Power transmission is the transfer of energy from its place of generation to another location where it is applied to perform work using simple machines and linkages. We offer a wide range of rotary motion components used to transmit, convert, and control motion in your industrial systems. Our diverse line of rotary bearings includes ball, roller, cam-follower, sealed, shielded, open, and mounted. These bearings are available in a variety of materials and comply with radial, axial, and multi-directional force requirements. We also carry an array of collars, couplings, joints, and rod ends to inhibit misalignment of shafting components. Belt styles include standard and cogged with multiple cross-section options. We have pulleys, tensioners, and idler shafts to suit many applications, as well as a selection of miter and spur gears in a range of bore sizes. Compatible gear racks are also available.

Roller Bearings

In stock Limited availability

Roller bearings can offer higher load capacities than ball bearings by virtue of their line contact versus point contact (used in ball bearings). These bearings can be utilized for general use and within engine connecting rods.

Ball Bearings

In stock Limited availability

Ball bearings are capable of rotational speeds that exceed the limits of a plain bearing. Available in sealed, shielded, metal, non-metal and open versions.

Mounted Bearings

In stock Limited availability

Mounted bearings and housings with rolling bearings support a rotating shaft, which can be bolted on a machine frame or any other substurcture. There is no need to precisely machine a bearing housing in a surrounding casing. This makes these solutions cost-efficient and easy to use, while providing full rolling bearing performance.

Rigid Couplings

In stock Limited availability

Featuring one-piece clamp, two-piece clamp and set screw styles. Keyed and keyless bores available. Clamp screws are forged and treated with an anti-vibration coating to keep them from loosening.

Collars

In stock Limited availability

Shaft collars have extremely diverse applications and fall into three main categories, positioners, spacers and limiters. Reid Supply has all the main types from one-piece, two-piece, hinged, set screw aand self-locking shaft collars that will fit most shaft types from round to keyed, threaded or even a support rail.

Joints

In stock Limited availability

Available in solid and bored options, the shape of the yoke is a special feature which results in exceptionally high strength, yet allows full, free movement of the joint. This accounts for the high horsepower capacity at high speeds.

Keyed Shafts

In stock Limited availability

A keyed shaft works in unison with a rotating machine element to transmit torque to power transmission components. Available in various key sizes and diameters.

Gears

In stock Limited availability

Reid Supply offers miter and spur gears which are amongst the most economical gears in the power transmission industry. Spur gears are used to transmit power between parallel shafts while miter gears are used to transmit power between perpendicular shafts.

Gear Racks

In stock Limited availability

Gearing systems are less intricate and have lesser mating components compared to other linear motion components. This allows gear racks to be able to function over long distances.

Dampers

In stock Limited availability

Rotary dampers provide an invisible yet valuable service as a maintenance-free machine element to allow controlled deceleration of rotary movements. They are often necessary to make careful opening and closing of small lids, compartments and drawers possible. They protect sensitive components while increasing the quality and value of products. They are easy to integrate. The harmoniously gentle movements of these little decelerators can be achieved with continual rotation or with limited pivoting angles.
