V-belt is a collective term for trapezoidal drive belts that non-positively transmit torques in mechanical drive systems. They can be encased or raw edged. High-quality materials, careful production processes and the correct choice of product ensure maximum operational reliability. The profile, length, and material of the V-belt and the construction and material of the tension members will vary, depending on the application and specific requirements.
Timing belts / Clamping plates
We stock a wide range of the most commercially available timing belts from rubber or polyurethane, manufactured endless or by the meter. Ex stock you also receive aluminium clamping plates.
Coupling belts / Reverse idler belts
Our black reverse idler belts have been designed specifically for use with reverse idlers and do not provide controlled slip. Our grey coupling belts, on the other hand, have been designed for controlled slip and silent coupling engagement.
We stock V-ripped belts, also known as ripped belts, Poly® V-belts, Micro® V-belts or MULTIRIB® belts in profiles J, K and L manufactured to DIN 7867. Profiles M, H and DK are on request. In the motor vehicle sector mostly used is profile K.
Power belts / Composite V-belts
Power belts or composite V-belts are drive belts that are used for high impact and non-uniform loads. They ensure safe transmission of high torques and power even at large centre distances.
V-belt pulleys, also known as grooved pulleys, are machine elements and are an important component of the V-belt drive. In addition to the standard or taper V-belt pulleys, we also sell aluminium cone pulleys, variator and fixed pulleys for wide V-belts and adjustable V-belt pulleys (variable speed pulleys).
Timing belt pulleys
We supply timing belt pulleys ex stock either pre-bored or with the taper clamping bush system. The performance of a timing belt drive is strongly influenced by the quality of the associated pulley. This is a precision component manufactured using milling tools for accurate pitch. This ensures that the teeth engage precisely and the pitch of the belt and pulley match exactly.
Timing bars / Flanged pulleys
Timing bars are toothed cylinders, a type of blank used to produce customised timing belt pulleys. We supply them in the following sections: T, AT, HTD®, CDT®, MXL, XL and L. Please order flanged pulleys separately.
V-ripped belt pulleys
V-ribbed belt drives are used for high transmission ratios, with small pulley diameters, reverse idlers and at high belt speeds.
Flat belt pulleys – Taper version
Flat belt pulleys are machine elements and an important component of flat belt drives. The power is non-positively transmitted by means of friction. The construction of the drive has to be very stable in order to ensure correct, permanent alignment of the pulleys.
Roller chains / Sprockets for roller chains
Chains and sprockets are positive drive elements, usually made of steel. They transmit high torques without slip and have a very long service life when correctly handled and maintained. We supply the most popular sprockets, chains, sprocket sets, chain tensioners and gliders as well as straight and cranked links from our warehouse in Schwanden (limited range in Granges/Sierre).
Taper system clamping bushes, bolt-on hubs, weld-on hubs, intermediate sleeves
Taper system clamping bushes, bold-on hubs, weld-on hubs and intermediate sleeves are machine elements that establish a replaceable clamping connection between shaft and hub (such as V-belt pulleys, toothed belt pulleys, chain wheels, couplings etc.). Our taper system clamping bushes are always supplied with a keyway.
Tensioning pulleys / Idler pulleys / Universal tensioners
Tension rollers, sprocket sets, chain slides and belt tensioning pulleys can be used to adjust the preload force in rotary drives with fixed shafts. They do not transmit power, but can improve performance.
Our DL clamping sets or clamping elements are standardised machine elements that establish a non-positive and backlash-free connection between the shaft and hub in mechanical drive systems. Torques and axial forces are transmitted by friction.
Couplings are machine elements that transmit torques and rotational speeds between two shafts. The connection between these shafts can be rigid, separable or elastic. From stock we sell elastic couplings, matching spacers, bolts, buffers, sleeves and clamping bushes Taper system.
Roller bearings / Spherical plain bearings
We can supply high quality roller and spherical plain bearings from leading manufacturers (NTN, SNR, SKF, FAG, NKE, TIMKEN, DURBAL and others). On request we can also supply more economical bearings from less well-known manufacturers.
Radial shaft sealing rings (such as Simmerrings®), O-rings, V-rings, SKF Speedi Sleeve shaft repair sleeves, NBR rubber cords or rubber sealing cords, VK closure caps, rubber sheets as roll material and sealing or gasket paper, axial shaft sealing rings, wipers, – we stock a wide range! Please note that some of these products are only stocked at our branch in Granges/Valais!
Motor clamping slides / Motor clamping rails
Motor clamping slides and rails are an ideal mounting base for any motor. They enable easy, correct pre-tensioning of your belt drive.
