Deep groove precision ball bearings, DIN 62 and 63 series, 6204, 6205, 6305, 6206, 6306, 6308, C3 or C4 clearance.
3 Seal: Labyrinth seal, its purpose is to prevent dust and debris from entering the bearing interior, three-lip type, material ISOPA6 (nylon 6).
4 Bearing housing: This component connects rollers to conveying equipment, available in fixed and adjustable types.
5 Shaft: Cold drawn steel. Raw steel rod grinders process shafts with diameters up to 20, 25, 30, 40 (ISO h6 or g6 tolerances apply to seal parts or entire shafts).
6 Lubrication: The roller assembly using waterproof, dust-proof, long-acting 3 class lithium grease, long-term lubrication.
7 Circlip spring: Made of spring steel, it serves to secure the movement of roller strings.
Collectively, these components form a complete structure that effectively supports conveyor belts and material weight while maintaining normal belt conveyor operation.
