Toothed Belt Rollers

Standard HTD profile with metric pitch (rounded toothing). At least one toothed belt pulley must have a rim flange. Conical hole for taper clamping bushes. The taper clamping bushes must be ordered separately and are available for various shaft diameters. Pulleys with a taper hole are statically balanced as per ISO 1940 grade G16.

Steel clamped or monobloc rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded shaft protrudes from only one end of the tube.In belt conveyors, they are vertically mounted in pairs at the edges of the rubber matting, with the function of restricting any lateral slipping. They are installed on self-centring stations with the same function.The technical characteristics of Series 6 rollers are those of the relative base rollers.Other finishes, see page 30.

Bearing assemblies with direct drive are suitable for applications where high performance and low space requirements are important criteria. The integration of the drive into the bearing housing means that wear-prone assemblies for transmitting drive power, such as toothed belts, shafts or chains, can be dispensed with. This reduces the required drive energy and also benefits more accurate positioning.

A specialized design combines an external cylinder with a cylindrical raceway and balls that are incorporated in the retainer, making rotary and linear motion in the axial direction possible simultaneously with rotational motion. Small Rolling Frictional Resistance Incorporating a ball with high accuracy into the precisely polished external cylinder results in small rolling frictional resistance and extremely smooth rolling motion together with reciprocal motion. Low Inertia Since the retainer has high rigidity and is lightweight, it has low motion inertia, making it suitable for rolling motion and reciprocal motion in highspeed operations. A Variety of Models Standard and heavy load models are available, each with different load ratings, and each offered with or without seals. It is easy to choose the right product based on the specifications of your machine or device.
