Description
BANFLEX SCRUM
Features
Features of Banflescrum
- Vibration-free stable transmission
The belt bonds two or three ridges and therefore is mostly vibration-free. Hence, it allows stable transmission without the belt flipping over or detachment from the pulleys.
- Most suitable for vertical shaft drive operation
The bonding of the belt prevents contact between belts and detachment from the pulleys. Therefore, even in the case of a vertical shaft drive, there is no need to use special pulleys (such as deep-grooved pulleys).
Banflex Features common to Banflescrum and Banflex
- High-speed and smooth power transmission
The high accuracy of the belt cross-section and effective length and no variation of belt sink on the pulleys allow high-speed smooth power transmission close to flat belts. Although the previous V-belts can be used up to 30 to 40m/s, Banflescrum can be designed to be used with a speed up to 60 m/s.
- Lightweight and compact design
It can be used with small pulley diameters, allows for a high speed ratio, and allows the power transmission system to be light and compact. For example, a device that had used two-stage deceleration with V-belts can be changed to one stage deceleration.
Structure
- Compression rubber
– Polyurethane rubber with excellent abrasion resistance and large friction factor and allowable compression stress
– 60° belt angle that gives uniform load distribution
- Cord
Polyester cord with a large tensile strength, little flex fatigue, and little permanent elongation
- Reinforcing canvas
Polyamide fiber that increases the widthwise rigidity and sures stable running
- Back face rib
Unique ribs that reduce bending stress
Note
- When you use multiple Banflex belts, be sure to use the Scrum type
- To provide the dynamic performance of the belt, a “lubricant” is compounded in the belt. This compounding ingredient may become deposited in white on the belt surface due to changes in ambient temperature etc. or may become slightly wet due to a liquid. This will be absorbed into the belt with time and is no abnormality.
Belt Combinations
Banflescrum has two or three ridges as the standard. For four or more ridges, please use a combination of belts with two and three belts as shown in the following table
(The recommended maximum number of ridges is 12.)
Matched set
When using a combination of multiple belts, please specify a matched set. We deliver a set of belts of lengths within the allowable range shown in the following table

Note
Please note that when you switch from Banflex to Banflescrum, the center distance becomes shorter (3 to 5 mm for 5M → 5MS, 5 to 6 mm for 7M → 7MS, 6 to 8 mm for 11M → 11MS).
