Optibelt Timing Belts

Open ended or joined polyurethane timing belts.
Can be supplied in 50m rolls or cut to any length*.
Can be joined to make a belt of any length*.
Ideal for conveying applications.
Available with a range of backings and attachments.
*Note - length must be a multiple of the tooth pitch.

Other pitches and widths available include:
T20, AT20, 5M, 8M, L, H, ATL10.
Price is /metre based on a 50m roll. Please add 10% for cut lengths. Price for joined to length belts and belts with special backings and attachments on application.

Cylindrical Roller Bearings

Single row cylindrical roller bearings with inner and outer rings. Several styles are available in this series with one or two ribs on either the inner or outer rings. These can support high radial loads and higher speeds due to the cage design than the full compliment designs. The bearings are separable and easier to fit and dismantle.

Semi-Locating Type with two Ribs on Outer Ring and one Rib on Inner Ring

Single Row Deep Groove Ball Bearings - C3 Internal Clearance

C3 Bearings have an internal clearance to cope with high speed environments where excess heat is generated.

Shielded Type

With metal shields inserted into the outer raceway, these fit in closely to the inner race providing moderate protection against mechanical damage, and against the ingress of moisture, dust and other foreign objects. The shields also retain the pre-filled grease in the bearing. Shields can be easily removed for applications that only require one shield.

SK High Power Wedge Belts

SK wedge belts offer significant performance advantages with up to 97% drive efficiency with extended belt life and easier fitting.
S=C Plus length tolerance* Belts are automatically length matched to very tight tolerances and so require no matching, are easier to fit and run more efficiently in sets.
Example: SPC 5000 tolerance range = +/-2mm compared to DIN standard/other manufacturers = +/-50mm
Advanced manufacturing techniques like our rotational curing process mean that our SK belts are less prone to fatigue and absorb less power in wrapping around the pulley, resulting in improved drive efficiency and longer belt life.
*applies to belts over 1160mm length. Consult catalogue for details.
Dimensions: 487 to 12500mm.
Standard range further sizes on request.

Taper Bore Bushes

Used to fit flywheels, pulleys and chain sprockets onto an electric motor shaft.
Taper Bore Bushes are easily assembled and are an ideal method of mating to a shaft without the need for machining.
To lock the shaft tighten up two grub screws,
to unlock it you remove the screws, inserting one in the third hole and wind in to lever off the hub from the shaft.
Material: EN-GJL 200/DIN EN 1561.

Metric Sizes

Keyways to DIN 6885 Part 1.
* Bores marked have shallow keyways.

Spherical Roller Bearings

Spherical roller bearings are double row units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. We stock both the plain (symmetrical) bore (EAW33) and taper bore (EAKW33).
The symmetrical barrel rollers orientate themselves freely on the concave outer raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated.

Thrust Ball Bearings

Thrust Bearings are designed primarily to support axial loads at contact angles between 30° and 90°. Just as with radial bearings, these bearings differ according to the type of rolling element they use. With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping movement between the bearing's rolling element and raceways.
Comprising of caged ball bearing element and pair of shaft housing washers (bearing shaft washer and housing washer, and the normal contact angle is 90°. Axial loads can be supported in only one direction, radial loads cannot be accommodated. Spherical roller and needle roller versions are also available.
