The trapezoidal tooth profile of PowerGrip™ Timing belts offers a maintenance-free and economical alternative to conventional chain drives and is well suited for use in positioning applications.
Tapered roller bearing are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. Along with metric series bearing, inch series bearing are also available. This type of bearing is suitable for applications that involve heavy or impact loading.
The McGill® CAMROL® full complement needle bearings feature black oxide treated bearing steel. They are available in two basic mounting styles for use in mechanical automation or linear motion applications. Our basic features each contribute to superior performance. The LUBRIDISC® seal option helps prevent metal to metal contact within the bearing. It also provides a barrier for containment entry and blowout protection when relubricating. These bearings are available with several dimensional choices. The seal options and combinations provide a specific solution for each application. Within the following section you can learn more about these features and how they can be applied to your application.

O-rings are closed circular rings of circular cross-section. They are made through vulcanization from form tools as a complete ring. The sealing function of the O-ring is achieved by the deformation of the cross-section when installed and compressed in its housing. The O-ring can be compressed either radially or axially in its installation housing. In operating conditions the pressure exerted by the media reinforces the sealing function, as under pressure the elastomer material functions as a non-compressible fluid.
