Product Information

In addition to the standard horizontally balanced saddle, two other forms of common loading for linear applications include cantilevered conditions. Here, P1 = P2= (a/b)F + F. The total load for the most statically stressed slider is set as the worst-case scenario for sizing the bearing or carriage. is reasonably adequate for the Thames, but for a newcomer it may be best not to venture out while there are any boards displayed. Once you've a bit of experience under your belt, yellow decreasing is worth a go and mebe move up to yellow increasing after you've had a season's thouough experience. DC MOTOR COMPATIBLE ] : With the wheel structure designed to be compatible with DC Motors, you can mount it with any DC motor you want. HIGH QUALITY WHEELS ] : The wheels are made of high quality materials and are suitable for use on any surface. The service life of the wheels is quite long.

The other cantilevered application typically occurs when moving loads vertically. With one rail and two carriages, both the bearing carriages can be loaded equally in a radial direction because P1 = P2 = F(a/b). DESIGNED FOR PROJECTS ] : You can use these wheels in various projects. It comes with shaft adapters compatible with 3mm, 4mm D type shaft motors and L type plastic gearmotors. In this way, it offers the opportunity to use it with many engines. Duty cycle: The duty cycle parameter must consider the full motion of the saddle through a complete cycle, which is most often two times the stroke plus idle operations in a desired amount of time. The stroke of the application is the length of complete overall movement in one direction along a linear path. Typically, the duty cycle parameter is organized as the number of cycles required per minute. Each of the bearings will be equally loaded at 100 lb., because the bearings are mounted at each corner of the saddle, and the center-of-gravity of the mass is centered fore-aft and left to right. Each of the bearing carriages can handle 500 lb of maximum radial loading, so an adequate life is calculated here because the bearings are loaded within the 20 to 50% range of total capacity.Updated February 2019  These dynamic values as well as static loading values can then be organized as radial (Corad), axial (Coax), torque about “X” axis (Mx), torque about “Y” axis (My), and torque about “Z” axis (Mz). The variables can then be used in most any bearing sizing application to select to the appropriate size of carriage. Loading values are normally presented in lb or Newtons (N) statically and in.-lb or Newton Meters (Nm) for dynamic loading.

Which marina has the wide entrance out of interest? I’m happy here - it’s close two work when I need to be here and not at home. Of course, you could always move to another well known marina further upstream where the entrance is much, much wider..... The best approach to specifying and sizing linear rails is to define the most critical parameters of the application first; narrow the choices based on these requirements; and then apply critical variables to make the final linear-rail selection. The marina staff are a friendly lot - so ask - If Terry (mechanic) is still there he might be persuaded - for a fee - to act as safety boat / tug to get you started. Our trade counter service provides you with access to a friendly and efficient service and advice. Please note - ideally we ask for 30 minutes’ notice to be sure you aren’t kept waiting. How do I return faulty items?Orientation: The mounting orientation of the ways is critical for setting up the loading parameter because the saddle could be moving horizontally, vertically, along a wall-mount, or even in an inverted position. For best performance, manage the loading of the application with the strongest part of the bearing system. For example, the radial ball-bearing slider should be oriented to carry the load radially, not axially. Now make a linear-guide selection

Mounting area: The mounting area for the guide rail and saddle bearings helps to determine the overall length (O.A.L.) and rail separation of the guidance system. In most applications, it is best to consider the widest possible footprint for bearings to operate. Unless you use telescopic linear bearings, which act in a manner similar to simple drawer slides, the O.A.L. of the guide rail has to include the stroke of the linear movement as well as the bearing footprint. After selecting a system, assemble the parameters to properly size it. For each movement in a linear guideway system, consider the following parameters: stroke, load, speed, duty cycle, mounting area, and mounting orientation. Size the linear-guide system The offset of the wheel is a measurement taken from the centerline of the wheel to the mounting pad of the wheel. The higher the offset the closer the wheel is to your chassis. If you used our Search By Vehicle tool we will only show you offset ranges that are within range for your vehicle.I have tried measuring the speed of floatsam by walking at pace with it using a gps. It’s around 2.5-2.8 mph (at least on the surface). I have been told she will make 3.8-4.5 mph. In theory it seems fine as I only want to go 1 mile downstream to empty the holding tank before winter and fuel up. GET SPEED TO YOUR ROBOTS ] : This wheelset is designed to adapt to the various motors you use in your robot projects. If you want to speed up your robot projects, these wheels will satisfy you. The mounting area also needs to take into account the substrate or framing system for holding the guideway. The bearing footprint is the distance from the front of one carriage to the rear of the farthest carriage along one linear guideway. Many profiled shafts have to be mounted to completely machined and ground surfaces to properly meet the program requirements for precision. Other designs can be applied directly to structural aluminum or tubular framing without losing capacity or rigidity. We have never had a problem with Fixfirm, it’s right on our doorstep, very rarely is there something not available, staff are always friendly and helpful."
