Parallel return roller: I. Structural characteristics
Concise design: Usually composed of components such as rollers, bearings, and shafts. The structure is relatively simple and easy to manufacture and install.
Standardized dimensions: The size specifications are relatively uniform, which is convenient for use with different types of conveyor belt systems.
II. Performance characteristics
Stable support: Provides uniform and stable support for the return conveyor belt, preventing the conveyor belt from sagging and excessive deformation.
Low-friction operation: The friction coefficient between it and the conveyor belt is small, reducing energy loss and making the conveyor belt run more smoothly.
Wear resistance: Made of wear-resistant materials or treated specially, it can withstand long-term friction and impact and has a long service life.
Good sealing performance: Effectively prevents impurities such as dust and moisture from entering the inside of the idler, protects key components such as bearings, and reduces the possibility of failures.
III. Characteristics of application scope
Widely used: Applicable to various types of belt conveyors, especially performing outstandingly in long-distance transportation and large-capacity transportation systems.
Adapt to different working conditions: It can work normally under different working environment temperatures, humidities, and dust conditions, and has strong environmental adaptability.
IV. Maintenance characteristics
Convenient maintenance: Due to the simple structure, maintenance personnel can easily perform operations such as inspection, lubrication, and replacement of parts.
Low cost: Compared with other complex conveying components, parallel return idlers have lower maintenance costs, reducing the operating cost of the entire conveying system.
Roller/idler introduction:
Our company specializes in R&D, developing and manufacturing of belt conveyors as well as various types of idlers/rollers, pulleys and roller brackets. Rollers/idlers are important components of belt conveyors. Their function is to effectively support the conveyor belt and the materials carried on the conveyor belt, ensuring the normal operation of the conveyor. The diameters of idlers have domestic standards and foreign standards. Domestic standards:Φ63,Φ76,Φ89,Φ108,Φ133,Φ159,Φ194,Φ219; Foreign standards: Φ 89,Φ102,Φ114,Φ 127,Φ 139,Φ152,Φ 165,Φ 178 and other specifications. 2.Our available rollers/idlers: Carrier roller/bearing roller/carrying roller/spiral roller/friction roller/impact roller/rubber impact roller/buffer idler/trough roller/grooved roller/troughing roller set/comb roller/return roller/self-aligning roller/self-cleaning roller/carrier self-aligning roller/return self-aligning roller/edge roller/friction roller/carrier friction roller/return friction roller/roller set/roller bracket/impact roller set/carrier taper self-aligning roller/return taper self-aligning roller/parallel roller/Belt Conveyor Roller /Conveyor Idler/troughing idler 3.Roller/idler material specification: Shaft: 45# STEEL.Cold-drawn steel S235JRG2 (EN10027-1); ST37 (DIN17100); E24 (AFNOR NFA 35501).
