Application Options
Gravity roller conveyors (RBS) are often used for semi-automatic interlinking at picking stations or kanban
shelves. You can select rollers between ø 20 and 50 mm depending on your total load and the required
spacing. The RBS-P 2065 is the best choice if you do not require the profile frame to act as a side rail –
as is the case with the RBS-P 2066 – or if the product is wider than the roller conveyor. A slope of 1 to 2°
is usually sufficient for conveying products with gravitational force. Please note that high speeds can be
reached with long lines and/or steeper slopes. This kinetic energy will require dampened deceleration.
Our roller conveyor tangential chain drive (RBT) is used wherever long conveying paths with a motorised
drive mechanism are required. The conveyor is driven by a ½" chain, which runs within an enclosed, lowwear
to drive conveying paths up to 10 m long. The chain tail is equipped with idler pulleys supported by ball
bearings for minimal friction losses.
Roller conveyors with a drive roller (RBM) allow you to drive up to nine additional rollers using the round
belt. They are notable for their few obstructing edges and easy-to-clean design, making them well suited
for clean environments and increased sanitary requirements. They are also available in an IP66 version on
request, or with an electronic holding brake for upward and downward gradients.
Rollers with a friction drive are available for dynamic buffering tracks. These rollers reduce back pressure,
and the roller remains stationary under the product without any relative motion (bi-directional friction preferred
if the load distribution is uncertain). Adjustable friction rollers are particularly useful for lightweight

wear strip to tangentially drive the conveyor rollers from below via a sprocket wheel. It can be used
products. Gripping of the product can be increased up to the adhesion limit between the product and the
roller. This is used, for example, for high acceleration, for inclines or for positioning the product.
