RTB M1 The rollers are only extending on one side of the belt - the top. Accumulation roller provide less friction between the belt and the conveyed product and ensure the best possible sideways loading of the belt. RTB M2 The rollers are only extending on two sides of the belt - the top and the bottom. When the belt rollers are rotating, the conveyed products will move faster than the belt. When the belt rollers do not rotate, the conveyed product will travel at belt speed. RTB Straight Running Roller Conveyor Belt Belt pitch: 50.8mm Open area: 0% Assembling method: Bulke design, Without using rods Roller Top:used in a variety of low-pressure accumulation applicationsLarge production base, covering an area of 20000 square meters, standardized production and operation mode, timely delivery, low price and good quality.Our company has passed FDA certification and ISO9001 quality management system certification, and has more than 200 patents.Our customer service personnel provide one-on-one service with you to solve problems in a timely and accurate manner.0°: Rollers oriented in longitudinal direction for low back pressure applications and product accumulation. 30°, 150°, 60°, 120°:  Designed for alignment and centering. 90°: Rollers oriented in lateral direction for easy transverse movements and side transfers.Modular belts are constructed with modules molded from thermoplastic materials connected with solid plastic rods. Except for narrow belts (one complete module or less in width),all are built with the joints betweenmodules staggered with those of adjacent rows in a "bricklayed" fashion. This structure can enhancetransverse strength and it is easy for maintain.
