FENNER DRIVES

Fenner Drives, a brand of the Fenner Group (part of Michelin since 2018), is a manufacturer of mechanical power transmission and motion control components. The brand is known for its keyless locking assemblies, belt and chain tensioners, and UHMWPE guide rails. Fenner Drives products are used in industrial applications requiring precise shaft-hub connections, belt tracking, and tension management. The product line includes multi-screw and single-nut locking assemblies (keyless bushings) in both inch and metric configurations, covering shaft diameters from 3/4 in to 2 7/16 in and 20 mm to 45 mm, with outer diameters up to 3 47/64 in and widths up to 1.358 in. These components are typically oil-dipped steel, available in flanged or non-flanged variants, and designed for high-torque transmission without keyways. Additionally, Fenner Drives supplies UHMWPE belt guides (crowned and flat profiles) in 10 ft lengths, suitable for conveyor and power transmission systems. The brand's engineering focus is on reducing installation time, eliminating backlash, and providing corrosion-resistant solutions for harsh environments. 3G Electric stocks over 178 SKUs of Fenner Drives products, including keyless bushings and guide rails, with datasheets and logistics support for global procurement. The catalog covers standard and metric sizes, enabling engineers to select components based on shaft diameter, torque requirements, and mounting configuration. Fenner Drives components are commonly specified in packaging, material handling, food processing, and automotive assembly lines where maintenance-free operation and precise alignment are required.

Frequently asked questions

Common questions about FENNER DRIVES from 3G Electric.

What types of keyless bushings does Fenner Drives offer?

Fenner Drives offers multi-screw locking assembly and single-nut locking assembly keyless bushings. Multi-screw types use multiple set screws for clamping, while single-nut types use a single nut for axial tightening. Both are available in inch and metric shaft diameters, with flanged or non-flanged options. The bushings are made from oil-dipped steel for corrosion resistance and are designed to transmit torque without keyways, reducing backlash and installation time.

What are the shaft diameter ranges for Fenner Drives keyless bushings?

Fenner Drives keyless bushings cover inch shaft diameters from 3/4 in to 2 7/16 in and metric diameters from 20 mm to 45 mm. Outer diameters range from 1 1/2 in to 3 47/64 in, with widths from 0.787 in to 1.5 in. The specific size depends on the model and configuration (flanged or non-flanged). Always verify the shaft diameter and torque requirements against the datasheet.

Are Fenner Drives belt guides suitable for crowned or flat pulleys?

Yes, Fenner Drives UHMWPE belt guides are available in profiles for both crowned and flat pulleys. The GR1001L120.00 model is designed for crowned V-belts, while the GR1101L120.00 is for flat belts. Both are 10 ft long, 0.79 in high, and 0.56 in wide, made from UHMWPE for low friction and wear resistance. They are used to guide belts and reduce edge wear in conveyor and power transmission systems.

What materials are Fenner Drives keyless bushings made from?

Fenner Drives keyless bushings are typically made from oil-dipped steel. The oil dipping provides a protective coating against corrosion and reduces friction during installation. Some models may have additional surface treatments, but the standard material is steel. The bushings are designed for high-torque applications and are compatible with standard shaft tolerances.

Can Fenner Drives keyless bushings be used in metric systems?

Yes, Fenner Drives offers metric keyless bushings for shaft diameters such as 20 mm, 45 mm, and others. For example, the T301020 model is a metric multi-screw locking assembly for a 20 mm shaft, with M6 x 20 screw threads. The B601045 model is a flanged metric bushing for a 45 mm shaft. These components are designed to metric dimensions and are interchangeable with standard metric shafts.
